when to replace oil furnace shutoff solenoid

[paulmars]

Pressure held for 24 hours, then I removed gauge.

Suntec a2va-7116 says pressure will drop then hold when burner is shut off. "Cut off pressure could be less then 80%. The important operation is that it drops to some level and stops." "If pressure drops to zero the unit should be replaced."

So mine dropped from 100 to 63, then slowly continued to drop and was at 45 after 24 hours.

I asked Beckett and they said it should hold for 10 minutes.

Then they said that I should replace my pump. Ive asked twice and they wont explain why I should replace it.

Thoughts?

Thanks,
Paul

100 to 63 in what amount of time?
What is the issue again?

Issue is me wanting to know why this pump is bad, if the test says good

If it is working ok then yeah, ignore them...if its not, then maybe experience says thats a bad pump?
