"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."

"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 and his team are EXCELLENT! I am an estate manager and manage multiple high-end properties for my client in Redondo Beach and the Palos Verdes Peninsula area. Sewer Boyz are our GO-TO for all things plumbing-related. We have had them work on basic leak repairs, to installing new toilets, to Hydrojetting blocked drainage lines, to replacing sump pumps! They are super professional and knowledgeable and above that, very easy to work with. If it's a more complex repair, they always make sure you understand exactly what the issue is before you make any commitments. We trust and appreciate Jonathan and in this line of business, we NEED to have knowledgable, dependable and affordable specialists like Jonathan and his team. It makes our jobs and lives easier."

Toilets FAQs, answered by experts

Yes, a toilet, sink, and shower can share the same vent. This is a common installation method that can simplify plumbing and save space. However, there are important considerations. The vent and associated plumbing must be large enough to handle the demands of all fixtures without compromising the vent's effectiveness. Additionally, the toilet should always be located downstream of all other fixtures. Because requirements can vary and space might be limited, it is essential to check your local building and plumbing codes and consult with a qualified plumber to ensure the installation is done correctly.

Most codes require 15 inches on either side of the toilet's centerline (from the wall or vanity) and at least 21 to 24 inches between the toilet and the wall in front of it. These codes ensure that your toilet is easy to use and access, even in small bathrooms. Check your local building codes for the exact measurements required. 

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.

Basement toilets don’t always need a pump. However, it is the most common setup because plumbing systems use gravity to move waste away from the home. Basement toilets often sit below the home’s main sewage system, and installing a sewage ejector pump pushes the wastewater and sewage up to the main sewer line. Alternatively, you can use an upflush or macerator toilet that breaks down the waste and pushes it straight to the main sewer line rather than via a sewer line from the bathroom.

One of the many benefits of a pressure-assist toilet is how long it lasts. You can expect a well-maintained one to last up to 30 years. That's five years longer than a standard gravity-fed toilet, so it can be a worthwhile investment if you’re willing to spend more on your toilet installation.
