Wash / Livewell pump - unwanted water flow

[abl1111]

PS -

Washdown pumps and Livewell pumps - you have to decide if you want to have (1) pump do both things. If so, I did a lot of asking a few years back and I was pointed in the direction of the Jabsco products over Shurflo. I have a Par Max (4) now and in other boats. I've have no problems and plenty of water pressure...
