Question about Rinnai Webstone The isolator EXP tankless water heater Service Valves WRIK
I suffer occasional loss of heat in the sinks but the basement shower is the worst. Temperature will fluctuate from burning hot to icy cold withing seconds with touching the controls. This will last for months, and then not happen again for a while. First my serviceman thought our pipes might be clogged with sediment, but they are pretty new. Then he thought there wasn’t enough gas coming into the house, so now we have enough for an apartment building.
I think the dip tube in your water heater has failed, this is a plastic tube that goes in the cold side of your tank and forces incoming cold water to the bottom of the tank allowing hot water out at the top. When this tube deteiorates the incoming cold water mixes at the top of the tank causing the problem you have. the dip tube runs about 5 bucks but takes someone with pluming skills to install.
