"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."

"Good efficient work, showed up on time, clean, courteous workers. They gave me one choice for a replacement toilet to install the next day, so in the meantime I looked up the brand and model and found it was one of the cheaper toilets on the market. I called next morning and they offered me a better one at the same price. I should have done the same with the water heater they replaced. After it was completed I found pretty poor reviews on it. SoCal does give a 3 year warranty on labor, and manufacturer 6 years, so hopefully it will last longer than thatâ ¦ Just beware- probably with any plumbing company- Find out first what the reviews are on the plumbing fixture they're giving you before you sign off on it. As long as you do that this seems to be a reliable plumbing company to use."

"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 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."

Toilets FAQs, answered by experts

While you don’t have to run out and immediately buy a new toilet at the first sign of a clog, if the toilet keeps clogging because it’s a low-flow or poorly designed model, a new toilet may be the way to go. If your toilet keeps clogging, you can try using less toilet paper, adjusting the fill valve, checking the toilet vent pipe on the roof, and using a toilet auger to make sure nothing is stuck in the pipe or trap.

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.

Sealant doesn’t need to be applied to the bolts, but it can be a good way to stop an active leak in the moment. However, don’t rely on it as a cure-all; instead, make sure to fix the problem at the source by changing or tightening the bolts. 

If you do use sealant, make sure to spread it thickly and evenly across the bolts and the tank's porcelain.

No, you can’t convert a gravity-flush toilet to a pressure-assist toilet. Pressure-assist toilets include a tank-within-the-tank, and a standard gravity-flush toilet doesn’t have a capability to include the additional tank. If you want the benefits of a pressure-assist toilet, you’ll have to make the investment in a new one. 

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.
