🚰 Certified GUEST Reverse Osmosis Filter: Enhanced Water Purification at Its Best! Review

Ideal. John Guest hardware is the bomb. Anyone say more about this? They are good, sit well, do not flow. Use this as double insurance for a backflow preventer with a float valve in the espresso machine tank. I bought a different brand of faucet and it leaked. Several guest fittings I've used have worked with no issues. I recommend them.

My reverse osmosis faucet ran into the under sink cabinet twice leaving stains on the sides of the cabinet. You don't know it's leaking until it's too late. Sometimes it's a drain line from a reverse osmosis faucet, and sometimes it's a small drain pan in a garbage faucet. The reverse osmosis air gap design is terrible. If you want to protect your cabinets from water damage, then I think this is the right solution. No more gurgling noise, no more water overflow from reverse osmosis faucet.

I bought this to add a pressure reservoir to a regular (non-RO) filter. We have had a reverse osmosis filtration system for many years. It worked well, but changing the filters was a bit expensive, so we switched to a simpler two-filter system. The taste of the water is just as good but the problem was that the flow rate was very slow. Because we use a filter to power the ice machine, the ice cream became smaller and rarer. So I thought I could add a pressure vessel from a reverse osmosis…
