"The technician arrived at the start of the 2 hour window. On time! Very professional. Explained options for dealing with my toilet leak. I chose to replace the toilet and gave him guidlines for the new toilet. He went to Home Depot, acquired the toilet returned promptly and installed it in a timely manner. After which he broke down and explained the itemized charges. After paying for the work thru my credit card, I received an e-mail summary right away...One major concern that I had in hiring Western Rooter & Plumbing was that their technicians had been vaccinated for Covid 19. I had been referred to Western earlier this year by my condo HOA for a common area leak repair in my unit. I was assured by the dispatcher that the technician coming to my condo was vaccinated against Covid. So when I had this toilet leak problem 6 months later that I had to pay for, out of a multitude of plumbing companies, I went back to Western Rooter & Plumbing after receiving the same assurance."

"The technician was early, polite, and efficient. The price was fair and the work fixed the problem. He did offer to run a camera down the drain line, but every plumber I've ever hired has done that and he didn't force the issue. An all-around terrific experience."

"Jonathan and his team are EXCELLENT! I am an estate manager and manage multiple high-end properties for my client in Redondo Beach and the Palos Verdes Peninsula area. Sewer Boyz are our GO-TO for all things plumbing-related. We have had them work on basic leak repairs, to installing new toilets, to Hydrojetting blocked drainage lines, to replacing sump pumps! They are super professional and knowledgeable and above that, very easy to work with. If it's a more complex repair, they always make sure you understand exactly what the issue is before you make any commitments. We trust and appreciate Jonathan and in this line of business, we NEED to have knowledgable, dependable and affordable specialists like Jonathan and his team. It makes our jobs and lives easier."

Toilets FAQs, answered by experts

The cost depends on the parts, labor, extent of damage, and whether extensive plumbing modifications are required. Typical repairs cost $150-$300.

To drain a broken toilet, place towels or plastic sheeting around the base in case of splashing or overflowing. Next, shut off the toilet’s water supply, usually via a valve on the wall behind the toilet. Begin flushing the handle to remove as much water as possible from the tank and the bowl. Don’t flush the toilet if it’s clogged, though. From there, use a large sponge to soak up any remaining water and wring it over a bucket. 

While a leak may seem small, even a gentle trickle of consistent moisture can lead to mold problems in your bathroom. Make sure you know how to check for mold if your toilet has been leaking for a while. Pooling water by your toilet also poses a risk for someone slipping on the slick floor of your bathroom. Finally, a leak of any size can lead to water waste that increases your water bill.

Options include standard, dual-flush, and low-flow models. Choose based on water efficiency and design preferences.

Your toilet handle might not come back up if the nut is loose or the bolt threads are stripped. Try to tighten the mounting nut and wrap plumber’s tape around the handle bolt to fix stripped threads. It’s possible the handle was improperly installed. If that’s the case, you can use the instructions above to correct the handle’s position.
