Just moved into this home a couple months ago - 13x26 fiberglass with fiberglass spa overflow- pointless to even have the spa...anyway I have put a caulk line under it already and have turned up the return to spa and the best spill over return I can get is still running back along bricks and under spa moving my concrete and pavers. I have placed a rubber fish drying mat under the spill over which finally has made the water stop from going on bricks and ruining patio. Now what am I going to do?
