STEVE: My hot-water tank has no good water pressure behind it.
TOM: Where are you spotting this? Is it at a particular faucet or fixture or is it multiple bathrooms throughout the house?
STEVE: Everywhere. My shower, my sinks, my washing machine, anywhere where I have hot – if I just have hot water going in my washing machine, it takes forever to fill up. When I go to take a shower, if I just have the cold – just straight cold water going, I have nice pressure behind it.
TOM: And let me ask you a question: how old is your house?
STEVE: Built in the 70s.
TOM: OK. I think you’ve got a problem with a valve somewhere on that hot-water line that’s restricting the flow. Because the water pressure is going to be the same for hot and cold when it comes into the house. So the fact that it’s going through the water heater and then slowing down means that something is clogging it or something is basically slowing down that flow. So I think that the problem would most likely be at the water heater itself: either the water flow into it or the water flow out of it. And it could be that one of those valves is stuck, closed or partially stuck.
I would close the valves all the way and then open them back up and see if that makes a difference. I would also follow the line back to make sure that every single valve is fully opened on that hot-water side. And I suspect that you’re going to find something that’s partially closed and that’s what causing this.
Steve, thanks so much for calling us at 888-MONEY-PIT.
