Description of ๐Ÿšฐ Certified GUEST Reverse Osmosis Filter: Enhanced Water Purification at Its Best!

the Super Speedfit acetal Single Check Valve ensures protection against reversal of flow. They are designed for conenction to either plastic or soft metal tube and they are intended for liquids only. Note that they are not suitable for air and vacuum applications. The inner valve is spring loaded and the fitting produces low headloss. It is also recommended that the non-return valve is regularly checked and maintained. Pipe connection has never been easier than with John Guest fittings.

Great as a backup backflow preventer for an espresso machine tank.

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.

Pros
  • Industry and Science
Cons
  • Uncertain

Protect your cabinets from water damage

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.

Pros
  • Check Valves
Cons
  • Crumpled

Great for adding a reservoir to a regular (non-RO) filter

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 osmosisโ€ฆ

Pros
  • Valves
Cons
  • Slightly torn
