New Challenge - Shower drain

[beyond]

So I've got a bit of a challenge. My shower is behind the single axle, and is almost directly above the black tank. Due to lack of real estate, the grey tank is in front of the axle.

I am thinking that I will need to attach a pump below the shower drain to get it to the grey tank. Anybody done this or have any thoughts on how to best do it?

Thanks!

ya could raise the base height in order to increase the "fall"
in the drain line - water wants to go downhill. i would avoid
pumps if at all possible - gravity is best

I still don't think I have enough drop though. As it is I am 6 feet tall and can't go up much without losing too much head space.

Ideally you solve the problem w/out a pump . . . however there are systems designed for this situation, look at Marine Parts Stores/Websites. If you go this route, make sure you design it so you can service the pump/drain as it will most likely need it at some point.

(it seems like you could move your grey right next to your black tank and drain directly into it . . .)

If you lower your tank a couple of inches,you should have plenty of fall,you even have a closet between them to run your vent thru the roof. Dave

That kind of setup is not uncommon. I believe that Scamp makes a couple trailers that are set up like that from the factory. Maybe it's another maker. Anyway, not unusual.

Take a look at products like the Jabsco Filterless Bilger

Jabsco Filterless Bilger Sink Shower Drain Pump - 50880-1000 - BoatersWorld.com

It is self priming and can be run dry without damage so you can set it up in a cupboard where you can get at it, with no sump, and it doesn't require a filter.

It's going to be loud and it is one more thing to break but if the geometry won't work out any other way you're stuck.

The showers in my sailboat drain into a sump and are pumped out with a Jabsco diaphragm pump. The pump is not really a problem but you really do need a screen type strainer on the suction side and they plug up frequently with hair. On a sailboat you really don't have a choice.

Your potable water tank, as shown in your drawing, is in the wrong end of the trailer. It should be forward of the axle or up front.

I have never seen a proposed potable water tank in the rear. It will adversely affect handling and also cause the trailer to have improper tongue weight.

i used a pump - a whale gulper - as we put the grey tank above the floor. yep, its loud. but it does the job. no filter, can run dry... want to hard to install.
