I installed a brand new Pentair 3 port valve and it is leaking from the top cover. One of the screws was left off from an earlier test fitting of the valve actuator when I installed it. I am using it in manual mode now and when I used my screw gun to put the screw back in I apparently over torqued it and now the screw does not get snug. The valve seeps water out from under the cover at a rate of about 1/10 gallon per minute.
Does anyone have any ideas on how best to attack this? Do to space constraints I have fittings too close to the valve to allow me to simply cut it out conveniently - it would be a major rework if I had to install a new one. I was thinking of whutting everything down and injecting some epoxy into the hole and then insert the screw before it sets up all the way and then torque it down after the epoxy cures. I was going to couple that with a bead of silicone sealant around the edge of the cover to help the seal.
Any advice is truly appreciated!
