"Ryan was perfectly on-time and was a plumbing scholar and a gentleman. We had a simple drain replacement under a new sink. Going to Western saved me at least another day of trying to figure out proper parts and doing the install myself, and it also saved my wife's ears from hearing my salty language."

"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."

"Capped an old water connection in my laundry closet and closed it into the wall, as well as changed the connection box around the drain hose to make it more flush with the wall. Looked like the water connection was never there when they got done with it, and the connection box/drain hose looked great as well. Definitely recommend!"

"Great! Beautiful straight walls with split face block and topped with brick. Very helpful with ideas for a design that will work with my home, clean, friendly and professional. Also poured driveway and little concrete bridge over a wash at the back of my home with tunnel drain so water still gets through. Highly recommended!"

"Robert and his crew did a great job installing a concrete walk in my side yard. They had some challenges working around our existing irrigation valves and pipes, but they took the extra time to do it right. After installing the concrete Robert found an area which was not draining fully and he put in extra time and effort to fix the problem area. Robert communicated with us during the project and was very professional. I would recommend Robert Garcia Concrete!"

Customers say: True professional

"We are thrilled by the results! Mike and his crew took out 10 boxes of dirt from a hill in our back yard all manually! They then installed a 50 x 4ft retaining wall (fully permitted) on the hill. After that poured a 60 x 10 concrete deck and steps to our new upper deck that now overlooks the pool. They then covered the new wall and existing lower wall with new custom colored stucco. We have now doubled our backyard space and for the first time in 12 years be proud to show off our backyard!

Foundation Drain Installation FAQs, answered by experts

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

The regulations around whether drain pipe installers need to hold licenses or certifications differ based on where you live and the type of drain pipe installed. Municipalities have varying rules and regulations about who can and can’t perform plumbing work. However, we recommend hiring a certified plumber to install or modify your drain lines. Licensed plumbers will perform a high-quality, professional installation, which translates to a lower risk of clogs and leaks in the future. Use Angi’s state licensing tool to confirm the license status of your potential plumber before hiring them to install your drain pipe.

Your sump pump will discharge water through a discharge line or pipe. The discharge line should be placed at least 10–20 feet from the foundation to avoid any issues.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.

The difference between an ejector pump and a sump pump lies in their purpose and design—an ejector pump functions to remove liquid gray water and soft solid sewage waste from your home. If you have a laundry room or bathroom in your basement, an ejector pump for your sewage tank prevents sewage from backing up in your washing machine or bathroom’s drains.

A sump pump is designed to remove excess groundwater that may enter your home, either due to flooding or periods of heavy rain.
