"Wilmar and Frankie did an excellent job in replacing the flange of my toilet and the pipe underneath. I could not find a match of the linoleum around the toilet. I don't even know how Fankie managed to cut the old squares so well that they could be reinstalled. He jack hammered the concrete slab underneath in a way to minimize the dust. Wilmar and Frankie covered the floor, they wore their masks, they were very pleasant to deal with, friendly, patiently explained procedures and cleaned up afterwards. I already gave my work colleagues Wilmar's number. I recommend Wilmar's service."

"Gustavo from Escamilla Plumbing responded quickly to my call for help in determining whether to repair the existing toilet. I reviewed our history of the 14 year old Toto and our current problem with the small amount of water left after flushing. He adjusted the fill valve and made adjustments to shower valve and sink faucet. Gustavo listened attentively to my existing problems and was very professional in determining his actions and I plan to use his services again."

"The Tankless Guys not only installed a new water softener system, they also put in a new tankless water heater and a new toilet. They provided excellent service. We had a range of options to choose from and Sergio and his team performed all the work in a timely manner. Sergio also answered any questions we had thoroughly. I highly recommend them!"

"We had a leaking toilet. Jose Romero of Core Plumbing responded to our request on Angi within ten minutes, and arrived at our home within twenty minutes. The problem turned out to be much more serious. The drain pipe beneath the toilet was clearly cracked and needed to be replaced. This is an older house, and there was no surprise here. Moreover, the pipe was in a narrow crawl space. Mr. Romero assessed the situation, provided a reasonable quote, and we authorized the repair. He came with his colleague Freddie the next day and did a thoroughly professional job, installing the new floor drain pipe, a new floor fitting for the toilet including a new concrete collar, and a replacement toilet all in one day. He was scrupulously clean, efficient, and we were amazed that he could accomplish this in a single day. We were very impressed with the work, and found him and his colleague straightforward, informative and pleasant. We would hire him again with pleasure. Highly recommended."

"He was wonderful! We had several issues with our toilet and system being backed up because employees/clients flushed items down the toilet over several months. Each time we had an issue, Jess came out promptly and fixed everything. He is always friendly and helpful. When a large section of our pipes needed to be replaced, he fixed it, did an excellent job AND even came out over the over a holiday weekend! We will continue to use Jess whenever we have plumbing issues!"

Toilets FAQs, answered by experts

Whether wall-mounted or floor-mounted toilets are better comes down to personal preference.

Overall, standard floor-mount toilets are less expensive to purchase and install, but they don’t offer the streamlined, modern appearance and adjustable height of wall-hung toilets. Ease of cleaning should also be considered, as wall-hung toilets are easier to clean than standard models.

The first step to clearing the air in a line is to locate the cause. This is usually a blockage in either the drain or the venting system. Once you clear the issue, flush the system by actually flushing the toilets repeatedly. This should allow the trapped air to escape, thus clearing the lines. Don’t be surprised if there is increased bubbling as the air makes its way through the system. 

Yes, you should screw your flange to the subfloor, including cement. The best way to get this done is to predrill holes into the concrete using a hammer drill and a ¼-inch concrete bit. Be careful when you’re ready to bolt your flange down, as you can accidentally crack it. You can avoid this issue by not installing the screws too deep. Or, you can opt for a flange with a stainless steel ring so you don’t have to worry about cracking the plastic.

The Thanksgiving holiday period is one of the busiest times of the year for plumbers. Both Thanksgiving Day and the day after, often called Black Friday or "Brown Friday" by plumbing professionals, see a significant increase in service requests. This is because a house full of guests, large holiday meals, and unfamiliarity with the home's plumbing can lead to clogged drains, garbage disposal issues, and sewer line backups. Outside of the holidays, the busiest weekdays for plumbers are typically Monday and Tuesday, as many people discover plumbing problems over the weekend but wait to call for service. Despite the holiday, you can rest assured that many plumbers work on Thanksgiving and Black Friday to handle the surge in emergency calls.

Some of the problems with in-wall toilets include the complex installation, which might need extra framing. It is also more difficult to access the toilet tank for maintenance or troubleshooting because it’s behind the flush button panel and in the wall. Over time, you’ll spend more on maintenance because you’ll need a plumber to work on hidden plumbing.
