"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."

"Fast and professional. Did a nice job with the plumbing that looked great when they were done. Cleaned up the area including the trimmings of the bush they trimmed to get to the shut off valve. Would definitely use them again."

"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 was a great hire. He came and worked with my schedule and came on a quick short notice. He came for a clogged toilet and swapped my garbage disposal. The next day we clogged the toilet again and he came back within an hour to fix it again for no charge. Pricing is very reasonable and is much lower than other plumbers. I wouldn’t hesitate to hire him again. I plan to have my pipes looked at with a camera because I can’t have this keep happening."

"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

Yes, and no. Your shower, toilet, and sink all connect to the same main drain, but the secondary drains going from each fixture to the main drain are usually separate. This isn’t always the case—especially in older homes—but since toilets contain black water and showers, tubs, and sinks have grey water, toilets are more regulated and come at a greater risk of contamination. It’s best to keep these drains separate using individual waste collection for this reason.

The toilet should rest 10, 12, or 14 inches from the back wall. As for other clearances, 15 inches is the minimum distance from the flange to any side wall or nearby fixture, including the shower, tub, and sink. Modern codes also require at least 24 inches of clear space in front of the toilet.

Ensuring your toilet will fit starts with measuring the rough-in, but there are a few other factors to consider. The toilet tank's height and the toilet's depth should fit comfortably within the bathroom’s current setup. When considering depth, look at the walking space around the toilet to ensure it fits in the bathroom.

Yes, you’ll need to replace your toilet’s wax seal any time you move the toilet. This is because movement of the toilet will break the seal, rendering the remaining wax useless. Thankfully, replacing a wax seal is fairly easy, and the seal itself only costs $2 to $10 at most home improvement stores.

When replacing a wax seal you typically also have to replace the closet bolts that secure the toilet to the flange. These are usually about 2.5" - 3" long and have to be cut once the toilet is secure. Cutting them usually makes them too short to reuse.

If you notice that your toilet is leaking puddles near the base, the leak is coming from your toilet bowl, and the water could be unsanitary. This is a situation that needs to be dealt with immediately—call a nearby plumbing repair pro right away. A contained leak from tank to bowl is not as urgent a situation, but it could be raising the cost of your water bill—have it looked at as soon as you can.
