patfan64 Posted July 23, 2010 Report Share Posted July 23, 2010 I am trying to open my pool (I know I'm late) and it was closed by a pro last year. I found three pipe openings at the bottom of my spa (integrated with the pool.) One was not closed (I imagine that is the link to the main drain) and two were. One had a threaded cap and the other a rubber cork looking thing. I've got one pump that runs both pool and spa. It is a gunite pool and probably 20 years old, if that helps. Do I need to remove both the threaded and cork? I hope I've given enough info. Thanks Quote Link to comment Share on other sites More sharing options...
Pool Clown Posted July 23, 2010 Report Share Posted July 23, 2010 Can you call the pro and ask how he closed? Threaded plug could be a hydro-static relief and should keep capped, but that isn't common in a spa. You could take it out and see if you start loosing water, then you could cap it back up. Just curious, is the line with just a cork in it, have threads like the other? Quote Link to comment Share on other sites More sharing options...

Thanks I thought maybe the pro ran out of threaded plugs, and had to use a cork. Quote Link to comment Share on other sites More sharing options...

simple Posted August 3, 2010 Report Share Posted August 3, 2010 The threaded cork thing is probably an expansion plug Quote Link to comment Share on other sites More sharing options...
