Quick answer
Fountain Valley businesses deal with three local rules most often: the City's grease ordinance for food service (interceptors, pumping records kept 2 years, staff training every 6 months), backflow assemblies tested by an Orange County Health Care Agency certified tester, and a City permit for plumbing and gas work. We schedule licensed C-36 contractors after hours. Call (657) 669-4766.

Commercial plumbing services for Fountain Valley businesses
We handle the plumbing that keeps a business open: drains and grease lines, restrooms, water heaters, backflow assemblies, gas lines and leaks, scheduled around your hours.
Fountain Valley's commercial plumbing is spread across a few kinds of property. Restaurants and shops sit in retail centers along Brookhurst St and the city's other main streets. Offices, light industrial buildings and corporate campuses fill the Southpark business district. And with Fountain Valley Regional Hospital and Orange Coast Memorial Medical Center both in the city, medical and dental practices are part of the local mix too. Each type of business has its own plumbing pressure points.
Medical and dental offices
Restrooms and hand sinks used all day, sterilization and lab sinks, water heaters, backflow assemblies, and leak repairs that cannot wait for a slow week.
Retail centers
Shared restrooms, tenant improvements, water heaters, drain stoppages and leaks in units that share walls and slab with a neighbor.
Offices and Southpark buildings
Restroom cores, break room sinks, drinking fountains, irrigation backflow, and water heaters serving several floors or suites.
Property managers
One number for several buildings, written prices before work starts, and permits pulled when the job calls for one.
After-hours work
Planned work before opening or after closing, and calls answered 24/7 when something fails mid-shift.
We do not list clients on this site. Work is performed by independent plumbing contractors licensed by the California Contractors State License Board in the C-36 Plumbing classification. You can verify any license in under a minute with our plumber license guide.
Grease interceptors and Fountain Valley's FOG rules for restaurants
The City of Fountain Valley runs the fats, oils and grease (FOG) program for its food service establishments, and it requires grease interceptors at new, remodeled or spill-history kitchens.
OC San, the regional sewer agency whose Plant No. 1 sits in Fountain Valley, says it relies on the cities and agencies it serves to run FOG programs for food service establishments that discharge to local sewers. In Fountain Valley, the City inspects restaurants and other food businesses that produce grease, under its Grease Ordinance. Here is what the City's grease page says.
| Rule | What the City says |
|---|---|
| When an interceptor is required | Facilities that are newly built, remodeled or change operations, or that have had a sewage spill since May 20, 2001 |
| What counts as remodeling | A physical change needing a permit, including under-slab plumbing in the food prep area, a 20 percent increase in public seating or kitchen area, or a change in the size or type of food prep equipment |
| Occupancy | No Certificate of Use and Occupancy is issued until a required grease control device is installed, inspected and approved |
| Minimum interceptor size | 750 gallons |
| Pumping | By a licensed liquid waste hauling company, typically 4 times a year depending on the type and volume of food prepared |
| Records | Keep all manifests, receipts and invoices for cleaning, maintenance and grease removal for at least 2 years |
| Screens | Food screens on all kitchen sinks and floor drains |
| Food grinders | Prohibited at new food facilities |
| Staff training | Back-of-house staff trained every 6 months, with a signed training log kept where inspectors can see it |
| Signs | Post NO GREASE signs so staff do not pour cooking grease, hood grease or other fats down drains |
| Existing kitchens | Facilities in continuous operation that were never required to install an interceptor and never caused a spill can operate without one |
If an interceptor is impossible or impractical at a site, the City says the Building Official may require alternatives, such as other grease control devices, maintenance assurances, or bonds or payments. The City also requires interceptors in new multiple dwelling units and in ones that have had a sewer overflow.
Where a plumber fits in
The City's page says interceptor maintenance is done by a licensed liquid waste hauler. A plumber's part is the plumbing around it: installing or replacing an interceptor during a remodel, repairing inlet and outlet piping and baffles, adding sink and floor drain screens, and jetting the kitchen lines that feed it. When the lines between the sinks and the interceptor are coated with grease, a pump-out alone does not fix slow drains. Our drain cleaning and hydro jetting service clears them.
