"Kirk was able to correct both of my plumbing issues very quickly...a faucet that had very little water coming out and a slow draining sink. He also checked the water pressure at the front of the house..it is a bit high so we are going to decide the next step on this. I am always pleased at the communication from Valley Plumbing and most of all I am pleased with Kirk's professionalism, courtesy and skill in solving my problems. Highly recommended. I felt the price was fair and appreciated the senior discount."

"Excellent. Two employees did the job. Nice guys. Very polite and they were able to complete a complex job on time. I would definitely hire this company if I ever needed a plumber. The guy who sold us on the job was extremely knowledgeable which is why I selected this company."

"They did a number of things. Braced and restrapped water heater and ran copper line for pressure relief to outside. Unclogged master toilet and reseated. Bolted down second toilet. Reconnected clothes dryer vent. Repaired air gap/garbage disposal and drain line under kitchen sink, crawled under house and remove galvanized pipe straps and replaced with nylon pipe clamps. I was a contractor and used to do this work, o an very critical. They did an outstanding job. Went the extra mile several times. I was expecting a bill for a higher amount but they stuck with their estimate. I recommend them highly and would use them again!!"

"The team I worked with at BAU was great. I hired them to repair some minor vertical and horizontal foundation cracks that were found in a recent general home inspection. Everyone who came out was upbeat, professional, punctual, thorough, and highly detailed. Hunter came out first to check the entire foundation and give a free estimate. They then split the work up into two dates, and each crew was great. Michael and James came out first for the initial round, and then Alexander and Gabe came out to wrap up the last few areas. The guys were always on time, which is greatly appreciated. Both repair teams also did their own additional checks of the surrounding areas, also greatly appreciated. They were also able to provide before and after pictures, and were respectful of the property."

"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!"

"Overall they did NOT do what they were paid to do. 1) They were paid $25,000 to document and remove the contents and on numerous occasions they opened a drawer and took one picture, or they missed an area entirely. I would say about 30% of the contents were documented in this way. Their job was to document everything so we could file a comprehensive claim. I personally spent over 150 hours working on the contents inventory to make up for their shortcomings. 2) They were paid an additional $5,691.95 to clean some of the contents that could be salvaged. Numerous items, we can only document 14 of them, are missing from the cleaned contents totaling a value of over $7,000. WDR's response was oh we made a mistake and disposed of those items and you will be reimbursed by the insurance company for their value (of course depreciated) so no harm was done. Of course there is harm!! These items had not only material but sentimental value! We lost everything in my parents home of 50+ years and they just threw the things away. Very Very unprofessional. 3) In the boxes of items that were cleaned and returned we have found items that were never ours, how many people have they switched or lost items on??"

"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."

"Few week ago I realized that I have a hot water leak somewhere in the lines because the water was not getting as hot as it use to, the main burner of the water heater was running all the time and water meter needle kept spinning even if all the taps in the house were closed. And finally high PGand E bill showed up for excessive gas utilization. I was worried how to find the leak since there was no seepage or dampness visible anywhere in the house. I called around several plumbers to get an idea what to do. They all told me that the leak has to detected and pin pointed first before any repair can be done. After talking to 4 different plumbers on the phone I decided to go with Savior Plumbing. I spoke to Tom, owner of the company, and he sent in his manager Darrell to examine the house plumbing and give suggestions and preliminary estimate. Darrell arrived on time and thoroughly examined the problem. Darrell informed me that since my house is on the slab and I have no attic due to vaulted ceilings; re-piping of the hot water line will be very expensive and difficult task. He recommended to pin point the leak and then dig a hole by breaking the concrete and patch the leaky pipe. Darrell recommended Steve from "Independent Leak Detection" to detect and pin point the leak. Steve arrived on time and by utilizing specialized equipment for underground leak detection mapped out all the pipes underneath the slab in my house. He then pin pointed the leak in my atrium, what a luck !!! The leak could have been very well in my bed room or living room. I was relieved immensely that the interior of the house does not have to be dug out. Next, Tom came in to give the estimate and schedule the work. Tom estimated 4 - 5 hours of work including cutting the bricks, breaking the concrete, digging the dirt, patching the pipe and the putting the dirt back in. Next Monday he sent in one of his experienced plumber, Mike. Mike arrived on time and worked with great efficiency. He finished the 4 - 5 hours job in only 2.5 hours and cleaned up all the area after finishing. He also replaced a leaky pipe on water heater. The total cost was $383.49 plus $250.00 for leak detection. The job was done professionally and I am very pleased with Tom and his workers. I now just have to put the new bricks to close the hole; I think I can do that on my own."

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