I haven't posted many updates. We do have water, but its been a long time getting solutions to issues. Recently my PB has returned to fix our outstanding issues and have discovered that the jets in our spa are possibly plumbed wrong. Air and water comes out of one jet, when that jet is covered air and water comes out of the next jet. Waiting on confirmation from them if that is the issue. The fix is to access the plumbing from the inside to fix it.
My question is, assuming that they have to fix the plumbing from the inside of the spa, what should I request be done to the interior of spa to make sure the finally job is leak free and done right.