Backflow testing for Fountain Valley businesses
Many Fountain Valley businesses have backflow assemblies that must be tested by an Orange County Health Care Agency certified tester, with results sent to the City's Field Services Division.
A backflow assembly keeps water from a building, an irrigation system or a fire line from flowing back into the public water supply. The City of Fountain Valley and the Orange County Health Care Agency run a cross-connection control program together. The City says businesses and some residential properties may be subject to a backflow device, and it cites Fountain Valley Municipal Code section 14.17 and California Code Title 17.
- Who can test
- An Orange County Health Care Agency certified tester who is also licensed to work in the city
- How often
- At least once a year, per an April 2026 OC Health Care Agency reminder on internal backflow assemblies
- Where results go
- Public Works, Field Services Division, 17300 Mt. Herrmann St, or by email as the City's backflow page lists
- Questions
- City Water Quality Technician, 714-593-4624
- Approved testers
- The City posts a list of approved testers on its backflow page
The OC Health Care Agency's April 6, 2026 letter says internal backflow prevention assemblies must be tested at least once per year by a certified backflow assembly tester registered with its Environmental Health division. It cites the plumbing code and the State Water Resources Control Board's 2024 Cross-Connection Control Policy Handbook.
When a test fails, the assembly needs repair or replacement before it is retested. The CSLB C-36 plumbing classification covers the maintenance and replacement of backflow preventers. We schedule the repair and coordinate the retest with a certified tester, and the City form goes back to Field Services. If you are not sure whether your building has an assembly or when it is due, the City's water quality technician can tell you.
Commercial water heaters in 13-grain water
Commercial water heaters in Fountain Valley scale up fast because City water averaged about 13 grains per gallon of hardness in 2025, and a business uses far more hot water than a home.
The City's 2026 Consumer Confidence Report shows total hardness averaging 217 ppm in 2025, with a range of 171 to 256 ppm. In 2025 the City delivered 100 percent groundwater from the basin managed by the Orange County Water District. A restaurant dish area, a salon or a medical office running hand sinks all day heats much more of that water than a household does, so sediment and scale build up faster.
- Tank heaters collect sediment on the bottom, lose capacity and get noisy. A flushing schedule matters more in a business than at home.
- Tankless units need regular descaling in hard water. Our tankless water heater page covers what that involves.
- Replacement of any water heater is plumbing and gas work, which the City requires a permit for. Our water heater repair page explains the strapping and expansion control California code requires.
- Water treatment before the heater can cut scale for the whole building. See our water softener and filtration service.
When a water heater fails in a food business, it can stop service, since hand sinks and dishwashing need hot water. Calls like that go to our 24/7 emergency line, and we give an honest arrival window when you call.
Plumbing for medical and dental offices
Medical and dental offices need plumbing that works every hour they are open, so we plan repairs and upgrades around patient schedules.
Fountain Valley has two hospitals, Fountain Valley Regional Hospital with about 400 beds and Orange Coast Memorial Medical Center with about 230. Medical and dental suites in town range from single-practice offices in strip centers to multi-tenant buildings. What they have in common is a lot of hand sinks, restrooms used all day, and little room for downtime.
- Hand sinks and faucets. Constant use and hard water wear out cartridges and aerators.
- Restrooms. Flush valves, wax seals and clogged lines get fixed before or after patient hours where possible.
- Hot water. Small tank or point-of-use heaters serving exam room sinks need the same scale management as any Fountain Valley heater.
- Backflow. Medical and dental equipment connected to the water supply may sit behind a backflow assembly that needs yearly testing.
- Gases and vacuum. The CSLB C-36 classification includes piping for vacuum, compressed air and gases for medical and dental uses. Tell us which systems your suite has, and we confirm the right licensed contractor for that work before scheduling.
For a leak inside a wall or under a slab in an occupied suite, our leak detection service finds the source before anyone opens a floor in a patient area.
Retail centers on Brookhurst St and across Fountain Valley
In a strip center, one tenant's clog or leak often becomes the neighbor's problem, because suites share walls, slabs and sewer lines.
