to be tightened. When this happens, drain the boiler again and start over, or expect
to replace the gasket in a very short time.
As pressure builds up in the boiler the bolt and crab will loosen. It takes some time
•
for the gasket to reach its ultimate compression, so the operator should watch this
for several days and keep the bolt tight until it no longer loosens. This is especially
true if the boiler is operated intermittently; i.e., shut off at night to allow pressure to
drop. In this case, vacuum pressure in the boiler would suck the cover plate in and
allow the water to leak out of the boiler.
Re-using gaskets after they have been in service is not recommended!
