    Approx 2 weeks ago I rebulit an old Buckner valve (which Ewing now sells under their name). Replaced the diaphram and top end and it worked fine. Got a call today and the valve was stuck open. HO eventually turned off the water supply. I went out and turned the water back on and the valve had closed. I went ahead and pulled the top and checked for debris and flushed the valve. It was working fine when I left but am wondering if it's going to act up in the future. Don't really want to bill the customer till I know it's right. Ever worked any similiar cases or have any thoughts?

    Plastic valve? Flow control on the new bonnet?

    Plastic & no flow. I didn't mention it but the reason I rebuilt it was because it was not opening.

    Buckner used to catalog an imitation Richdel valve, but that was a while ago. A flow-control bonnet, appropriately throttled down, would be good insurance against a repeat stick-open.

    I have this happen with older valves (the HR100, etc.) from time to time. My rule is if it sticks open more than 1 time after a rebuild, I replace the valve. I'm sure it could be fixed but callbacks are lost opportunity and the customer just wants it to work. I bill the difference between the rebuild and the replacement if it needs to be replaced.

    I think on some of those 20+ year old valves that parts of the body wear over time and the new diaphragms just don't "fit" as well.

    Good idea. I'll replace the top with a flow if it keeps sticking

    bcg,
    This valve would be a tough replacement but I know what you mean. After a certain point that's what needs to be done.

    Flow controls rule, that's the only way to seat the diaphragm to the valve body.:clapping:

    A flow-control bonnet I think is going to be your best bet here while just replacing the valve would be your second best option. I would definitely suggest though, this you continue to have problems consider replacing the valve, or having someone come out and do it for you.

    IMO, you shouldn't be billing the customer for this, it should be covered by warranty.

    Jeez, things have changed for the better; factory warranty now covers parts and labor? :dizzy:
