Homemade Macerator Pump

In all honesty, this is not really a "homemade" macerator pump… it's just an assembly of existing parts.
Anywway, I have been looking for a pump for my TC and TT for some time and have seen mixed reviews about the Sanicon and Flojet units (plus they're fairly expensive). So I picked up a SeaFlo macerator pump on Ebay for $59 and bought a Camco clear sewer fitting for $9, and then made a PVC adaptor to fit them to one another. The whole assembly is simply press-fit together. I'm using a 3/4" commercial (garden type) hose from the pump to the sewer connection.
It's working great so far!

Hi,

I bought a maserator pump at West Marine. I was somewhat surprised at how much less a Marine maserator is than a RV one. I think it was less than $100. It came with a 1-1/2" inlet and outlet. I was able to convert to a 1" ID clear tubing, then used several sections of 3/4" PVC tubing to make it to the outhouse that I was parked near. I guess I was using 3 each 5' PVC sections and about 50' of clear tubing.

3/4" garden hose is much smaller, and about 1/2 the free open space of the 3/4" PVC. It took about 10 minutes to drain my 40 gallon black water tank.

Good luck with your project!

Fred.

Looks good! What could possibly go wrong?
