Series ETX Non-Potable Water Expansion Tank

$ 34 00

Overview

This non-potable water expansion tank is designed for use in commercial and residential closed loop hydronic heating system piping to control the thermal expansion of hot water and maintain system pressure below the relief setting of the relief valve. This carbon steel tank is pre-charged at 12 PSI, tank volume is 4.5 gallons and features a durable expansion membrane that prevents contact of the water with the air in the tank. This rugged butyl diaphragm minimizes loss of the air change and ensures long and trouble-free life for the system. This tank is made of carbon steel with epoxy finish, mounts to supply piping, 1/2 in. MNPT system connection and a 0.302-32 in. charging valve connection (standard tire valve) to facilitate on-site charging of the tank to meet system requirements. The maximum working pressure is 75 PSI (5.3 BAR).

have a hot water radiator system in home. Plumber installed tank and Sweat Valve (supplies make up water to system as required) on the "hot" side of the burner. Should the tankd and sweat valve be on the cold/feed side of the burner? Does this make a difference? There is always water dripping out of the pressure relief line - bucket a day at least. =
Asked by: HotAndCold
Sounds like your relief valve is going and at the same time the expansion tank might be filled with water

First it is brand new and only time will tell how good it is by the length of time it lasts. Second and possibly more important it is actually the usual H.D. bait and switch, meaning that even though they are advertising you are getting a Watts product you are really getting a no name brand made in Taiwan. Another perfect example of a picture is worth a 1,000 words.
