"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

Hiring an emergency plumber is expensive because of the urgency and inconvenience, but there are a few things you can do to help keep costs down:

  • Minimize water damage by shutting off your water main 

  • Clean up pooling water immediately to reduce damage and mold growth

  • Avoid using fixtures if you have a clog or septic system backup

  • Verify that your plumber is licensed before hiring

  • Call a few plumbers for estimates if you can afford a short delay in getting service

Usually it’s fine to leave a toilet clogged overnight, as long as it’s not close to overflowing. In some cases, the extra time may give the clog time to work itself out. For example, if it’s caused by an excess of toilet paper, letting it sit could result in the clog dissolving and you may be able to simply flush it away by the time you wake up. 

Only let it sit though if you have more than one toilet in the home.

Technically, you can put an elongated toilet seat on a round toilet, but it’s not a good idea. Elongated toilet seats are a few inches longer than round toilets, so they will hang over the front edge of your toilet, which isn’t appealing. Additionally, an unsupported toilet seat or portion of a toilet seat is more likely to crack and shift, which could result in injury to whoever uses the toilet. Always match your toilet seat style to your toilet, or replace the toilet entirely if you’re looking to switch styles.

Replacing a toilet typically takes two to four hours. Several factors can impact this timeline, including the condition of the old toilet, flange, flooring, and pipes. If a professional discovers issues like a cracked flange, damaged flooring, leaky pipes, or a broken wax ring, the installation will take longer. Additionally, some toilets, such as wall-mounted or in-wall-tank models, are more complex to install and may require cutting into and repairing drywall, which adds to the project time. Given the weight of toilets and the importance of proper placement, it is often best to hire a professional for the job.

Yes, you can have a toilet without a septic tank. However, it will have to be a composting toilet. Composting toilets work similarly to aerobic septic systems in that the waste, which sits in a separate compartment below the toilet itself, is slowly broken down by aerobic bacteria. These toilets typically have a vent to get rid of harmful gasses with a fan, which requires a battery. You will have to dispose of waste in the toilet manually every three weeks to every three months, depending on how many people are using the toilet.
