"Can not imagine a better response, starting with my call for assistance, response time and how the technician, Tad methodically diagnosed the problem. We have an obscure kitchen fixture that required service in Feb 2019. Under warranty the problem was easily diagnosed by me, a problem possibly caused by me and a replacement part sent and installed by Albert Nahman team. Problem: I broke the faucet cartridge. Current Problem: restricted hot water flow in this kitchen sink only. Turns out the new cartridge part is now malfunctioning. I called and Tad arrived taking a step by step approach ruling out possible causes: a clog here or there, build up of sediment, or blockage in the lines or cartridge. The company that sells the product got on the phone with Tad and they collaborated on the problem and the tech person gave Tad one more thing to try. After the collaboration it is agreed, problem persisted and therefore that new cartridge part is now malfunctioning and will be shipped free of charge in two days. Thanks to all, who made this possible and I trust we will have Tad here again soon to finalize this fix. BTW, cost of service was less than expected given going rates for such a call lasting in excess of one hour. Another comment, spending time with Tad during the repair was a pleasure to have him explain, collaborate, listen and just chat. Questions on who to call next time, no question who I will call next time. I have read criticism of costs: In the Berkeley area "How much does it cost to hire a plumber? Some plumbers have a minimum fee for a service call. They might charge anywhere from $175-250 to come out and give you a consultation. Plumbers may give you a general service rate of $128-148 per hour when there are a lot of unknowns about a project and they aren't sure how long it will take. Some charge a flat rate for their plumbing services. For example, you may get charged $175 for a sink or drain cleaning, while toilet installation costs $500." Today costs are upfront, same as charges in Feb, $69 to arrive and assess the problem. Here in excess of one hour for $129 minus $25 coupon, total charge $173. I am ok and I expected these costs. If I was in Philly, where I grew up, I could call an uncle or cousin and get a better rate, a family rate. This is going rate for our area."

"I had water damage to the ceiling of my garage. Vicente provided evaluation and written estimate in one visit with attention to details and my customer satisfaction. He took the time to verify my plumbing problem by video taping my water leakage of my bathtub drain pipe with his phone through the broken spaces in the ceiling. He returned the next day with Eduardo, assistant, to complete repair with pipe replacement of old bathtub drain pipes. I was impressed with Vicente's respectful, honest, confident, and professional demeanor with attention to customer satisfaction and service. Vicente exceeded my expectations with exemplary work. Bonus: I discovered afterward that Vicente had fixed my slow flowing sink faucet next to bathtub without request or charge. I would request Vicente again for all my plumbing needs in future. Thank you Vicente. You are special!"

"**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!!!"

"The plumber arrived on time, assessed the work to be done and the setting, and provided us with an estimate for five separate options. He thought he needed help, but no one was available from his company. So he went out to the plumbing supply store to pick up supplies we had not provided (we had purchased all of the replacement faucets, and two of the four shutoff valves). He worked diligently and finished the project by late afternoon. Our only complaint was that the plumber did not set the drain plugs properly. I spent about an hour resetting the “open” position so that liquids would drain properly."

"My lovely home in Saratoga required a water re-pipe. Upon giving TJ plumbing, a call, a clean, looking young man arrived at my doorstep. He was very friendly and professional. He introduced himself as TJ and proceeded to kindly asked me to give him a brief tour of the house for his assessment. Upon the end of the house tour, he proceeded to ask me about my expectations. I told them that I was just looking to replace my pipes. TJ began to present the several options that were available for my new plumbing pipes. His office included, standard replacement, addition of a softener, a relocation and upgrade of a water heater, and also the different options of materials ranging from PEX, thin-copper, and thicker-copper (apparently there’s a difference in copper, which I never knew) TJ came across very knowledgeable and quite capable of performing the task at hand. I decided to go with him and to commence the work. He was very professional, he took care of my wood floors by creating a walkway with tarps, wrapped plastic around furniture and areas of the living room, bedrooms, and dining rooms, where he intended to work to minimize dust and debris. He consistently kept me updated as to the progress of the work, and gave me a Fair Notice as to when he will be turning off the water. This gave me an ability to use any of my facilities before he disabled them. While working under the crawlspace, he also found an issue with my drain pipe, which was cracked and seeping sewer waste in my crawlspace. For a reasonable price, he took care of the cracked drain pipe on top of all the work he was currently working on. His pricing also included repairing the drywall that had to be cut open. He is not the “I can do everything type of plumber” because for purposes of the drywall, he hired a professional drywaller to repair the walls, which seemed as if they were never opened. I was extremely happy with the end result, and with the quality of work that he provided. I personally decided to include the upgrade and relocation of the water heater to an outdoor tankless. This gave me the ability to reclaim space in my garage, which I can now use to hoard more unnecessary junk. I highly recommend TJ plumbing for any plumbing needs around the home. I would at a minimum give TJ Plumbing a call, to assess the work to be performed. Thank you, TJ plumbing for your professionalism and hard work! -Tony-"

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