In Westminster, most toilet problems are fixed with a new flapper, fill valve or wax seal, and the city doesn't require a permit for a like-for-like fixture swap. Its moderately hard water can leave scale on tank parts over time. Call the number on this page to be connected with a local plumber in Westminster.

Westminster at a glance
Westminster's only water source is Standley Lake, filled with Clear Creek snowmelt and treated at the Semper and Northwest plants. The city reports total hardness of 112 to 149 ppm, about 7 to 9 grains per gallon, which is moderately hard. Housing is a mix: the median home was built in 1987, and about a third are older than 1980. Property owners maintain the sewer lateral from the house to the city main, including the tap, so a blockage beyond the toilet is a private repair.
What to do right now
- Stop the water. Turn the angle stop behind the toilet clockwise. If it won't budge, close the house main rather than forcing it.
- If the bowl is rising, lift the tank lid and press the flapper down to keep more water from entering.
- Dry the floor. A clean, dry floor makes it obvious whether water is coming from the tank, the supply line or the base.
- Test other drains. Run the tub for a moment. If it backs up or the toilet gurgles, the problem is likely in the sewer lateral.
- Check upstairs leaks from below. Look at the ceiling under a second-floor bathroom for stains.
- Call. Describe what you found so the plumber brings the right parts.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Tank refills every so often on its own | Flapper not sealing, or scale on the flush valve seat |
| Hissing that never stops | Fill valve worn or set too high, water spilling into the overflow tube |
| Puddle at the base after flushing | Failed wax ring or cracked flange |
| Water dripping from under the tank | Loose tank bolts or worn tank-to-bowl gasket |
| Bowl drains slowly, flush feels weak | Mineral buildup in rim jets or a partial clog in the trap |
| Gurgling when the tub drains | Blockage or venting problem further down the line |
Cost factors
- Part replaced: a flapper or fill valve is a short job; a wax ring means lifting the toilet.
- Scale: crusted parts and blocked jets take extra time with water this hard.
- Underneath: a damaged flange or subfloor adds materials.
- Permits: like-for-like fixture replacement needs no city permit, but relocating a fixture does.
- Drain work: a clog in the lateral calls for different equipment.
- When: evenings and weekends generally cost more.
