Toilet Repair & Replacement in San Antonio, TX

Repairs & New Installations

Toilet Repair & Replacement

A running toilet, a leak at the base, or a toilet that clogs all the time. We fix it, or install a new one that works right.

Every Toilet Problem, Handled

Toilets get used more than any other fixture in the home, and when one acts up, you notice fast. MC 1 Plumbing repairs and replaces toilets throughout Greater San Antonio, from a flapper that won't seal to a full replacement with a new, efficient model.

The most common problems are a toilet that runs constantly, one that rocks or leaks at the base, weak or incomplete flushes, and frequent clogs. A running toilet can waste a large amount of water, and a leak at the base often means a failed wax ring that can damage the subfloor if it's ignored.

When it's time to replace, we can install the toilet you've chosen or help you pick one, including upgrading from older builder-grade models. Every job is backed by a licensed Texas Responsible Master Plumber (RMP M-43246) with 30 years of experience.

Small Toilet Problems Get Expensive

Leaks and running water add up quickly, both on your water bill and under the floor.

💧

Stop the Running

A constantly running toilet wastes water every hour. We stop it.

Protect the Floor

A leak at the base can rot the subfloor. We replace the seal properly.

Better Flushing

Weak flushes and frequent clogs usually have a fixable cause.

Upgrade Options

Replace an old or builder-grade toilet with one that performs better.

Leaks at the Base Don't Stay Small

When water shows up around the base of a toilet, or the toilet rocks when you sit on it, the wax ring or flange beneath it has usually failed. That seal keeps water and sewer gas where they belong. Once it fails, every flush can let a little water seep into the subfloor, and the damage isn't visible until it's serious.

We pull the toilet, inspect the flange, replace the seal, and reset the toilet securely so it doesn't rock. If the flange itself is broken or corroded, we repair or replace it so the new seal lasts.

For toilets that run or refill on their own, we replace worn flappers, fill valves, and flush components. If a toilet is cracked, very old, or constantly needs repairs, replacement is often the better long-term value.

Toilet Repair FAQ

Why does my toilet keep running?

Usually a worn flapper or fill valve. It's one of the most common repairs we make, and it stops wasted water right away.

There's water around the base. What does that mean?

Most often the wax ring or seal has failed. It should be fixed promptly, because water can seep into the subfloor with every flush.

Should I repair my toilet or replace it?

If the toilet is in good condition, repairs are usually the best value. If it's cracked, very old, or keeps needing work, we'll recommend replacement.

Can you install a toilet I already bought?

Yes. We install customer-supplied toilets and replace the seal, supply line, and shutoff valve as needed.

My toilet clogs all the time. Is it the toilet or the drain?

It can be either. Older or low-performing toilets clog more often, but frequent clogs can also point to a drain line problem. We'll figure out which.
