"Attic Pros installed a sump pump under difficult conditions. Drained the crawl space and then installed the pump just before more heavy rains. Other companies wouldnà ¢à  à  t take the job until the crawl space was drained.. Attic Pros then sent someone the next day to finish the exterior plumbing, Very grateful for Attic Pros."

"Robert and his team saved us from an emergency with groundwater flooding under our house. I called them at 8pm and they were out within a couple of hours that night and worked until midnight to install a sump pump. They did excellent work and were very communicative about the work they were doing. I highly recommend Facilities Plumbing."

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

"**Robert was very calm, cool, and collected!!!! I got a call from my tenant at about 1p on a Sunday afternoon, that her kitchen ceiling was leaking water. I suspected there was a plumbing issue right away, and I reached out to Robert. Instantly, Robert said he would go take a look after he completed his job across town. Heroically, Robert made it there in about 30 mins and discovered the issue was a clogged pipe, and used all his tools in his belt to help me clear the clogged drain issue. Long story short -- he fixed everything before 3p 😮😮😮 Thank you Robert!! You are the man!! I will call you without hesitation moving forward!!!"

"Francisco called me right away. He was easy to schedule with. He communicated every step of the way, showed me the options and made sensible recommendations. He replaced a broken drain pipe in my garage, replaced a kitchen sink disposal and fixed the pipe in the kitchen sink."

"In and Out Plumbing was the only company to come out for an estimate on my water heater. Angel told me the water heater was fine but the recirculating pump was broken. But since the units was 17 years old, I opted to change the whole system. I had an issue with the recirculating pump ang Angel came back and made sure that I was satisfied. I wholeheartedly recommend Angel and In and Out Plumbing."

"We did not have a go-to plumber, nor did our neighbors, so we asked Angi. They recommended Steven Bailey, and it was the right choice. The job was a simple replacement of a traditional bathroom sink drain plug with a pop-up that will catch hair and, we hope, prevent future clogs. Steven was responsive, knowledgeable, and friendly, and he explained the options clearly and simply. He is an honest and skilled tradesman, and charged the minimum for the job, which was less than other quotes. Now we have a go-to plumber, and you can too!"

"Great service and quick. Plumber was very knowledgeable. Only negative was the appointment schedule. I was told between 1pm and 2pm but the plumber didn t arrive until 4pm. I think the dispatcher or owner needs to work on how to schedule clients. Plumber for me has no fault in that."

FAQs for sump pump or interior foundation drains installation projects in San Francisco, CA

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
