I installed a DEl UVC-50 this year and ended up with very high pressure. Looks like the Del has a lot of 90 degree bends and I made the mistake of installing in with a 2" to 1.5" reducer fitting. Next year I will make sure all pipes coming out of the pump are 2" right through to the filter and into my heater. Unfortunately the heater only accepts a 1.5" connection in and out. I have check valves installed both on the intake and pressure side of the system. I plan on installing another Del UVC-50 and split the flow out of the filter between the two UV sanitizers. Hopefully I will be able to reduce the head pressure and gain more efficiency out of my pump. Any thoughts or suggestions about how I can optimize flow rate through my system? I have a spare Pro-Grid-7200 and considering running both filters (Perlite media) in parallel to gain more efficiency out of my pump. I'm an Engineer and like to play! Lol! Comments are welcome.
