Hey Brats,

I have a broken filter drain plug on my port side fish box. It causes more debris to enter my macerator pumps and jams up my pump. I would like to find a replacement plug or find a better alternative?

I will change to whale gulpers once my current jabsco pumps go out, but untill then I do need a solution for my broken filter plug.

I appreciate any tips or help on this.

I placed a 2" square piece of plastic window screen under the cap in each fish locker to keep anything larger than a grain of sand from going into the pump.

On the bottom of the Jabsco pumps is a rubber cap. Remove the cap and you can turn the pump manually with a flathead screwdriver to free it if the pump gets jammed.
 
I found a bathtub strainer that fits well. I'm interested in the whale gulper pump mk3. However, It says there is no motor to burn out and no explanation
of how it works. Can some one tell me how it pumps with out a motor since I burn out Jabsco motors almost every year.

Gene,
If it does not have a motor (my internet is painfully slow, due to Hurricane Sally), it could be a solenoid operated diaphragm. (Like automotive fuel pumps). I have used Whale gulper pumps for some years. There are manual--"Arm strong" type motors, and rotary rotary electric motors in the ones I have used. It may have a smaller motor and geared mechanism to give the low amperage draw.

It does not have an impeller to wear out, bend, disintegrate or clog.
 
I looked at the brochure for the Whale Pulper pump mk3. I'm a little confused, as usual. Nowhere does the brochure advertise that there's no motor. Indeed, looking as the spares sheet, there is a gear set, which I suppose runs the diaphragm. If I see gears, I assume a motor. One ad says there is no impeller motor, which is reasonable since there is no impeller. But instead there is a diaphragm which needs to be driven.

Were does it say there's no motor? I'm fascinated, because I've burned out several macerator pumps.

I switched my macerator pumps over to the Whale Gulper Grouper pumps several years ago and have never looked back. They pump a bit slower than the Jabsco macerator pumps but they have lasted WAY longer. As I indicated in some text messages between Joe and I earlier in the year, when I had the Jabsco macerator pumps, I was replacing them almost every year. I replaced one of my macerator pumps in Nov. of 2013 and the other in late July/early August of 2014 with the Whale pumps and the same pumps are functioning well today.

In May or June of this year, I had one pump with issues and I wound up taking it apart to clear out a piece of plastic that was clogging it. That gave me a chance to figure out how it works. In brief, the main body of the pump has a motor driven piston that pulls and pushes on a diaphragm at the bottom of the pump. There is a rotary motor attached to a wheel that pushes and pulls on a lever to drive the piston-like rod that pushes/pulls on the diaphragm. Transverse to the bottom of the pump is a chamber with the water inlet and outlet on either end of it. When the diaphragm is pulled up, water is sucked into the chamber, when the diaphragm is pushed down, water is forced out of the chamber. At the inlet and outlet are silicone check valves that function similarly to heart valves. They allow water to only flow in at the inlet and only flow out at the outlet. It's a very simple, very reliable design.
