Dealing with a slow drain or a sudden burst pipe? M.O.D. Plumbing has been serving Rohnert Park and the wider Sonoma County area since 1992, and in that time we have handled just about every plumbing situation a home or business can throw at a person. We work with homeowners, landlords, property managers, and commercial clients, covering everything from a dripping faucet to a full sewer line replacement. Local roots mean we are invested in getting your plumbing right. Right diagnosis. Right repair. Right the first time. Call (707) 899-1595 for a quote, and we will give you no-pressure estimates, priced up front, before any work begins.
Whether this is your first plumbing repair or your tenth, you deserve straight answers about your pipes and fixtures, no surprises. We handle the full range of residential and commercial plumbing work, from routine drain cleaning to whole-home repiping, and every job is performed by licensed plumbers who know the work inside and out.
A clogged drain is one of those problems that rarely fixes itself. We clear kitchen drains, bathroom drains, floor drains, and main line clogs using the right tools for the job, including hydro jetting for stubborn buildup in sewer and main lines. Whether it is a slow bathtub drain or a backed-up main line affecting the whole house, we locate the blockage and clear it completely.
Water leaks hide in walls, under slabs, and beneath sinks, often doing damage long before they are noticed. We use diagnostic methods to pinpoint the source accurately, then repair or replace the affected pipe or supply line. Slab leaks, broken water lines, and under-sink drips all get the same careful attention. Catching a leak early keeps repair costs down and protects the structure of your home or building.
No hot water is one of the more disruptive plumbing problems a household faces. We repair and replace both tank and tankless water heaters, diagnose heating element failures, address sediment buildup, and handle full unit replacements when a repair no longer makes sense. We will cover tankless installation in more detail in the regional section below, but whether you are keeping your current unit running or upgrading to something more efficient, we handle it all.
From a running toilet to a new faucet installation, fixture work is some of the most common plumbing we do. We repair and replace toilets, faucets, sinks, showers, outdoor hose bibs, and garbage disposals for homes, rental units, and commercial properties. If a fixture is wasting water, leaking, or simply worn out, we can swap it for something that works properly and meets current code.
A sewer line problem can bring a property to a halt. We clear, repair, and replace the main sewer line running from your home or building out to the city connection. That includes main line cleaning, camera inspection to identify blockages or damage, and pipe repair or full replacement where the line has deteriorated. We speak to the line itself and handle it thoroughly.
Older homes across Sonoma County often carry aging galvanized or original copper lines that have reached the end of their useful life. Low water pressure, discolored water, and recurring leaks are common signs that a repipe is worth discussing. We assess the existing system, explain the options clearly, and complete the work with minimal disruption to the home or business.
If you're not sure your water pressure is where it should be, it is worth having it checked. Low pressure can point to a failing pressure-regulating valve, a partially closed shutoff, or pipe corrosion. We diagnose pressure problems accurately, replace shutoff valves and pressure-reducing valves, and install expansion tanks where needed. Getting pressure right protects fixtures and extends the life of your plumbing system.
We handle gas supply line work for appliances throughout the home or building. If a gas line needs to be repaired, rerouted, or extended to reach a new appliance, we do that work safely and to code. Your pipes are in good hands with us.
No matter what is going wrong with your pipes, the type of property you own shapes what the job looks like. For homeowners, we handle everything from remodel rough-ins and new fixture installations to emergency repairs and full system upgrades. If you are renovating a kitchen or bathroom, we can coordinate the plumbing side from start to finish.
For landlords, property managers, and commercial clients, we understand that a plumbing problem in a rental unit or business space needs to move quickly. A family-run plumbing business like ours stays personally accountable for every job. We work around tenant schedules, respond to property managers directly, and keep commercial disruption to a minimum. Give us a call and we will get the water sorted.
Choosing the right plumbing fix is easier than it sounds when you have someone reliable to call. When the situation cannot wait, we are available for same-day and after-hours service. Burst pipes, major leaks, flooded utility rooms, and sudden loss of hot water are all situations where waiting a day is not a reasonable option. We get to the problem fast, assess what is happening, and get to work. Leak found. Leak fixed. Water back on. Call (707) 899-1595 now and we will get someone out to you.
Northern California has a specific set of plumbing demands that do not show up everywhere else. A mild climate, persistent drought pressure, active seismic zones, and California's conservation requirements all shape what homeowners and property managers here need from a plumber. The three services below come up regularly in this part of Sonoma County, and we have built real experience handling each one.
Tankless water heaters are a strong fit for Northern California homes. Mild winters mean the units are not fighting extreme cold, energy-efficiency programs in the region make the upgrade financially sensible, and the space savings matter in smaller homes and apartment units where a large tank is awkward to place. We size, install, and service tankless units, and we handle the transition from a tank system to tankless when a homeowner is ready to make that switch. If your current tankless unit is underperforming, we diagnose and repair those systems as well.
