Alright, my RO system has been less than perfect to me over the past year and Im at the point where I may smash it if I cant get it where I want it. Im going to flood this with background details so that you may be able to help me out here.

MY system is a BRS 6 stage with the dual DI. I do have the filter monitor, pressure gauge and TDS meter as well. I have probably run 150 gallons through it at this point due to low water demands.

WATER SUPPLY

Currently my RO is hooked up with a t split under the sink, it is hooked up to cold water only. I am in an apartment building and my cold water comes in at city pressure which equates to about 30-35psi on a good day. The water is very cold and I feel this may be slowing the process. The hot water in the building is boosted after the boiler and boasts much higher pressures.

I have been trying to find a way to hook up both hot and cold under the sink and mixing the two. Would it be feasible to put a t split on the hot water and run both hot and cold into a Y fitting in the RO system? if this is feasible, should I put a valve on both hot and cold so that I can control the temperature going in? Does this make sense or am I crazy? Ive looked into mixing valves but they only appear to work at temperatures of 90+ which is way too high for the RO.

PRESSURE ISSUES

Lately I have been struggling to maintain even 10 psi. I have a good feeling this is due to clogged filters. I have changed the sediment filter without much luck in pressure, but I imagine after a year the carbon cartridges are about done too. I have ordered a full filter/DI kit as my di resin is just about exhausted as well. Hopefully this gets me back to my 25-30 PSI from before.




what do you guys think of my mixing idea? do you think it will work or am I head in the wrong direction?
