"The plumber spent a lot of time just trying to figure out the source of the hidden leak. He had a lot of patience. The quality of work was good as was the price. I would definitely hire them again."

"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."

"Hire them! Paul came out his with his partner and gave me the lowest quote I could find to hydro jet my area drain in my concrete driveway! Not only that, they came first thing in the morning like I wanted them to, saw the problem, cleared the drains out, and the cleaned up after themselves. They are true professionals who don’t give up on a job and make sure you get the problem 100% fixed. I would definitely recommend them for any hydrojetting service you may need."

"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."

"Very grateful for Fed! My Momâ s house had an issue with water not draining properly. Called Fed for a quote; he showed up the next morning and got to work on the issue right away. He was working by himself for awhile since it was Sunday, and had to dig through tons of rocks and roots since the land in our area are filled with stones. There were roots in the sewer line as well as buildup in the pipes; the pipes were so clogged that there was barely what seemed to be 1/8th or so of the pipe where the outgoing water/waste could flow through. He replaced parts of the line with pipes which roots would not be able to penetrate through, which gave us peace of mind as there are a lot of trees in our area. Fed and his team also added a sewer access and he replaced the filters in the toilet tanks as well. Thank you so much for helping us resolve this huge plumbing issue! Fed was honest, reliable, and friendly. Would highly recommend!"

Toilets FAQs, answered by experts

The main causes for a leaky toilet flapper include wear and tear or a broken or incorrectly installed toilet flapper chain. If your toilet flapper is torn or deteriorated, it can’t provide a proper seal to keep water from running. Meanwhile, a chain that has come loose, was moved, or just wasn’t installed right can prevent your flapper from fully closing.

While technically possible, it is unlikely that a clogged toilet will fix itself. Clogs caused by water-soluble materials like toilet paper or human waste may eventually break down in the water, allowing flow to resume. However, this can take time, and any clogs from solid objects require manual removal. In most scenarios, especially if you don't have another bathroom, it is best to fix the clog yourself or call a plumber.

Toilet handles can get stuck for a couple of reasons, but it’s commonly an issue with the chain. Remove the lid and check the chain’s connection, running from the flapper to the handle arm. Sometimes the chain gets snagged on or against another part of the tank. 

The chain might not have the right tension. For example, a chain that’s too short can make the handle feel stuck. Check that there’s some slack in the chain. Old, worn-out flappers can get stuck, too. In this case, you’ll need to see which size toilet flapper you need.

A gurgling toilet usually doesn’t mean that your septic tank is full. If waste can’t drain into a full septic tank, you’ll see water and sewage backing up into your fixtures, but the air that causes gurgling is a result of poor venting. You are more likely to have a clog in your vent stack or a damaged air admittance valve.

Yes, you should caulk a toilet to the floor for several reasons. Bathrooms are constantly wet—and if water splashes out of your shower and collects on your floor, you don’t want it seeping underneath your toilet, where it could potentially cause damage. Plus, caulk adds stability and helps prevent your toilet from wobbling.
