Chuck, just a couple of quick things on this AM's post on bumping:

1 Please remember to open the air relief valve for a few seconds (then close it again) to relieve some of the pressure on the tube sheets so they don't crack from being 'Bumped'. Cracked tube sheets will allow DE to bypass the fingers and end up in the pool.

2 There should be a backflow prevention 'flapper valve' where the water from the pump enters the filter. They fall off a lot and as long as you have the Jandy valve closed it's no problem, unless the pump is higher than the pool in which case, you may find DE on the pool floor near the MD or in the skimmer, before the pump turns on for the day. It's a minor thing, but the DE shouldn't be able to get into the pump from the filter. It's probably not a problem for you, but might be for others (some systems get plumbed without a valve )

I wish the both of you well and hope you get to enjoy your pools a smuch as posible
