Re: Head discharge hose clogged with calcification
Hi Bill,toggle quoted messageShow quoted text
I had the same problem. I went to Home Depot and rented a small hand held drain snake, not the variety on the drum, but instead the type that is fairly short and attatched to a crank handle. With this device I was able to "break through" the blockage. I would recommend putting some masking tape over the wooden cutout frames to avoid scratching them.
I would also recommend sending a similar slightly longer device up the discharge side from the outside of the boat.
After I cleared as much of the blockage as I could I shut off the seacock and filled the holding tank with a mxture of fresh water and septic tank cleaning solution. I let it soak for a day or so and then opened up the seacock while at the same time flooding the holding tank with fresh water via the pump out opening.
Hope this helps.
