"We noticed black particles/materials on top of our water heater. Our thinking was that the particles were coming out of the top of the water heater, where there is an opening that was just below the venting pipe that leads to the roof. I called Better Water Heaters and Frans (owner?) answered. I did not realize that he was in his truck on the way to another job. I described what we saw and did not think it was coming from the water heater. He suggested that I sent him the pictures that we taken and forwarded to him. Shortly thereafter, he called back and reconfirmed to me that he did not think the particles/black materials were coming from the water heater and that it is more likely, coming from the roof by way of the vent pipe. Frans responded fairly quickly and did not charge me for his professional assessment of the problem. As a result, I will call Better Heater Services in the future whenever servicing is required."

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"The plumber showed up on time to replace the hot water heater and completed the job in just a few hours and then also give me some advice on a running toilet that I had. He filed the papers for the inspector and the inspection went fine a few weeks later. The price quoted before the job was the price I paid afterwards. I had gotten lower quotes but there was always a caveat on the price offered. Valley Plumbing was straight forward and honest. I would use them again.
