Bilge pump
It is possible to install an automatic bilge pump in an H22. Others that frequent this board have done it and so have I. There's really only one spot for it and it's under the deck plate at the foot of the companionway ladder. Only the smallest rule pumps will fit. As far as the pump discharge goes, I suppose you could use a check valve along with the deck discharge thru-hull. Personally I routed mine from the pump to under and into the starboard quarter berth access and out the back of that to a seperate thru-hull. Which ever way you go with the discharge you'll need to make all your electrical and plumbing connections prior to putting into the bilge. And for mounting the pump and switch, I simply used 3M 5200 adhesive caulk to secure it all into the bilge.
