Re: Holding tank riser

The fix you referenced we did a year ago and have had no problem since. What I like with this solution is the continuous sanitary hose all the way from the toilet to the top of the holding tank, no joints to leak. Reaming out the deteriorated copper and fiberglass to allow for the insertion of the tube I found quite difficult until acquiring the proper tool. See the posting on 7/31/20 https://amelyachtowners.groups.io/g/main/message/53493?p=,,,20,0,0,0::Created,,aletes,20,2,40,75913168 for more details. One must also be meticulous about getting the resin completely around the pipe penetration from above so that it is fully sealed. We did abandon the old riser inside the holding tank as we could not figure out a way to remove it without cutting an access port into the tank.

Hi Tom and others on this forum,
Kaz and I are newby owners of our Super Maramu #171 and this is our first post to this amazing forum
I found a similar issue with our holding tanks this morning, it looks like there was a solid pipe through the bottom of the tank which then had a 35-40mm flexible pipe connected to it on the inside of the tank which went up to the top of the tanks and then curved over to point back down.
In both tanks the pipes have broken off on the inside of the tank, I'm thinking of replacing the pipe going through the bottom of the tank with a solid bronze pipe going up to near the top of the tank as in the modification suggested in this PDF
I like the idea of going into the side of the tank at the side as well, but do find going in the bottom neater.
I'd like to get the old flexible pipe out of the tanks as well, not sure if this is possible without cutting an inspection hole in the tank.
I'd be interested to hear about how you go about your modification.
Darren and Karen