California's water conservation requirements are not going away, and Sonoma County has experienced enough drought years that efficient fixtures are no longer just a preference. They are practical. We install low-flow toilets, WaterSense-rated faucets, and efficient showerheads that meet current code and reduce water use without sacrificing performance. For properties with older fixtures throughout, a planned upgrade can make a measurable difference on the water bill and keep the property current with local requirements. We take pride in the plumbing work we leave behind, and that includes installations that hold up and perform the way they should.
Sonoma County sits in an active seismic zone, and an automatic earthquake gas shutoff valve is one of the more straightforward protections a property can have. These devices are installed on the gas supply line and close automatically when seismic activity reaches a threshold, stopping gas flow before a leak can develop. Work is performed by licensed plumbers and done to code. If your property does not have one installed, or if an existing valve needs inspection or replacement, call us and we will walk you through what is involved. Call and we will get your water back on.
Choosing the right plumbing fix is easier than it sounds when the estimate process is clear. When you call, describe what you are dealing with, and we will give you a straight assessment of what the job involves and what it will cost before any work starts. No-pressure estimates, priced up front, so you know what you are agreeing to. We do not believe in vague pricing or after-the-fact surprises. We take pride in the plumbing work we leave behind, and that starts with honest communication before the first wrench turns.
Rohnert Park is our home base, and we serve customers throughout the surrounding area. If you are in Cotati, Petaluma, Santa Rosa, Sebastopol, Windsor, or Healdsburg, we are familiar with the neighborhoods, the housing stock, and the local plumbing conditions. We cover a broad stretch of Sonoma County and are close enough to respond quickly when something goes wrong. If you are not sure whether we reach your area, call and ask.
Water stains on walls or ceilings, a mildew or musty smell with no visible source, flooring that feels soft or warped, and a water bill that has jumped without explanation are all common indicators. Slab leaks in particular can go undetected for a long time because the water is moving beneath the foundation. If you are seeing any of these signs, call us and we will walk through the diagnostics.
A tankless unit heats water on demand rather than keeping a full tank hot around the clock, which reduces energy use and frees up space. For Rohnert Park homes, the mild Northern California climate means tankless systems operate efficiently year-round without fighting extreme cold. We assess your existing plumbing connections, size the unit correctly for the household demand, and complete the installation to code.
Inconsistent hot water, a unit that takes much longer than it used to heat up, visible rust or corrosion on the tank, water pooling around the base, and a unit that is more than ten to fifteen years old are all worth having looked at. We assess the condition of the unit and give you an honest recommendation on whether repair or replacement makes more sense for your situation.
Low-flow toilets, WaterSense-rated faucets, and efficient showerheads are the most practical upgrades for homes in this area. California's conservation requirements and the drought years Sonoma County has experienced make efficient fixtures a sensible investment rather than just a preference. We handle the full installation from selection through final connection.
An automatic earthquake gas shutoff valve installs on the gas supply line and closes automatically when seismic movement reaches a set threshold, cutting the gas supply before a leak can develop. Sonoma County sits in an active seismic zone, and these valves are a straightforward protective measure for homes and rental properties. We install and replace these valves and can tell you whether your current setup has one in place.
We run a camera through the sewer line to get a direct view of the interior condition, looking for blockages, root intrusion, cracks, or sections of pipe that have deteriorated. It is the most accurate way to understand what is happening inside the line before committing to a repair approach. If we find damage, we walk you through the options and the cost before any work begins.
A persistent sewer smell indoors typically points to a dry trap, a cracked drain line, a venting problem, or a blockage that is allowing gas to back up into the home. These situations are worth addressing promptly because sewer gas is more than just unpleasant. We diagnose the source and repair it properly.
Burst pipes, major active leaks, sewer backups affecting the whole property, a complete loss of water supply, and a water heater that has failed and is leaking onto the floor all qualify. If the situation is causing active damage or makes the property unusable, it is an emergency. Call (707) 899-1595 and we will assess the urgency and get someone out.
Shut off the main water supply if a pipe has burst or is leaking heavily, and turn off the water supply valve to a specific fixture if the problem is isolated there. Avoid using drains if you have a sewer backup. Do not try to open walls, cut into pipes, or apply temporary patches that could make the repair more complicated. Keep the area clear so the plumber can access the problem quickly when we arrive.
We start by checking the pressure-regulating valve, the main shutoff, and individual fixture shutoffs to identify where the restriction is occurring. Corroded pipe interiors, a failing PRV, and partially closed valves are the most common causes. Once we find the source, we repair or replace the component responsible and verify that pressure has returned to a normal range throughout the home.
We explain the condition of the existing system, walk you through the replacement options, and give you a clear price before any work begins. For a water heater, that includes sizing the new unit correctly for the household. For a repipe, we map out the scope, discuss materials like copper or PEX, and minimize disruption to the home during the work.
Someone with access to the property and the ability to authorize the work needs to be present when we arrive. For rental properties, a property manager or authorized representative can fill that role. If you have questions about scheduling around work or tenant availability, mention it when you call and we will work out the logistics with you.
