Q: Please advise what model expansion tank I should buy for my 50 gal hot water heater in my home. My hot water heater is ONLY used for showers, washing machine, etc., it is NOT used for actually heating the home. Thanks.

The manufacturer would recommend an ST-5 part number 143N43.

Q: I have a W-M CGA 5 (140,000 BTU/hr); it currently has a Extrol 15 installed downstream of pump. I am told the expansion tank needs to be replaced. Should I go with the 15 or the 30? Does the downstream location present a problem? The current configuration has been in place for 7 years.

We would recommend a #30 expansion tank. A #15 would be too small. It is best to install the expansion tank on the supply side of the boiler before the circulator pump, at the "point of no pressure change."

Use a #30. Ideally it should be pumping away from expansion tank, but it probably won't be cost effective to change it, especially if it has been OK up until now.

This expansion tank is designed for use in closed heating systems (i.e. systems that continually cycle the same water). In an open system (such as any plumbing system), the tank would rust.

The #15 Extrol Expansion Tank is NOT intended for use in a supply system for potable water supplies.

The tank should be set to your system's psi.

Q: I have an old Amtrol 2 gal., model ST-5 that needs replacing. It will be installed in my main water supply line and is primarily to control pressure to my 40 gal., potable, hot water dedicated heater that will be about 18' from the expansion tank. 1) What model expansion tank should I use?. 2) When I install the tank vertically, does it matter which end is up and which is down?.

We recommend that you use the 140N43. You can install the tank with the unit pointing down.

This expansion tank is designed for heating systems. If you are using the water heater for a heating system, then this tank is fine. You can mount the tank both horizontally and vertically.
