I need to install a shower pump in a system with a 25 gallons cold tank and another 25 gallons hot tank. I was told that I need to upgrade the cold tank to 50 gallons. However, I saw this Triton T550i pump that seems to work with 25 gallons. The triton pump is a 1.2 bar - link bellow
Would that be ok? Has enyone out there installed any? Any other advice?
