I installed a BRS float shutoff kit on my 50gpd Coralife RO. It ran fine for two weeks and today I notice a fine mist of water coming from both pre-filter canisters.
I shut off the water and found that both plastic filter enclosures had hairline cracks about 1" long. It was a vertical crack in one and a horizontal crack in the other.
My water pressure going into the RO is 60 psi and the first two pre-filters stay under pressure when the BRS cutoff activates.
Is 60 psi too much pressure for the plastic canisters on RO stages or was the plastic too thin in a spot. Seems odd that two canisters would crack at the same time?
Was there possibly a spike in the water pressure that fractures the canisters?
My main house line has a pressure regulator right above the main cutoff, so you would think that would protect everything downstream.
Before I put two new canisters at risk, I would like to know what caused this problem.