Much of Fountain Valley's retail sits in shopping centers along Brookhurst St and the other main streets. A typical single-story center has several suites on one slab, with restroom and kitchen drains tying into shared lines that run behind the building to the sewer. That layout shapes the plumbing work:
- Shared drain lines. A backup at the end suite can start in a restaurant two doors down. A sewer camera inspection shows where the line is blocked or broken, and who it serves.
- Tenant improvements. New restrooms, a break room sink or a change of use usually need permitted plumbing. A change to a food use can trigger the City's grease interceptor rules.
- Water-conserving fixtures. California Civil Code 1101.5 required noncompliant fixtures in commercial property to be replaced by January 1, 2019. It also requires replacement as a condition of final permit approval for some work: additions that grow floor area by more than 10 percent, alterations costing more than $150,000 for the area improved, and any permitted work in a room with noncompliant fixtures.
- Gas lines. New cooking equipment or a water heater upgrade can need a bigger gas line. Our gas line plumber page covers customer-side gas piping.

Commercial plumbing permits in Fountain Valley
Commercial plumbing and gas work in Fountain Valley needs a permit from the City's Building Division at City Hall, except for small repairs the City lists as exempt.
The Building Division is at 10200 Slater Ave, phone 714-593-4429, with counter hours Monday to Thursday, 7 a.m. to 6 p.m., closed Fridays. It also takes applications through the online Permit Center. The City's handouts page lists a Summary of Accessibility Upgrades for Commercial Projects and a nonresidential CALGreen mandatory measures form, both of which can come up during tenant improvements. The City notes that its handouts are under review and that it has adopted the 2022 California codes, possibly with local amendments.
The Work Exempt from Permits handout covers clearing stoppages and repairing leaks in pipes, valves or fixtures, as long as no valves, pipes or fixtures are replaced or rearranged. Anything beyond that, such as a new interceptor, a water heater replacement, a new restroom or a gas line for new equipment, is permitted work. Our Fountain Valley plumbing permit guide covers the details.
What commercial plumbing costs
Commercial jobs are priced one at a time because access, hours, fixture counts and permits vary so much; you get a written price before work starts.
We do not publish commercial prices, and no third-party source we trust publishes reliable Fountain Valley commercial figures. The published national figures below are for residential jobs. They show the scale of common line work, but a commercial kitchen line or a multi-suite sewer usually costs more.
| Job | Published figure | Source |
|---|---|---|
| Hydro jetting, per line | $350 to $600 | Angi, 2026 |
| Sewer line camera inspection | $275 to $1,800 | Angi, 2026 |
| Main sewer line clearing | $100 to $800 | HomeAdvisor, 2025 |
| Gas line installation, per line | $272 to $936 | HomeAdvisor, 2025 |
What moves a commercial price: after-hours timing, how many fixtures or suites are involved, roof or ceiling access, interceptor size and location, permit and inspection scheduling, and whether the work must be done in stages to keep the business open. More published figures are in our plumbing costs guide.

Questions Fountain Valley homeowners ask
Does my restaurant in Fountain Valley need a grease interceptor?
If the restaurant is new, remodeled, changed operations, or had a sewage spill since May 20, 2001, yes. The City of Fountain Valley requires a grease interceptor of at least 750 gallons in those cases. Kitchens in continuous operation that were never required to have one and never caused a spill can operate without one.
How often does a grease interceptor need to be pumped in Fountain Valley?
The City says typically 4 times a year, depending on the type and volume of food prepared. A licensed liquid waste hauler does the pumping, and you must keep all manifests, receipts and invoices for at least 2 years for City inspectors.
Who runs the FOG program in Fountain Valley, the City or OC San?
The City of Fountain Valley inspects restaurants and other food service establishments under its Grease Ordinance. OC San says it relies on the cities and agencies it serves to run FOG programs for food businesses that discharge to local sewers.
How often does a backflow preventer need to be tested?
At least once a year. The Orange County Health Care Agency's April 2026 reminder says internal backflow assemblies must be tested yearly by a certified tester registered with it. The City of Fountain Valley requires an OCHCA certified tester licensed to work in the city.
