For a month now I've only had warm water delivered at my faucets and showers and the pressure seems to be low. I've had 3 plumbers out to fix the problem. But it's not fixxed yet.
Before I called anyone the first thing I did was flush the HW heater. It is 7 years old, and my water is very hard. The water flowed fine and didn't visually appear to have much in it. But that didn't seem to help anything at all.
1st plumber said it was the pressure tank and replaced that. He also replaced the upper and lower elements in my hot water heater, both the upper and lower thermostats, AND changed the filter in the in line sediment filter.
The pressure seemed to be better at first but the water in the faucets is only warm at full hot settings...in ALL faucets in the house. When the pressure dropped a week later I called him again. He came back and said that when he replaced the pressure tank and repressurized it that probably I got a lot of gunk forced through the lines and that clogged the cartridges in the faucets. (I have a well, not central water supply). He tried to pull one of the cartridges(all are moen faucets, single control) but my water is so hard and the house is 30 years old and he couldn't get the cartridge unit free) He told me he'd have to cut holes in the drywall and replace all the faucets anc controls.
I didn't want a plumber ripping into my walls so I called for a 2nd opinion.
2nd plumber got a special tool to pull cartridges but again they were corroded in and wouldn't budge. So that guy cut a small piece of tile out, replaced the cartridge from behind, sodered the pipes back together, & covered the hole with an oversized crome plate . But that didn't solve the hot water problem. (Thank goodness we just replaced one to see if that would work) Now he is telling me I need a new hot water heater. However, when I open the faucet on the bottom of the HW tank I get scalding hot water, but the water kind of sprays instead of flowing which seems to indicate corrosion or sediment in the valve (there is not screen) But only moderately warm water is delivered at the household faucets (all). Doesn't make any sense to me. If there is hot water at the tank, why isn't it getting through the lines. My water is very hard and there is no softener. (yes I should probably get one) so I'm thinking something must be clogging somewhere.
Plumber 3 came out and assessed the situation and said the upper thermostat could be out, in which case since it was already replaced, I should probably replace the entire heater. But I showed him that the washing machine was getting scalding hot water (both thermostats are currently set on high). But when I demonstrated that I noticed the pressure in the washer was very low, and I'v also noticed presssure problems in the showers. He changed the in line sediment filter again and the pressure seemed to rebound. But the filters are supposed to be good for up to 3 months and it had only been 2 weeks since last change.
As a sideline I looked at the thermostats again and I noticed the upper was replaced with a single control thermostat, while I know the old one that came out had some sort of limiter that shut off one or the other (upper or lower ) once the water heated properly. I'm thinking this incorrect thermostat might have something to do with it. I asked the 1st plumber about that and he said that all the supply house carried were single control ones and that should make no difference anyway, that is why he went ahead and put it in.
In the meantime for a month now I've only had warm water, not hot, in my sinks and tub/showers, the water gets cooler after about 5 minutes and the pressure seems to still be lower than it was 6 months ago. I'm not convinced that the HW heater is the problem since the water is very hot at the tank lower faucet. Can anyone help me figure out what is going on?
