"As far as leaking I wanted to study the prospects of making replacement seals. The design is simple enough as there isn’t anything else to fail in the original valve"

Hi Phil,

As you, I have collected many of those 240 heater valves.

Over the years I have encountered 2 seal failures and about 4 with thermostat that would not work properly, like full open or closed.

I repaired a couple by combining the half that has good thermostat with the part that has good seal.

Before I was testing the seal at 10 psi and the thermostat by dipping the coil in boiling water and watch that little piston action. After it involve removing the C clip between the two sections, use a dremel to grind a little the riveted legs that hold the valve together.

For re-assembly I did delicate tack welds on the legs. There was not enough metal left on these to make secure riveting.

Having two 240 I keep a couple good heater valves on hand ready to install. But with time some thermostat and seals may go wrong even on the shelf so I am not trying to recover them all for now.

Have good day,

Roland
