Purewaterclub sent me new cap, and I Bought new metal adapter from home depot to replace the plastic threaded sink connector. 55/64" adapter was no good. Now works like a charm
I bought my 150gpd unit from pure water club and I have nothing but good things to say about them, anytime I have to buy anything i buy from their website and they sell on ebay as well. Best thing is that all they sell is RO units and their prices are amazing.....so +1 and thubs up for Purewater club....
I just upgraded mine with 400 GPD membrane since I have larger system now. I had to buy this from Ebay since they did not have single membrane that can do 400 gpd. But i buy my replacement cartridges from them as well very fair price and fair shipping prices...
