Hi everyone! I'm new to this forum. I'm a basic DIYer, by no means a professional. I ran new 3/4 copper pipe to install a whole house water filter. I installed shut off valves and pressure gauges before and after the filter system, as well as a straight bypass with a shut off valve. I've noticed that when my hot water heater runs, the pressure increases on the outlet side of the filter (80-100 psi), but remains consistent at the incoming side (60 psi). When the pressure is increasing, if I open the bypass valve up top, the pressure drops to the same as the incoming side (60 psi). I've also noticed the relief pipe on my hot water heater has started dripping. It has never dripped before. Any thoughts would be greatly appreciated!
