Trying to learn/fix my Santego

[bud37]

QR_BBPOST So y’all’s showers get pumped to the bottom of the boat instead of out the side? What a terrible design. The pump would always be facing head pressure.

I think the pic may be misleading a bit.....it looks like it pumps thru the boat bottom thru hull, we can't really see all the hose there at that angle.

i agree i was thinking that its discharging underwater by the way the pic is. especially if i orient my laptop the same way

Shower drain pumped into a thru-hull secock under the water line? This is only OK if there is a vacuum break on the outlet line (can't see one in the picture). There should also be a plastic or stainless "hair filter" to protect the pump from gumming up with hair and shower debris. Waste pumps are good at pumping lots of "stuff" - but hair is a special challenge and can clog the check valve or duckbills, allowing them leak back.

Old boats used to do something like this - with a cover over it or a closed tank and pump the shower drain and sewage/toilet waste overboard. Discharge of human waste has been outlawed for a long time now for inland and coastal waters. Gray water, like the shower, is another story. No federal rules prohibiting gray water discharge in the US, but Canada, some US states, and some lakes and marinas have rules about gray water discharge.

Most drains and pump outlets discharge above the water line. Unless there is a proper vacuum break, if the check valve/duckbill on the pump leaks back, the pump will cycle continuously or fail, filling up and overflowing the open-top box. Like a bilge pump, usually the most unreliable part is the float switch. My advice would be to replace this "box" with a proper shower sump (with a top) and run the outlet from the pump to the side of the hull above the water line, same as an A/C outlet or or bilge pump. This assumes gray water discharge is OK at your location. If you have a proper vacuum break, you are OK as-is, but still may want to change the outlet from the existing pump to be above the water line and close the seacock to prevent any chance of backflow. Put the new outlet on the side of the hull at least 1 foot above the water line.

Hope this helps - good luck!

I've never seen a discharge for this application going through the bottom of the hull in this vintage. I think the seacock might be the raw water inlet for the head or something else.

Viper, I’m with you. On my 3067, I had two seacocks
In that area, one for the head and the other for the a/c. Shower sump discharged mid-ship on the port side.

Yeah sorry for the misleading pic.The seacock is not for that sump but can't tell where that hose attached to the seacock is coming coming from

In that location, I'm thinking AC unit if applicable, a raw water head or washdown. Another possibility would be a generator if applicable but I wouldn't expect it to be that far forward.

Thats the drain pipe from your bathroom when you use the shower. Shower water runs into the plastic tub with the float switch.

Welcome aboard An Angels Faith! Glad to see another Santego owner!

Hey guys!! I need your help again to identified some of the switches on my dash/front panel of my 1989 Santego, thought I would find that in the owners manual but no

On this first Picture, what belongs in the two holes above the ignition keys?
