Since you have it appart replace the diaphrams and the rubber one in the dome. You have a hole somewhere. Make sure to clean out all old oil and fill with clean new..

Yes you have to apply pressure to the dome. Just takes an aircomprssor.. doesn't require a lot if air though..

I agree to replace the diaphragms. Water in oil is the usual cause of the milky look. Replace the diaphragms as they may have tiny cracks that are not really visible. You might as well have new diaphragms with fresh clean oil, and have a clean start for next year.
I never bothered to replace the top rubber in the dome.
Don't let pump freeze--costly to replace. Cover it with your electric blanket--or whatever you have.

I agree cover it up good in the cold.. I usually clean my pumps and run rv antifreeze in them..

I have one, you either have a pin hole in your diaphragm or it was frozen from the cold and pulled the diaphragm out of seat. Milky oil is water in the oil.

The pulsating dampner, the dome piece, should have 20% psi of your spraying pressure.
