Let's Get Your Toilet Running Right

Our Professional Toilet Repair Services

While you may not know exactly what needs to be repaired or replaced on your faulty toilet, the team at Mammoth Plumbing surely will. Give us a call today to schedule your toilet repair service and we’ll inspect your toilet for the following issues:

Flapper Replacement

The flapper is responsible for sealing the tank and allowing water to flow into the bowl during a flush. A worn or damaged flapper can cause constant running water and should be replaced.

Fill Valve Replacement

The fill valve controls the water level in the tank. If it’s not functioning correctly, you may experience issues with water levels, fill noise, or slow tank refilling.

Flush Valve Repair or Replacement

The flush valve, also known as the flush seal, can deteriorate over time, leading to leaks or incomplete flushes. Repair or replacement is necessary to maintain proper flushing.

Wax Ring Replacement

A deteriorated wax ring can result in leaks at the base of the toilet. Replacing the wax ring and resetting the toilet can resolve this issue.

Toilet Handle Replacement

A broken or malfunctioning toilet handle can prevent flushing. Replacing the handle is a straightforward repair.

Clog Removal

Stubborn clogs in the trap or drainpipe may require snaking or plunging to restore proper flushing and drainage.

Leak Repair

Leaks around the base of the toilet or from the tank-to-bowl connection should be repaired promptly to prevent water damage.

Tank or Bowl Replacement

If the tank or bowl is cracked or damaged beyond repair, replacement may be necessary.

Seal and Gasket Replacement

Replacing seals and gaskets around the tank, bowl, or water supply connection can prevent leaks.

Fill Tube Replacement

The fill tube delivers water to the bowl during the fill cycle. A damaged or improperly positioned fill tube can result in inconsistent water levels and flushing problems.

Pressure-Assist Repair

Pressure-assist toilets may require repair or replacement of their pressure vessel if it’s damaged or not holding pressure.

Anti-Siphon Valve Replacement

The anti-siphon valve prevents water from flowing back into the main water supply. If it’s not functioning correctly, it may need to be replaced.

Excellent4.6 Based on 23 reviews from review us onAngel Fultz-SmithAngel Fultz-Smith ★★★★★ Mammoth Plumbing has been my go-to plumber for the past few years. They have solved minor problems related to clogs, sinks, and the water heater, and they also installed the gas line for a stand-alone home generator. Their pricing is competitive and reasonable, and I trust them to be honest when assessing a problem. Jon and his team conduct their business with integrity and transparency, and I have recommended them to friends and clients over the years. They're fantastic and I cannot recommend them enough.Response from the ownerThank you ms. Fultz-smith for the review it's always a pleasure working for such great clients, thanks for the referral.

Highly recommend them. There should be a 6th star.Update. We had some serious under-slab plumbing issues. They were able to accurately diagnose the issue where other companies had failed. They put everything back as it was, and even added some smart clean outs and tie-ins for future plans. The most impressive part was though was how much the hustled to get it all done. They even sent my wife flowers when they learned she had gone into labor. Absolutely amazing.Response from the ownerthank you Mr. bower, we really appreciate your business! JohnJohn ★★★★★ I just wanted to send you a big shout out for great service. Jimmy came out to look into my washing machine waste line which also has my drain from the AC unit and it had been slightly overflowing. I first used a safe drain opener to possibly open the line, but in addition wanted to have it looked at to make sure everything was okay. He did an outstanding job scoping the line and found just a small amount of sediment on the walls. I just wanted to let you know that I will highly recommend your company to anyone needing quality professional plumbing work done!JohnResponse from the ownerThank you so much for your business and your patience, it was a pleasure working for you, I will pass this letter on to jimmy.

Definitely will use them again and please give Ron some recognition!Kevin MellorKevin Mellor ★★★★★ West UniversityGary LegerGary Leger ★★★★★ I had called a different company that charged a big service fee and did nothing to fix the problem. However mammoth came out fast and on time and readjusted the work I had done and got the water heater started in 10 min. Michael was great. I will used them before anyone else in the future. Awesome company!Response from the ownerthank you for your review Mr. leger, we greatly appreciate your business. Carey TiseCarey Tise ★★★★★ I had great service, Mammoth called before coming out and gave me a window of when they would be there so I could plan. They arrived as promised and installed a new hot water heater in the upstairs attic. They disposed of the old hot water heater so I did not have to deal with it. Their pricing was great and billing was the amount they promised, with no hidden charges. Great job!js_loader
