I have a 30+ year-old inground pool that had friction-secured weir doors installed when I moved in. One just failed. When looking at the underside of the skimmer cover, it has markings of "Swimquip U3" which seem to indicate a Pentair weir skimmer assembly. The Pentair weir door has a base plate with hinges for the door. Upon inspection, the remaining base plate for a previous weir door is indeed in place, secured by one or more screws.
My question: I ordered a replacement door (8650-4 door and hinge plate with correct dimensions and hopefully, the correct replacement) that is a Pentair with the correct dimensions. Can I detach the new door from its base plate and snap it into the existing base plate hinge posts, or am I going to have to get into the pool with a Phillips head screwdriver and replace the base plate as well? If the latter, this is a royal pain as this door only lasts a year or two.
