Dump Raritan CP in the shower drain each week and your problem will go away.

Could it be a refrigerator? My cockpit fridge catches me off guard occassionally. Also, if the A/C is on, it dumps into the shower drain box which could be causing the pump to cycle on.
The sump and the Tachs are the primary sources of pain.
Alex, there is absolutely nothing coming out of the boat, shower sump pump could be a possibility, but when the cycle up (or whatever) occurs, the shower normally has not been used for several hours or possibly at all, my neighbor in the next slip said he hears it cycle up when we are not even at the boat, do other 320 owners hear this, apparently Ray does, Im stumped, Mike
Ray Im with you, we may need to contact Searay and ask, if you find out let me know I will do the same, Mike
I have a question on rod holders. Did any of you drill holes for rod holders? and if so, where did you put them? I know there was talk in this thread about posting pics of where someone put them, but i never saw the photos. Any help would be awesome. Thanks
Mike
Thanks Alex - I do have the check valve - but am going to look it over more closely. I tend to agree this is part of the problem. You decribed my issue - there is another check valve further in line as well. On the weekend - I put my hose into the discharge hose and was able to get water to flush out at the thru hull - but the galley sink seemed to empty even better than the water hose and it's a pure gravity system flowing into the common manifold. . When the pump ran - I only get slow flow at the thru huil - dribbles /runs down the boat - no pressure. In fact - it did not keep up with the shower and I overflowed the sump box and the back-up kicked in. I have a complete new sump kit coming (warranty) - but I don't feel it will make a difference. Will be hooking up the hose again I seems something wants to block the flow. The other thing I noticed was that even the back-up sump pump seemed to struggle to get water out. I would have expected a quick work of the overflow. I will keep working this issue. RayThe way I understand that the primary issue with shower pumps going bad is the lack of check valve (at least in mine). Mine has a tube about 3/4' diameter that simply connects to the pump and discharges the water out. As soon as the pump stops the remaining water in the tube slowly goes back to reservior and kicks off the pump again. The cicle repeats quite fast. I didn't time it, but it felt like 3-5min. I was wandering if you guys have the check valve in your setup.
The strangest part is that the backup sump pump does have the check valve. So, I got the same part from MM and will add it to my main shower pump.
Alex.
