Hi chaps I've a 300gpd ro with boast pump - pump lasted me two years and died on me - I've recently bought a larger on for 600gpd and out put water is twice as quick which is great thou TDS has creeped to 0.18 from 0.10 but I'll take that for double speed filling. Only run one full fill with it but the pump is roasting hot - don't remember my last one doing that. Is this common with 600gpd pumps or will it blow on me. Cheers
