Hi Jeff..I like the look of those type plugs ..but as Im a stingy old git..Im not spending £18 on them to sort one leak. If I had a few leaks..I would then consider it.
I have plenty PVC patch material..from a repair kit and also a re cycled Seago.. so Im still going down that route..but keeping both Fenlander and your advice in mind for an internal patch before the external patch and final finish.
Its still raining here so I cant do the actual leak yet.. but have now worked out my technique for applying the internal patch.
I will use a ¼” drill bit to enlarge the actual PVC leak hole ..and here I have used a piece of ply to simulate the PVC tube
First step is to cut three patch disks .. two are around ½” diameter and the third around 1” diameter. I drilled two small holes in one of the smaller pieces and also the larger piece. I also require some fishing gut..at 25lb breaking strain..its strong enough for the job. The holes I drilled are a nice fit for the fishing gut to pass through.
Second step is thread the gut through the holes in the small disk.. then PVC glue the other small disk to the rear of the disk with the gut. Leave overnight to cure. This seals the holes around the gut
Step three is thread the larger disk onto the fishing gut but don’t slide it all the way to the smaller disks. Fold the smaller disk and shove them through the hole in the tube. When I do it for real..they will be slobbered in a mix of PVC glue and Sikaflex marine adhesive to form a sticky paste.
Step Four ..once the two smaller disks are inside the tube ..slide the larger disk up the gut..roll it up and shove it through the hole. Again..it will be slobbered in sticky goo when I do for real.
This photo shows the “rear or inside” of the tube. The disks are dangling on the fishing gut. (you have to use your imagination to see all that slobbered sticky stuff that they will be covered in.)
Then its simply a case of pulling the fishing gut from the outside of the tube..and all disks are pulled into place. Secure the gut to keep tension on the patches until the slobbery stuff has cured.
Once cured..the fishing gut can be snipped off..then the external patch applied.
Anyone have any better ideas or see any pitfalls to this way ?
I would prefer to do the repair with materials I have at hand so not wanting to order stuff that I wont use. I also don’t want to cut a large hole in a better access location so I can access the internal area of the leak.