We assess the condition of the existing valves and supply lines, identify any that are corroded, seized, or no longer holding a reliable seal, and replace them with current-spec components. This work is especially common in older homes throughout Sonoma County that still have original plumbing hardware. Getting shutoff valves in working order is important because a valve that will not close in an emergency is not doing its job.

How do I know if my water heater needs to be repaired or replaced?
Age is one of the clearest indicators. Most tank water heaters have a useful life of eight to twelve years, and units approaching or past that range are worth evaluating carefully when problems come up. Inconsistent hot water, rumbling or popping sounds during heating, rusty or discolored water at the tap, and visible corrosion around the tank or connections all point toward a unit that is nearing the end. We assess the situation and give you a straight answer about whether a repair makes sense or whether replacement is the better long-term value.
What causes drains to clog and back up?
In kitchen drains, grease and food debris are the most common culprits. Bathroom drains collect hair, soap residue, and mineral buildup over time. Floor drains and main drains can slow down due to root intrusion, accumulated debris, or a partial blockage deeper in the line. When a single fixture backs up, the clog is usually local to that drain. When multiple fixtures back up at the same time, the problem is more likely in the main line. We diagnose which situation you are dealing with before recommending a fix.
How are hidden leaks found without tearing open walls?
We use pressure testing and specialized detection equipment to locate leaks that are not visible at the surface. Slab leaks, which run beneath the concrete foundation, require careful tracing to pinpoint before any concrete is opened. The goal is to locate the leak as precisely as possible so the repair is targeted rather than exploratory. We explain what we found and what the repair involves before any work begins.
Upfront Quotes With No Surprise Fees
We explain the scope and the cost before any work begins. You will not see a number change after the fact because we take the time to assess the job correctly before we quote it.
Is the plumbing work permitted and done to California code?
Every repair and installation we complete meets current California plumbing code. Work is performed by licensed plumbers on every job. For projects that require a permit, we handle that process as part of the job. That matters for safety, for your homeowner's insurance, and for the long-term integrity of the plumbing in your home or building.
What is the difference between a tank and a tankless water heater?
A tank water heater stores a set volume of hot water and keeps it heated continuously, which means some energy is used around the clock whether or not you are drawing hot water. A tankless unit heats water on demand as it flows through, so there is no standby heat loss. Tankless systems tend to cost more upfront but can reduce energy use over time, especially in a mild climate like Sonoma County's where the incoming water temperature is not as cold as in northern states. We can walk you through both options based on your household size, usage patterns, and available space.
What causes low water pressure throughout the home?
Low pressure can come from several sources: a partially closed main shutoff, a failing pressure-regulating valve, mineral buildup inside older galvanized pipes, a leak somewhere in the supply line, or a problem at the municipal connection. When pressure drops at every fixture rather than just one, the issue is usually upstream in the supply system rather than at a single fixture. We diagnose the source and explain the repair before any work starts.
Work Performed by Licensed Plumbers
Every repair and installation is handled by licensed plumbers and meets current California plumbing code, which matters for safety, for insurance purposes, and for the long-term integrity of your plumbing.
How do I know if my sewer line has a problem?
Multiple drains backing up at the same time is one of the clearest signs. Sewage odors coming from drains or from the yard, gurgling sounds when you flush, and wet or unusually green patches in the yard above the sewer line are all worth taking seriously. Tree root intrusion is common in established neighborhoods and can cause partial or full blockages over time. A camera inspection of the line gives us a clear picture of what is going on and where.
How do estimates and pricing work?
We provide estimates priced up front before any work begins. We explain what we found, what the repair or installation involves, and what it will cost before a single tool comes out. Plumbing costs depend on the scope of the specific job, the parts required, and the access involved, so we quote your actual situation rather than a general range pulled from a chart. We do not quote a number and then look for reasons to add to it after the fact.
Same-Day and Emergency Availability
We are available every day from 5:00 AM to 8:30 PM for urgent calls throughout Rohnert Park and the surrounding Sonoma County communities. When something cannot wait, call us and we will get someone out.
Do I need to be home when the plumber arrives?
For most jobs, yes, someone should be present who can provide access to the affected areas and authorize the work once we explain the scope and price. For commercial properties managed by a property manager, we are used to coordinating access and communicating scope and pricing to whoever is the right contact. When you call to schedule, let us know the situation and we will work out the logistics.
What should I do right now if a pipe has burst?
Shut off the main water supply to the home as quickly as you can to stop the flow, then call us. Move valuables and electronics away from the water if it is safe to do so, but do not try to open walls or access pipes yourself. We will get someone out to you and walk you through what to do while you wait. We are available every day from 5:00 AM to 8:30 PM for exactly these situations.
When does a home need repiping rather than spot repairs?
Recurring leaks in different locations, consistently low water pressure, discolored or metallic-tasting water, and visible corrosion on exposed pipe are all signs that the supply system may be failing systemically rather than at one spot. Older homes in Rohnert Park with original galvanized steel supply lines are especially worth evaluating. We assess whether a targeted repair makes sense or whether whole-home repiping is the smarter long-term move, and we give you a clear picture of both options.
