Tim Allen and the shower sump

My neighbor has been having issues with his shower sump. He has been through two different shower sumps. The floats always work, just never seems to pump out the water. The sumps use a Rule 800 and the pump always seems to get clogged or cavitate. I told him to he needed more power.

He invited me over today to look at his new shower sump. I am impressed with how well it works. He upgraded to a Rule 2000.

I installed one of these about a month ago
Very happy with it. I love the new screen design.

I am a Whale pump fan too. This is the second boat where I have replaced the poorly designed system using a centrifugal pump as shower drain with a Gulper. In the current boat, the shower sump doubles as the air conditioner drip pan sump. I left the float switch in the Attwood sump box, removed the plastic screen which was always getting clogged, and placed a Gulper atop the sump with a short length of hose reaching down to the bottom of the sump. Works a treat. In the older boat where the sump was just for one of the showers, I ripped out the whole sump and installed the Gulper in the drain line with a pull switch in the shower to operate it as needed.

Thinking of shower sump pumps reminds me of the time in 1989 off the coast of California when I used one to drain three feet of water out of a Chris Craft Roamer.....

I made a new shower sump and put in a Whale Gulper IC pump. Works great.

Another way to go is to have a grey water holding tank for the showers and sinks in the head. Use same components as for black water. Hair, dead skin, soap scum and the like seem to have less impact. Can even throw in enzyme or surfactant periodically if necessary.

I think the sump should have some holes bored in it so it will eventually drain the "dregs" into the bilge. The holes can be pretty small and near the bottom. They will keep water in the sump from becoming soap solid or scummy.

I'd much rather have to clean it out than let it make the bilge gross. But I'm also a fan of the no-sump setup unless too many things need to feed to it (where no sump becomes impractical).

My sump is more like a holding tank -- 40 - 50 gallons, and as you suggest all the showers and sinks (other than galley sink, cockpit sink and crew shower) drain into it. But, it has a float switch to control the whaler pump, so in practice little water is ever in the grey water tank unless we shut the pump off when, for example, we are anchored in a nice cove and don't want a stream of shower soap suds trailing from our boat.

Nick where does your Gulper draw the water from? I was thinking of letting the fwd shower drain into the small sump in the bilge keel. I have a Gulper that keeps that pretty much empty. Main bilge pump is only needed or emergency.

The Gulper has to be connected (by hose) directly to the drain fitting in the shower base.

Your idea to drain the shower into the small bilge sump is a possibility. However, there will always be a small amount of shower liquid left in this sump. Also, the sump will probably overflow a bit during showering, temporarily wetting a larger area of the bilge with soapy water.

Regards,
Nick

So how does that work? In shower, pump senses water and turns on, pumping overboard? No water pump shuts off.

I love that my shower/ sinks gravity drain overboard. Ever get clogged 120psi of air pressure cleans them right out. Do have to clean the boat next to me when that happens though lol.

Is the whaler gulper 220 the unit that is being used for shower sumps. Do you use it without a float switch and let it run wet/dry during the shower? Whale claims dry run capability. Eliminating a float switch would make for a simple Installation of the gulper pump.

Thanks Nick. Regardless the Gulper is the way to go for any lower volume applications. No problem running it dry.
