Be sure all connections are tight after you disconnect your hose. If they are left loose, they often leak. We are charged for every drop of water we use. If you notice any leaks or problems with the any tank, hose, tee, or connection, PLEASE see if you can remedy the situation by tightening connections or flipping the switch on the tee which will turn off the water to the tank or the hose. Contact the office with any water concerns so they can be addressed promptly. Thank you! We appreciate your help.
