Welcome, my name is XXXXX XXXXX I will do my best to help you with your issue.
How are you bleeding the pump? are you bleeding with the burner running?
i am using the bleeder on the forward facing bottom side of the pump. yes it is running while attempting
you're bleeding from the bleeder indicated in the picture above?
yes that is the bleeder i am using
Ok, then the most likely culprit (assuming the pump is functioning properly) is a clogged pump screen
ok. where is that located?
What is the brand and model of your burner?
the label says weil mclain qb180 on the burner
the pump has suntld a2va-7116 on the pump
That's an old burner. There are 2 hex screws on the face (left side of burner) of the pump. You'll need a new gasket and probably a new screen. You won't find any plumbing supply houses open today so you won't be able to get parts until tomorrow
I'd remove the cover and bring the screen and the cover with you to the supply house to get the right parts
Of course there's always a possibility that the pump has failed
the hex screws can be seen in the pic you sent by the bleeder and opposing side?
the pump sounds like it is spinning ok and no abnormal noises from it
yes left side
Your description doesn't rule out a bad pump
we would check and replace the screen first
ok. i had that off earlier and didnt see a screen, just the shaft and needle bearings in there
There should be a screen. If not you probably need a new pump.
The screen is cylindrical
ok thank you i will try it
