"Called this company for their $77 dollar, which they advertised with a flyer, for a tune-up and cleaning for my heating system. They are a Hayward company and I was told that our Castro Valley home was not in their service area. I bet if I called to buy a new heater they would be out in a day."

"10/6/2024 - Ongoing Toilet Leak Issue – Unresolved Since February Dear Albert Nahman Plumbing, I hope this message finds you well. I am writing to express my extreme frustration regarding the ongoing toilet leak issue that has yet to be resolved, despite numerous attempts to rectify it. The problem began in February 2024, when my toilet started leaking and refilling its tank every 2 to 4 hours. Since March 18, 2024, I have had five appointments with your team to address this issue. I have paid a total of $545 for a new canister flush valve and a new toilet fill valve, yet the toilet continues to leak exactly the same way it did before. What is particularly disheartening is the lack of communication since August. I have repeatedly tried to reach out via email and phone, but my messages have gone unanswered (August to October). I chose your company based on your good ratings and the assumption that I would receive quality service from a licensed plumber. Unfortunately, my experience has been quite the opposite. I would appreciate a prompt response to this matter and a clear plan for how we can finally resolve the leak. Thank you for your attention to this urgent issue. Sincerely, Andreas"

"Never had such a great experience with any contractor. So grateful to Eugene, Artem, Nick, and Alex not only for the great work they did, but for the care and attention they put in for 3 straight months. My house is built kind of complicatedly and the water heater isn't located in the most accessible place, but they were able to make it work. Not only that, but Eugene found me a new tankless water heater that would also work with my radiant floors - not only saving cost, but space as well. To say they went above and beyond is an understatement. They came back multiple times to make sure work was up to par - never half-assing anything. Really hoping I don't have any reason to need to reach out again soon, but if I do, I know who I'll be calling. Also, special shout out to Jeremy, Karen, and Kathy for their logistical help as well!"

"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.

Plumbing Heating Companies questions, answered by experts

Yes, copper pipes can freeze, crack, and burst in cold weather. In fact, of all piping types used for plumbing, copper pipes burst most easily when frozen. This is because copper conducts energy and loses heat more quickly than other types of plumbing. Copper also won't expand when the water inside freezes. Instead, it bursts or splits to accommodate expanding frozen water.

Yes. Sewer cameras are invaluable tools that can help pros safely diagnose problems with your septic system. Without a camera to look into your system, septic issue diagnoses would be a combination of guessing and past experience. However, a camera can help confirm ideas that your pro may already have about what’s wrong.

While you shouldn’t increase the flow of your low-flow toilet by adjusting the water level in the toilet bowl set by the manufacturer, you can make the flow as efficient as possible by ensuring the rim jets under the rim are unobstructed. To do this, use a mirror to look under the rim and scrub them with a toothbrush or a small wire to clear any debris stuck in the holes. You can also watch for leaks, make sure the internal components are in good shape, and replace them if necessary.

Usually it’s fine to leave a toilet clogged overnight, as long as it’s not close to overflowing. In some cases, the extra time may give the clog time to work itself out. For example, if it’s caused by an excess of toilet paper, letting it sit could result in the clog dissolving and you may be able to simply flush it away by the time you wake up. 

Only let it sit though if you have more than one toilet in the home.

The most practical and common setup is a toilet that connects with the sewer line or a septic tank. However, it is possible to install a toilet without a sewer line, and this can be particularly helpful in basements with no or outdated plumbing. An increasingly popular option is an environmentally friendly composting toilet. Other waterless options include incinerating or dry flush toilets, which pull the waste into an airtight container.
