BUFFER TANK

[stratton]

Looking for advice -
I am adding an 80 gallon buffer tank. Pipe from boiler to buffe will be 1.25 inches. Ports on buffer tank are only three quarter inch. Will there be a restriction problem? the tank is a hot water heater so there is no coil inside. Do you guys think this will work or do I need a tank with 1.25 inch. I really do not want to return this tank if I dont have to.

What type of flow rates?

Look inside most 1-1/4" zone valves or control valves for balancing, etc. You will generally see an orfice inside with about a 5/8- 3/4" hole Same with some of the low cost, reduced port ball valves.

Increase as soon as possible, close nipple and a 1-1/4 x 3/4" reducing coupling. Limit the flow rate to around 12 gpm and you will be fine, it may cost a bit of pressure drop, but with only two connections or so not to worry.
