Scale, worn-out appliances and Plainville's water
Aquarion's Plainville Regional system supplies the town from two groundwater well fields, one on Johnson Avenue and one on Woodford Avenue. Utility-reported data compiled by TapWaterData lists about 9.5 grains per gallon (162 mg/L) from a September 2025 sample, which that site classes as hard. A Bristol Press report on the town's own concern cites state sampling in 2017 that also read high.
The same article says hard water can build scale inside pipes and fixtures and can wear out dishwashers and laundry machines early. For you that means tanks that rumble, shower heads that clog and heating elements that burn out. Ask Aquarion for its annual water quality report to check the number for your street.
Tank water heaters
Scale settles at the bottom of a tank and insulates the burner or element. A flush slows it, and water heater repair covers failed parts.
Tankless units
Narrow heat exchangers clog first. Descaling is routine here, see tankless water heater service.
Faucets and valves
Mineral crust sticks stems and seats. A faucet that will not shut off fully can need replacing.
Dishwashers and washers
Inlet screens clog and shorten appliance life. Fix the supply side first.
Backed-up sewer: call the town, then call us
Plainville asks residents with a sewer backup to contact its Water Pollution Control Department before calling a plumber. The town runs its own sanitary sewer and a treatment plant on Cronk Road that discharges to the Pequabuck River. That first call can tell you whether the trouble is in the town main or in your own pipe.
Stop using water
Hold laundry, showers and the dishwasher. The lowest fixture, often a basement floor drain, backs up first.
Phone the WPC Department
Municipal Center, One Central Square, 860-793-0221. Ask whether the main is clear.
Call our line
If the town main is fine, we cable or hydro jet the building sewer and run a camera to see why it blocked.
Get the permit right
Any new connection needs a permit from the town's WPCA agent, and the trench stays open until it is inspected.
The sewer-use ordinance says a licensed drain layer must install a building sewer, and the owner bears the cost of installing and connecting it. It has no plain clause on routine maintenance, so ask the town which part of the line is yours before you hire. For repairs, see sewer line repair.
The Pequabuck River and your basement
Flooding from the Pequabuck River damaged homes and businesses in Plainville during Irene in 2011. Floodwater reached partway up first floors on Robert Street Extension and left oil and sewage in some houses, and federal money later bought out homes there and on Norton Place Extension. A regional hazard plan names downtown, West Main Street, Forestville Avenue, Cronk Road and Norton Place Extension as floodplain areas.
The same plan says 2021 storms caused only minor basement flooding. Still, if your basement is near any of those streets, test the sump pump twice a year and look at a battery backup. Town ordinance bars foundation drains and roof downspouts from the sanitary sewer, so send sump discharge to the yard, not the floor drain.
After floodwater touches a water heater or boiler
Water that reaches a burner or control board can damage it even after it dries. Turn the unit off and have it checked before relighting. If you smell gas, leave the house and call the gas utility or 911 before us.

Close the main valve and stay off wet floors near outlets. Then call, and dispatch will plan the next step.
Mid-century and blue-collar housing: what it needs
An aggregator summary of Census data puts about 32 percent of Plainville's 8,588 housing units before 1960 and about two thirds before 1980. An aggregator summary of Census data suggests a large share of Plainville's housing predates 1980, and the Census Bureau's own tables are the place to confirm exact figures. Plainville has plenty of older houses and plenty of renters, so the plumbing you find depends heavily on the building.
Built before 1960
- Original shutoff valves that may seize
- Older drain lines that a sewer inspection can check
- Hidden leaks that show up as a higher bill
Built 1960 to 1979
- Water heaters on their second or third unit
- Fixture leaks and sump pumps near wear-out age
- Basement drains that clog slowly, handled with drain cleaning
Permits, licenses and who to call
Plainville processes permits online through ViewpointCloud, and work may begin only after approval, payment and a permit are in hand. The town page lists plumbing as one permit type but does not say which jobs need one, so call inspections at 860-793-0221 extension 7175 first. You can also verify a plumber's state license, a P-1 contractor or P-2 journeyperson, on eLicense.
