Nice Tank
Replacement for my old blue RO tank. I look at MANY tank before settling on this one. PAE Tanks have a dual bladder - one for air and one for water. Probably the most cost effective tank I have found. My RO flow was slow from basement to first floor faucet. I eliminated all 90 degree bends and changed to 100% 3/8 tubing- Inverting tank increased flow also. (tip from RO forum) I could not be happier with this tank and my water pressure/ flow rate.

A: • Shut off the main water valve.
• Dispense all of the water from the faucet.
• Remove the filters for stages 1-3 from their filter housings.
• Remove the membrane from its membrane housing.
• Do not remove the post carbon filter (Stage 5)
• Pour about 1 tablespoon of chlorine or hydrogen peroxide in the first stage housing.
• Put back together all of the filter and membrane housings. Make sure not to include the filters and membrane inside.
• Reattach all of the connections (as if your system was ready to be used again).
• Turn back on the main water valve.
• Let your system run.
• Once the tank is full, flush out the water through the faucet (at least twice; you may need to do it 2+ times if the smell of chlorine is not completely gone).
• Shut off the main water valve again.
• Install all the filters and membrane back into their correct housings.
• Reattach all of the connections.
• Turn on the main water valve.
