How to repair a leak under concrete in swimjet inlet pipes

Hi All,

I have a leak in my indoor pool. I let the water level naturally settle and the only thing below the water level seemed to be the swimjet inlets. It has four inlets at the pool, and putting a hose back through both the swimjet pump inlet I know they connected together. They go to two pumps that are above the pool level. The main drain is below the water level but I don't believe the main drain is connected to anything as the water level seemed to settle at a certain level.

I plan to use the "fix a leek" stuff to try and block the leak because the pipes run under concrete and a wall supporting the second story so I cant dig it up. However the instructions say to run the pool pumps and if its in the inlet pipes to try and run them reverse? e.g. put positive pressure in the pipe with the leak.
I cant think how to do this in my case, so I was going to block the inlets at the pool side and fill the pipe up from the pump side. I would not achieve any pressure but hopefully the leak will draw enough water through it to work?

Open to better ideas?

The pool is currently drained (apparently this was a bad idea, but its done..) and I plan to paint it with a gelcoat - see my thread in Building, Construction & Rebuilds

No pressure in the pipes means you won't be forcing the seal a leak out through the holes so it won't work. If you do use it in the system make sure you run Only In Recirculate or you'll end up with a solid filter.
Personally, I think you need a Pro with the correct kit.
