"We had plumbing issues at our new home and were unsure how and what to fix. A friend of mine recommended them to me. Michael came out and accessed our issues. He quickly addressed our problems but noticed our pressure was really high causing all those leaks to occur. He restored our pressure to a safe range and now our new home is LEAK FREE! Iâ m glad my friend recommended this company to us. I highly recommend them, Michael was very professional and knowledgeable. Will definitely recommend them to friends and family!"

"I contacted California Drains because my parent's home was completely backed up to the point where dirty water was coming out from the drains inside and outside their home. They promptly answered and booked me in the same day. They were able to contain the water from continuing to come out of the drains overnight and returned the next day first thing in the morning to get the problem fixed. Price was very reasonable, and the workers were very professional. Left everything clean and drains were completely cleared. It has been months since they came and there has not been an issue since. 10/10 will highly recommend to family and friends."

Sewer Cleaning FAQs, answered by experts

If the toilet is overflowing but there’s no clog, that’s a sign that the issue is deeper in the system, and plunging may not help. A blockage in your home’s plumbing, the plumbing vent, or even city sewer lines can cause toilets to overflow. The issue could also be the toilet itself if the filler float isn’t set to the correct height or if parts are damaged or worn out.

There is conflicting advice on whether to leave a baking soda and vinegar mixture in a drain overnight. Some sources suggest it can be effective for tough clogs, recommending that you flush the drain with warm water in the morning as part of a monthly cleaning routine. However, other experts advise against leaving the mixture in for extended periods, as its caustic nature could corrode drainpipes if used too often or left in for too long.

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.

Food grease, soap buildup, paper products, and tree roots often cause serious clogs.

Toilet paper is the only material that you should flush down toilets. Other items like wipes, paper towels, feminine hygiene products, dental floss, and medications should be disposed of in the trash. Flushing these items can lead to plumbing issues and damage to sewage systems. Grease and cooking oils should also be avoided as they can solidify in pipes, causing blockages. Proper disposal helps prevent clogs and ensures the efficient operation of wastewater treatment systems while protecting the environment.
