I'm looking for a new system as mine is getting towards the end of its days financially.Currently running a HOH RO 51 but new parts are going to cost a fair bit.I'm wanting to go power free so have looked at the water pentair PRF system but is designed for 40-80 psi.I have 90 psi.Any suggestions on an easy setup system or should i just get a pressure reducer and get a pentair?Cheers
