First post- this site seems to have more than it's fair share of rodi expertise- I need some of that.
Have a newer Aquamaxx Puratek Deluxe RODI unit that up until now has performed very well.
Added a second membrane to it. I have it connected via faucet as I am uncomfortable hard plumbing this in with the pushlock fittings, a mistake was made and HOT water was passed through ot for about 20 minutes. The particulate casing deformed and blew off with granular filter pieces found in various locations inside the unit. The unit operated at 90psi with the single and dual membrane, it is now operating at 70psi which may be sufficient but just wondering what I am missing. Booster pump was pulled apart and looked ok cleaned a bit of filter debris- pump on 70psi, pump disconnected 602psi, on/off solenoid was replaced- had some debris in it- I think the old one is still serviceable, flush solenoid was pulled apart- looks good and bypassed- no difference in psi, all filters and membranes replaced- with close but not exact replacements, plastic filter casing replaced, pump deadheaded and showed 150psi, new gauge installed- similar reading. The booster pump is not adjustable- I have not looked at it in detail- I suspect the pump is slightly compromised- what else is there- fairly simple when digging but I have little experiance. The 400 waste water orifice seems to be simple enough. Without checking I believe the original membrane was 100gpd, the replacements may be 90gpd.
