Hi all,
Pics: Main drain for the CH system - at the lowest point of the system.
It is 25 years old - and I cannot easily replace it.
It is leaking.
Q: How does this particular drain plug/fitting create its seal (when tightened).
It is directly exposed to the elements all year round.
Is there likely to be some sort of rubber washer or diaphragm inside?
If its simply a washer - whats the right type of washer to choose (given it's purpose and exposure to extreme cold during winters)?
It's leaking and I'm losing pressure in the CH system - simply tightening is not sorting the problem.
Leonardo.
