Pump that emptys the bath tub-gctid384061

[Guest]

Our 3818 has a pump that emptys out the bath tub. The pump motor operates but the pump is not evacuating water from the tub.

The bathtub evacuation pump is in the locker under the galley floor just aft of the stove. The pump is mounted on the tranverse crossmember at the forward part of that galley locker

Our pump motor is operational and the hoses from the tub to the pump is not blocked so I have concluded that the diaphragm of the pump must be shot.

Before I take this pump out of the boat and start looking for parts (a new diaphragm and requisite gaskets) can anyone tell me:

1. Who made this pump?
2. What model is this pump?
3. Where can I buy parts for this pump?
4. If parts are not available where do I go to buy a replacement unit?

I will try to post a photo of the pump and motor later today or early tomorrow AM

I had the same trouble on our 45. Trouble turned out to be a loose screw on the turning armature that wouldn't let the pump turn (IT GOT OUT OF LINE). Reset the arm and screwed it down and viola, IT WORKED.

In our 3818 I pulled the pump and replaced it with a shower sump with a built in pump. The Admiral didn't like the fact that everyone in a marina could tell when you were showering because th pump was so noisy. Now you have to really listen close to tell the sump pump is on. Basically it's a little bilge pump in a box.

Could be a hair ball ..........look closer at the sump filter the hair can clog it up pretty good

Shower pump got to where it would hardly pump any water at all. After inspection I found that the hole in the shaft coming from the bellows was worn into a long oval shaped hole. This caused the bellows to not move very much at all, thus very little water was being pumped out. Took the bellows unit off the pump to make working on it easier. Filled the hole with JB Weld and placed a washer just the right size over the hole. The JB Weld cured in 24 hr. and held the washer fast and tight. The washer hole was a little to small. So I drilled a new hole the right size for the shaft from the motor. Now the pump work's just fine.

Guys thanks for the ideas

Again the motor is working fine, the little shaft between the motor into the pump is is still going back and forth like crazy when I turn the pump on. There is NOT any blockages between the bottom of the tub and the input side of the pump. The offset that enables the shaft to push and pull against the pump seems to be a tight fit.

Can it be anything besides a torn diaphragm?

Who sells these things if anyone?

If it was a torn diaphragm it would probably spew water. Perhaps a bad or stuck valve. Manufacturer must be somewhere on the pump.

I had the same problem with ours. If you google the pump, there is a rebuild kit for it. I looked, but I can't find the receipt. I bought it from a Boatswain's Locker in So. Cal. He mailed it up for me, I took the pump apart and rebuilt the inside and it worked great. I want to say the rebuild kit was around $58.00 with shipping. Pretty easy repair. You just have to make sure you have it aligned 100% correctly when you reassemble.

When I purchased my 38 the pump did not pump water. I took it apart and found a lot of long hair bound up inside.

I have used it an additional 9 seasons with no issues.

Its worth a look.

Happy boating

Matched the pump by the illustrations and picture in the Catalog-turned out to be the right one-there was no reference by boat model at all.

Try this. Take the bellows off the motor and turn it around and look at the hole that the shaft from the motor fits into. If it is out of round at all it will not let the bellows pump properly. If the motor runs and turns its shaft then the problem has to be that the bellows is not moving up and down. These pumps have a very long life.

Any chance of larger pics of this? How did you access the bottom of the tub? I would like to do this, as I too have issues with the noise & clatter the current pump makes, not to mention it appears to have more rust than metal left on it.
