Hi all, I'm back for more. I had a poast below about installing an expansion tank. Well, I finally got around to installing the tank. In the process, I learned that my water pressure was ~100PSI. I measured it at a couple of different places, so I am certain it was accurate. This explans a copule of on gonig issues I have had including repeated failures of my water valve on my fridge! In any case, I quickly scampered out and bought a pressure reduction valve and installed it. Originally, I left it at the preset pressure of 50PSI. However, after completing the installation my shower was running lukewarm at best. Does not make for a peaceful DOJO! I thought maybe I had done something stupid and burned out one of my water heater elements. I checked them and all ohm out good. So, I decided to increase the water pressure to 75 PSI. After I have done that I still wasnt satisfied. So I took some measurements. Used a meat thermometer and caught the water in a cup to try and "normalize" measurements from show to tub. My water heaters (2 50 gal electric, in series) are set to 125. They are in the basement on the left hand side of the house. The materbath is on the first floor right above (almost) the heaters. The kitchen is on the first floor on the Right hand side. The powder room is first floor middle. Upstairs there are two bathrooms each with back to back vanities and a tub/shower combo. All of the tub/showers (including the master) have a single control valve that turns CCW for hot CW for cold. There is know on top of the tub spiggot that you pull up to divert the water to the shower. When the shower is running for all 3, there is no water comming out of the tub. The master measures 116 tub/104 shower. The upper Left measures 116 tub/106 shower. The upper right measures 104 tub/100 shower. THe hottest water is the Upper RH vanity (i.e., fartherest away from the Water Heaters) at 124. The coolest is the upper RH tub. So, my questions are, 1) why is my shower not as hot as before I put the pressure regulator in? 2) why is there a 10 deg difference between the tub & shower temp 3) How do I fix this. I tried to adjust the knob in the downstairs tub/shower, but it is already adjusted as far as it will go in the hot direction. I guess I could crank up the water heater temp, but really dont want to do that if I dont have to. What are my choices. Thanks,
