"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."

"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."

"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

After flushing the toilet, you should have about half a tank full of water. While the exact amount of water you’ll have will vary, you want to make sure you have enough to cover the bottom of the bowl and enough to sit above the P-trap drain. While low water in your toilet bowl can indicate a problem, too much water can also be cause for concern.

The amount of water wasted when a toilet ghost flushes depends on the cause of the ghost flushing. Leaky flapper valves tend to waste less water than a larger problem like a damaged flush valve that makes the toilet run constantly. Even if you don’t think you’re wasting a lot of water, it’s still a problem that should be fixed quickly. 

Left unattended, a leaking toilet will eventually cause water damage or mold growth. If you’re a homeowner, you can file an insurance claim for water damage. However, that can be a long and tedious process; sometimes, your insurance company may not cover the damage. Therefore, it’s always best to fix any leak you notice right away if you can.

If a toilet is not properly vented, you could experience issues like poor drainage, slow flushing, frequent clogs, malfunctioning traps, gurgling noises, and the release of sewer gasses. If left untreated, all of these issues could lead to longer term structural damage or (in the case of sewer gasses) harmful health side effects.

A standard toilet flange should fit snugly into the outflow pipe and sit level with the subfloor. Installing a new one without first removing the old one will make it impossible to form a seal and keep the toilet bowl bolted securely in place. 

However, if you’re dealing with leakage or wobbling because you’ve installed a new type of bathroom tile (making the floor taller), you may be able to avoid fully replacing the flange by opting for a toilet flange extender. Extenders typically come in kits for easy DIY installation, fit over the existing flange, and bring the drain connection higher.
