Does anyone have any experience with thermal expansion tanks? My water pressure increases noticeably after the hot water has been running. I don't know how much it increases -- it's not enough to trip the pressure release valve. But I find the increase in pressure annoying and I worry about the wear on pipes and fixures. How well do they work? Do they keep the pressure pretty constant? I think my pressure regulator is set around 60 PSI. I have seen a Rheem model sold at Home Depot and other places. Are some models better than others? Is there any maintenance required on them? Thanks for any information you could offer. |
