Toilet Repair

While toilets often outlast most other plumbing fixtures in the home, they do fail and may need to be repaired or replaced. We know that a working toilet is essential to a happy home or office so we stock parts on our vans for common toilet brands and part replacements.

Common toilet calls we get include:

• Toilet runs continuously
• Water leaks from the floor when the toilet is flushed
• Water level in toilet tank or toilet bowl is low or will not fill all the way
• Toilet is difficult to flush or will not flush at all


How to Detect if Your Toilet Tank is Leaking

Toilet tank leaks waste water and cause higher water bills. If you suspect your toilet tank is leaking, a simple do-it-yourself home toilet leak test can detect if your toilet tank is leaking water into your toilet bowl.

Following these steps to test if your toilet tank has a leak:

Step 1. Remove the toilet tank lid and add a small amount of red food coloring to the tank’s water.
Step 2. Replace toilet tank lid and do not use toilet for at least an hour.
Step 3. After an hour, check to see if the water in your toilet bowl has any signs of the red dye. If it does, then the water in the tank is continuously leaking into the toilet bowl. Be sure to flush and clean your toilet immediately following the test to prevent dye stains.

Most toilet tank leaks can be fixed by replacing your tanks internal parts. To test for a hairline crack in the toilet bowl, use the same procedure but put the dye directly into the toilet bowl.

Some Brands We Work With!


You’re in Good Hands

“One stop plumbers came out on Christmas Eve and saved Christmas!!! Our lovely daughter decided to flush her fake cell phone down the toilet. Our plumber was able to get it out in 15 minutes and only charged us $99 when they quoted $150 over the phone. The gentleman was very polite and timely. I would definitely recommend them!”

“I used this company to install a new toilet. They were very reasonably priced, came out at my first available day, and did the install very quickly and professionally. I will use this company again when I need plumbing services in the future! Thank you”

Brian C.Toilet Repair, Rancho Cucamonga, CAYelp

“This company is excellent and prices are reasonable. Had 2 plumbing problems within a 1 month of each other. First to replace water heater and the other to remove object from toilet, my grandson felt had to go there. Travis and Michael were great, both very professional and knowledgable. Worked fast and cleaned up after the work was done. I will only use OneStop plumbers and would recommend them to my family & friends. Thanks guys, you were great :)”

OneStop Plumbers is a great business.  I have used over three times them for your basic shower clogs due to long hair and toilet issues.  Leahs response is top notch!!  They arrive within the time frame or even earlier always with a phone call.  I have recommended them to family and friends.  This is how a successful business should be operated!
Highly recommend OSP!!!
