Hi all I recently installed an new discharge water manifold on my Water Furnace (thanks to all who gave advice!). I installed a couple of Taco slow-closing solenoid valves and downstream of these a couple of circuit setters. Although the system is working well, it is quite noisy--particularly on Stage 1. Is there any way to fix this--or at least minimize it? One thing is that I did not install a pressure reducing valve on the inlet side of my furnace--I wonder if a lower water pressure entering the valves would quiet them down? Or, some kind of soundproofing? Thanks for any help. Cheers Matt
The very first step in tackling a noisy open loop is to install the pressure reduceing valve. They come in different sizes, so pay attention to pipe size on the valve, to coincide with your HP required flow rates in stage 2. Eric
