Denver Toilet Repair, Replacement, And Installation
A toilet that runs, flushes weakly, clogs every week, rocks when you sit down, or leaks at the base. We repair and replace toilets across Denver Metro, including comfort height and ADA models, and we know which Colorado water rules apply before you buy anything. Written price before anyone starts.
Tell Us What It Is Doing
What Is Your Toilet Doing?
Six symptoms cover almost every toilet call we take. Two of them get misdiagnosed constantly, including by other plumbers.
It Runs Constantly Or Refills On Its Own
The Flush Is Weak Or Does Not Clear The Bowl
It Clogs Again And Again
It Rocks When You Sit Down
Water Appears On The Floor At The Base
The Tank Sweats And Drips
A toilet is a simple machine. Water fills a tank, a flapper drops, gravity does the rest. Almost everything that goes wrong is one of five inexpensive parts, and almost every one of those parts is worth replacing before the whole fixture is.
The exceptions are real, though. A cracked tank or bowl, a bowl rocking on a failed flange over a soft subfloor, or a pre-1994 water hog that costs more to keep than to replace. Those are replacements, and we will say so.
What we will not do is quote you a new toilet for a weak flush without first checking whether the rim jets are scaled shut, or replace a fixture without checking the water pressure that will do the same thing to the next one. Those two checks take a few minutes and they change the answer often enough to be worth doing every time.
Colorado passed a law in 2014, effective 2016, prohibiting the sale of non WaterSense plumbing fixtures in the state. For toilets that means a maximum of 1.28 gallons per flush, which is twenty percent below the federal standard of 1.6 gallons. Here is the part almost nobody mentions: Denver Water sets a stricter bar for its toilet rebate than the state sets for sale. To qualify for the rebate you generally need a model rated at 1.1 gallons per flush or lower, so a toilet that is perfectly legal to buy here can still miss the rebate. If a rebate matters to you, check the flush rating before you buy, not after. We will confirm current program terms with you before you commit.
Three Denver Conditions That Shorten Toilet Life
The first one is responsible for a large share of the toilets replaced in this city that did not need replacing.
Hard Water Scaling The Rim Jets
Denver water carries enough mineral content to slowly close the small holes under the bowl rim that direct water around the bowl, and the siphon jet at the bottom that starts the flush. As they scale up the flush weakens, the bowl stops clearing in one go, and the toilet gets blamed. It is not worn out. The jets are blocked. Descaling the rim and jet passages restores the original flush on most toilets, and it costs a fraction of a replacement. We check this before quoting a new fixture, every time.
Water Pressure Above The Code Limit
Plumbing code caps static pressure inside a home at 80 psi, and Denver’s terrain means plenty of homes run higher, especially in lower lying neighborhoods. High pressure forces fill valves to weep, which shows up as a toilet that runs briefly every few hours with nobody near it. Replacing the fill valve fixes it for a few months. Fitting a pressure reducing valve at the service entrance fixes it permanently, and protects every other fixture in the house at the same time.
Closet Flanges And Soft Subfloors
In older Denver homes the closet flange is often cast iron, and after many years under a wax ring it corrodes and the bolt slots break out. The bowl starts to rock, the wax seal breaks, and water goes into the subfloor rather than onto the tile where you would see it. Shimming a rocking toilet buys time and costs you a subfloor. When we pull a toilet we look at the flange and the floor under it and tell you what is actually there.
Repair The Toilet Or Replace It?
Most toilet problems are a cheap part. Here is where that stops being true.
| Factor | Repair Usually Makes Sense | Replacement Usually Makes Sense |
|---|---|---|
| Running toilet | Flapper, fill valve, or flush valve seal. Inexpensive parts on a sound tank and bowl. | Only if the tank is cracked or the toilet is a pre-1994 high volume model you want gone anyway. |
| Weak flush | Descale the rim jets and siphon jet. This restores most toilets to their original flush. | Descaling does not recover it, or the bowl design was a poor flusher when it was new. |
| Leak at the base | Fresh wax ring and new closet bolts where the flange is sound. | The flange is broken or corroded through, or the subfloor beneath it has gone soft. |
| Rocking bowl | Flange is intact and the bowl simply needs resetting and re-bolting. | Flange has failed or the floor under it is compromised. Never shim it and hope. |
| Repeat clogging | The trapway clears and the rest of the house drains normally. | Low volume model with a long or poorly graded drain run, where a better flushing bowl solves it. |
| Age | Post-2016 model in good condition with parts readily available. | Pre-1994 unit using three and a half to six gallons a flush. It costs more to keep than to replace. |
The Five Toilet Choices That Actually Matter
Style is your call. These five decisions affect how it performs and whether it fits.
Gravity Flush
The standard. Quiet, simple, cheapest to repair, and parts are available everywhere. Right for most homes.
Pressure Assist
Uses trapped air to force the flush. Much stronger clearing power and louder. Worth considering on a problem drain line or a heavily used bathroom.
Dual Flush
Two volumes, one for liquid and one for solid. Saves water where the household actually uses the small button. Check the full flush rating against rebate rules.
Comfort Height And ADA
A taller bowl, easier to sit down on and stand up from. Standard now in most remodels and the usual choice for aging in place.
One Piece Or Two Piece
One piece has no tank to bowl seam to leak and is easier to clean. Two piece is lighter to handle, cheaper, and simpler to replace in tight spaces.
Toilet Services We Provide
Repair through replacement, residential and commercial.
Toilets are one part of our full range of Denver plumbing services. See also faucet and fixture repair.
Heated bidet seats have become one of the most common bathroom upgrades, and they all need power. Very few bathrooms have a receptacle within reach of the toilet, and code requires GFCI protection for bathroom receptacles. So a straightforward seat swap turns into an electrical job that most plumbing companies cannot do.
We hold a plumbing contractor registration and an electrical contractor license. The water supply tee, the seat, the receptacle, and the GFCI protection are all one visit under one written price. No second contractor and no second trip charge.
The same applies to a bathroom remodel where the toilet is moving. Supply, drain, venting, and any circuits that move with it are handled by one company that is accountable for the whole thing.
