I have a 2002 Hunter 356. We are on the hook plenty in the Great Lakes. So we use our shower a lot. With our fail the shower box reservoir floods over every time. This happens with a very short duration shower. Such as shower on-get wet-shoer off-soap up-shower on-rinse off. I have replaced the float switch to no avail. The new switch seems to only ive the pump the on signal when it is at full high level. And the at times it won’t give the on signal until I tap on the reservoir box. of course by the time I do that the reservoir box is over flooded with soapy water heading for the bilge. I’m thinking of constructing a slightly bigger reservoir box and finding an upgraded float switch. The float switch brand (Atwood) is OEM on this Hunter and is the 3rd replacement. Any suggestions? Thank you…
