Submersible Course

[Andy]

Installed a Wally Sinker last summer in front of the house. Worked pretty good up and down. Pretty cool. This summer we are having an on going issue of the course lines filling with water including the bladders. We went through bladder by bladder line by line and purged the system, but now we seem to be back at square one. Any suggestions?

Also check the fittings, they can leak if not tight. Mine was leaking where I spliced the feed line 40' under...

When we purged it, we fixed fittings and leaks. Had the entire thing operating and holding air. Next day hooked up the air and no problem. A week later troubles return.

Put the pump on and follow your lines out from the dock on a calm day. The leak will show itself with bubbles at the surface.

There are purge fittings (vavles) at each end of the course. If air were pushed through each end at the same time while the shore lines were open, would it create enough vacuum to draw the water out of the bladders too?
