I just joined. I have all sorts of problems, but just one for this forum.
I bought a house with an in-ground pool with an attached spa. Pool built in 1999, but I bought house in 2003. Pool builder is widely reputed to be a clown.
Near the spa we have a u-shaped PVC pipe structure with slits cut in it. For the first time, I start up the spa and water starts pouring profusely from the slits. What is this thing, and why would it start pouring out water after 11 years? I attached a picture.
