Albert Nahman Services was founded in 1981 and has been serving Berkeley, CA and it surrounding areas in all their plumbing and HVAC needs. Each of our technicians went through rigorous training so we can guarantee that you will be receiving the proper service. We are also insured and supply a warranty for our parts for five years and up to twenty years on an re-piping or sewer replacement. Call us now to make your appointment!

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

"They destroyed the whole pipes that caused flooding to my neighbors. The water was off and every other day we need to go out to the street to turn it on. This company denied the responsibility but later reimbursed me for the first leak repair after employee acknowledging doing partial work. This project aims to address and fix the extensive leaks. Must be completely replaced, cause of leaks appears to be from over heating of the copper as locations are at ALL connections and bends in the pipe, too much to patch. You can contact me to this phone number: 9(16) 857-5652"

Water Heaters questions, answered by experts

Signs your electric water heater is failing include inconsistent water temperature, reduced hot water supply, longer heating times, or discolored water (rusty or cloudy). Unusual noises like popping or rumbling suggest sediment buildup, while leaks or corrosion around the tank signal structural damage. If your unit is over 10 to 15 years old and experiencing frequent issues, it may be time to replace it.

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.

Signs your water heater is about to fail include: a unit older than ten years, rust water coming from your faucets, banging and rumbling noises when you call for hot water, and leaks coming from the tank. You might also notice a foul odor when you turn on your hot water, akin to rotten eggs or sulfur. Of course, your water heater might also need replacement if your water doesn’t stay hot or takes longer to heat up.

Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty. However, even if you get away with performing the task yourself, incorrect installation, lack of a building permit, and improper repair work, regardless of licensing status, can all render your water heater unprotected by both the manufacturer's warranty and any installation warranties. 

While many older homes don’t need hot water heater expansion tanks, they’re necessary in most newer homes and are required by building codes. These tanks are required by code in areas where there are backflow preventers or pressure regulators on the incoming water pipe between the public water pipes and the water heater. However, tankless water heaters don’t require expansion tanks.
