Jackhammering water pump

I know it's too late, but don't waste your money on the ShurFlo kit. Find a local Ace Hardware store, browse through the plumbing section, and find a pair of washing machine hoses in a bag on the bottom shelf. (The ones I got were white and 36" long, and IIRC less than $15) Then head to the fittings and get a couple of schedule-80 threaded close nipples. Take the hose off the outlet of the pump and rotate the fitting 90 degrees, then connect the nipple and a hose to the existing plumbing, then loop the rubber hose about two or three times in a loose loop, and connect it to the pump outlet.

This was the setup I used on our popup...

I did a similar setup on our current travel trailer, though I can't seem to find the pictures at the moment...
