update surge tank installed..remember freeze out plugs

Wiz,

I was in a position of repairing things without parts for many years. No outside patch will hold on the PE tank at those pressures and temperatures. What will work is the smallest sheet metal screw you can find and just drive it into the hole. any thing larger that the smallest will have more force on it. The compression of the plastic around the screw is on your side. No sealant should be required.

Good Luck

Matt
