"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."

"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."

"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

A toilet flange secures your toilet in place to the floor, and connects your toilet to the drain pipe that carries its contents to the sewer. Obvious signs that your flange needs replacement include when it can’t keep up with these two functions. If your toilet rocks back and forth or you see leaks coming from the bottom of your toilet, it’s time for a replacement. Other signs that your toilet flange is broken or faulty may include loose tiles or soft flooring around the toilet, and sewage smells.

The most common toilet repair is dealing with clogs, followed closely by replacing a worn-out flapper. While clogs can happen anytime in any toilet, they most commonly occur with older toilets that have smaller diameter clearances and often empty into smaller diameter sewer connections. Because toilet flappers only last a few years, they are next in line for the most common toilet failures.

For best results, you should remove the toilet in a bathroom before removing tile or installing new tile. If you don’t remove the toilet, it will be harder to fully waterproof the tile around the toilet, which could increase the risk of mold growth or plumbing leaks. If you have trouble removing the toilet, hire a plumber to help.

If you don’t replace a toilet flapper, your toilet tank will continue to empty and fill repeatedly, wasting water and running up your utility bills. Checking the flapper is a good first guess when dealing with a constantly running toilet. However, if these problems continue after replacing the flapper, you may need to hire a plumber to check and fix any bigger problems. 

The average cost to hire a plumber is typically between $45 and $200 per hour, with a common average rate around $125 per hour. This cost can vary based on your location, the plumber's experience, and the complexity of the job. Rates are often broken down by experience level: an apprentice may charge $45 to $90 an hour, a journeyman $60 to $110 an hour, and a master plumber $80 to $200 an hour. While hourly rates are standard, some plumbers may charge a flat fee for routine projects or offer project-based pricing. It's also common for plumbers to charge a minimum service or trip fee. For reference, some typical flat-rate costs for common jobs include: drain unclogging ($220), leaky faucet repair ($270), burst pipe repair ($400), toilet repair ($300), and water heater repair ($600). Note that these rates are for standard service hours; emergency, holiday, and after-hours calls will cost significantly more.
