I just completed my first opening and everything went pretty well except for a couple things:
1. I have a Pentair FNS Plus DE filter that now has a very slowly dripping drain plug. Upon installing the drain plug i noticed that the outside of the plug itslef looked like it has been through a garbage disposal. Mainly because it looks like it has been really roughed up by the channel locks.
It became apparent why. It was very hard to screw in. I had to use a great deal of force with the channel locks to get it to go in and still it does slowly drip, maybe a drop every 30 seconds. Will this go away, or do i need a new plug?
2. I have a union at the return pipe that also drips at about the same rate. Very slow but still a drip, even though i torqued extremely hard on the union. I felt like i was going to break something.
How hard does a person have to turn on these plastic pieces? I am amazed that I still have the two dripping connections even though i have very tight fittings in my opinion.
