We need to rework some plumbing on a pool, and the level of the pool is 3-4' above the plumbing. Obviously we need to drain the pool, but the problem with that is that the valves aren't working, and we can't shut off the skimmers, which are sucking in air. So far, attempts to blocks the skimmers have been unsuccessful.
Seeing as how we don't have an extra pump to bring in in order to drain the pool, the best plan that we've had so far is to just simply cut the plumbing (which we will have to attempt to stop from leaking) and put temporary pipes in that will connect the pump to the bottom of the pool.
I just figured I'd come here to see if anyone had any better ideas.
