"The actual onsite plumbing work was top notch. I'm pretty handy and can recognize excellent plumbing work when I see it. Each plumber they sent was very skilled. The reason(s) I did not give them an overall A are: - They're very busy, so getting scheduled in is not quick. - The first visit, the plumber showed up not knowing he was to install a hot water heater. So took a week or so to get them back out. Poor coordination between the sales guy I placed the order with and the service team. - Went thru 2 "advanced tech" recirc pumps before we all gave up and installed the most basic model. Turns out Valley specd this problematic pump but had never worked with it. So probably took a month before the recirc pump issues were resolved. A frustrating process, but am happy with the final result... They did try their best to make things right and to not overcharge me for "debug" time, so kudos to them. So bottom line, these guys are excellent plumbers, though pretty expensive. As always, ask a lot of questions (eg, how many of this model of pump have you installed?) to be sure you're getting what you want. After this experience, I now trust them and would definitely work with them again."

"Jesus did a great job: the house builders installed irrigation that tapped into the water main before the valve into the house, so that a leak in the irrigation system (plastic pipes) meant that we had to shut off water to the house at the water meter at the curb. We had a leak in a buried plastic irrigation pipe, and so we had to do without water until it could be fixed. Jess installed a copper pipe to split off from the main pipe and added a valve, and mated copper pipe to the irrigation plastic pipes, so that if there were a future leak in the irrigation system, it's easy to shut that off w/o having to shut off the whole house. Jesus was on time, did a great job, fixed things quickly, and I'd definitely hire him again."

"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."

"The Groundworks folks (formerly Bay Area Underpinning) applied their foundation-underpinning technology and expertise to extend to bedrock, level, square up the foundation for an extensive house remodel. I was most impressed by the young man onsite supervisor, Josh who answered all my work done, how and why questions. I wish this info was provided up front by the estimator. (My design-build remodel contractor referred this company)."

"Superior plumbing has saved the day for me on countless occasions. I hit a sewer pipe with a lawnmower because it was sticking out of the ground and hidden by overgrown grass. I didn't know what it was, and sewage started coming out a few days later. I had another plumbing company come out and quote me $30k for a sewer lateral. I then had Superior Plumbing come out since they had recently installed a sewer lateral for my parents' house for much less. They said a piece of the pipe fell into the pipe, causing it to clog. They pulled out the piece, then cut the pipe to the ground and put a concrete cap that said "sewer," so I wouldn't hit it with the lawn mower again. It cost $1700 instead of $30k! Last week, the landscapers hit the cast iron sewer pipe coming from the bathroom outside. I immediately called Superior Plumbing, and they came out in 30minutes, as luckily they were close by. They addressed the issue and returned a few days later to replace the pipe with PVS, which proved to be very affordable. I then had them return to strap pipes under the house and install a water pressure regulator, as the water pressure was 95 when it should be 60. This could cause major problems with too high water pressure down the road with burst or leaking pipes. Look no further than Superior Plumbing for your plumbing needs!"

"Look, you're not calling a company like FWDR because something happy has happened... Our refrigerator flooded our kitchen - exposing a small, long-term leak that had slowly destroyed our cabinets, drywall, and floors without for years our knowledge. We now had ourselves a water damage AND a mold problem and had no idea where to start. We were lost and stressed and didn't know who to call. I did a quick search and found FWDR because of all of their amazing Yelp reviews. One call to FWDR turned a stressful situation into a manageable project with knowledgeable support all along the way. Javier was always able to quickly and patiently answer my questions (and I had a lot of questions), he referred us to several companies to deal with prerequisite issues (asbestos and lead testing and removal), and it felt like he was there to walk us through the whole process. I can't tell you how much I appreciate the patience and consideration Javier, Santos, and Margarita showed every step of the way. They worked with the other vendors and my insurance directly to make sure that no time was wasted between services from different companies, the work was quick and thorough (proof received through testing), and every consideration was given to my family with two toddlers and small home during a pandemic - they did their very best to work around us and our day to day needs. I can't thank them or recommend them enough. Attentive, detailed, courteous, patient, thorough, and going well above and beyond in customer service - you really can't ask for more from a company you never really want to have to call in the first place!"

"It ended up all that had to be done was plug in the existing sump pump in the new house we bought, but the service person was very nice and professional, and we weren't charge for the visit. They could have told us it wasn't working and we needed a whole new system, if they were dishonest. I can't speak to their actual installation, since we were lucky enough to not need it, but if we did need a new system I would certainly have them back."

FAQs for sump pump or interior foundation drains installation projects in Sunol, 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.
