Review on Sight Glass Spigot for Travel Berkey and Big Berkey Systems by Justin Olson

Purchased in March. In the beginning it worked great. No problem and we could see the water level so we knew when to fill the berks. It's June, about 90 days later. Started leaking a week or two ago. No matter how high the water level was in the Burke, the faucet from the spout will flow and continue to flow. I've checked to see if anything has been torn down or moved and I don't see any problems. I have no idea what happened, but I know it must have taken much longer. Thank goodness I kept the original bushing! Now Revain's return policy has expired and I have a $40 paperweight left over.
