Denver Toilet Repair And Installation
Most toilets we are called to replace did not need replacing.
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.

Before You Buy
Most Toilets Get Replaced When They Did Not Need To Be
And a lot of the ones that do get replaced end up being the wrong model for the room they went into.
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 Rules You Should Know Before Buying
Every Toilet Sold In Colorado Must Be WaterSense Certified
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.
Why Toilets Fail Here
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.
01
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.
02
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.
03
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.
The Honest Answer
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. |
Choosing One
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.
Buying Your Own
Check The Rough-In Before You Buy A Toilet
The rough-in is the distance from the finished wall to the center of the drain, and it is usually 12 inches but can be 10 or 14 in older Denver homes. Buy a 12 inch toilet for a 10 inch rough-in and it will not fit, no matter how good the toilet is. Measure before you order, or call and we will confirm it for you. We install customer supplied toilets and we will tell you about a fit problem before the water goes off, not after.

What Denver Homeowners Say
Descaled the rim jets and the flush came back like new. Two other companies had quoted me a whole new toilet.Placeholder review, Congress Park
Found the flange had corroded through and showed me the soft subfloor before touching anything. Fixed it properly instead of shimming it.Placeholder review, Englewood
Added the outlet for the bidet seat and did the plumbing on the same visit. I was expecting to have to book an electrician separately.Placeholder review, Highlands Ranch

Where We Are Different
Adding A Bidet Seat Needs An Outlet Behind The Toilet
Almost no bathroom was built with one. We hold both licenses, so the receptacle and the plumbing happen on the same visit.
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.

Questions
Frequently Asked Questions About Denver Toilets
Why does my toilet keep running?
Usually a worn flapper that no longer seals, or a fill valve that has started to weep. Both are inexpensive parts. If a new fill valve solves it for a few months and then it returns, the underlying cause is often water pressure above the code limit of 80 psi forcing the valve open. Fitting a pressure reducing valve at the service entrance fixes it permanently and protects every other fixture in the house.
Why is my toilet flushing weakly?
In Denver the usual cause is mineral scale closing off the rim jets under the bowl rim and the siphon jet at the bottom of the bowl. As those passages narrow the flush loses force and the bowl stops clearing in one go. It looks like a worn out toilet and it is not. Descaling the rim and jet passages restores the original flush on most toilets at a fraction of the cost of replacement, which is why we check it before quoting a new fixture.
Should I repair my toilet or replace it?
Most toilet problems are a flapper, a fill valve, a flush valve seal, or a wax ring, and all of those are worth repairing on a sound bowl and tank. Replacement makes sense when the tank or bowl is cracked, the closet flange has failed and the subfloor has softened, or the toilet is a pre-1994 model using three and a half to six gallons per flush. Our plumber tells you which one you have before quoting either path.
What toilets are legal to install in Colorado?
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, twenty percent below the federal standard of 1.6 gallons. Any toilet currently sold here meets that. Older homes often still have 1.6 gallon models from the nineties, or pre-1994 units using far more, and those are legal to keep but not to buy new.
Does Denver Water offer a toilet rebate?
Denver Water runs a rebate program for high efficiency toilets, and its threshold is stricter than the state rule for sale. To qualify you generally need a model rated at 1.1 gallons per flush or lower, rather than the 1.28 gallons the state requires. That means a toilet you can legally buy in Colorado may still fall short of the rebate. Program terms change, so we confirm current requirements with you before you commit to a model.
My toilet rocks when I sit on it. Is that serious?
Yes. A rocking bowl means the closet flange has failed, the bolts have pulled loose, or the subfloor underneath has softened from a slow leak. Every rock breaks the wax seal a little more and sends water into the floor rather than onto it. Shimming it hides the movement and lets the damage continue. When we pull the toilet we inspect the flange and the floor beneath it and show you what is there.
What is a toilet rough-in and why does it matter?
The rough-in is the distance from the finished wall to the center of the drain. Twelve inches is standard, but older Denver homes are sometimes ten or fourteen. A twelve inch toilet will not fit a ten inch rough-in regardless of quality or price. Measure before ordering, or call and we will confirm the dimension for you before you buy.
What affects the cost of a toilet replacement in Denver?
Five things move the number. The model you choose, since gravity, pressure assist, dual flush, and comfort height sit at different levels. Whether the closet flange is sound or has corroded through and needs replacing. Whether the subfloor beneath it has softened from a slow leak, which adds carpentry. Whether the rough-in matches a standard twelve inch model or needs an offset. And whether the supply line and shutoff valve are old enough to replace at the same time. We inspect all five before quoting and put the price in writing before any work begins.
Will you install a toilet I bought myself?
Yes. We install customer supplied toilets regularly. We will tell you before we start if the rough-in does not match, if the bowl shape will not clear the vanity or door swing, or if the flange needs work first, so you have time to exchange it rather than finding out with the water shut off.
Can you install a bidet or bidet seat?
Yes, and this is where holding both licenses matters. A heated bidet seat needs a receptacle within reach of the toilet, and code requires GFCI protection for bathroom receptacles. Most bathrooms do not have one. We handle the supply connection, the seat, the new receptacle, and the GFCI protection on one visit under one written price rather than sending you to an electrician.
How long does a toilet replacement take?
A straightforward like for like replacement is usually a same day job of a couple of hours, including a fresh wax ring and new supply line. If the closet flange is broken or the subfloor around it has water damage, that adds scope. We show you what we found before doing any additional work.
