Ok. I will use that gold seal stuff then over that use the pl roof flashing, hahah. I will be good to go
Nah, I just drilled a small screw into where the weir door tab thingy broke off. Works great. I actually broke the other plastic hinge tab thingy, on purpose this time, and drilled another small screw there also. It was VERY easy to put the weir door back into the skimmer without loosening any skimmer faceplate screws. It works great now!!
I am still going to seal the skimmer tho; I think I don't want to chance it "possibly" leaking, heh.
Yeah, also, I think the a weir door of some type is required for skimmers. I filled up my little "pond" to see how the skimmer would work without a weir door. The debris would go in the skimmer and then the same debris would sometimes come right on out, heh. I then put the weir door in and the debris never escaped. The air pocket in the weir door allows the weir door to float just enough to create a very small 1~3 centimeter tall waterfall creating a little vortex thing. This vortex thingy is what prevents the debris from escaping my skimmer.
I can definitely relate with the lack of pond supply stores. I live in an area where my neighbor is 5 miles away and the biggest city nearest me, Amarillo, is 80 miles away and just ~190k population and not many pond outlets !!! grrr. Getting pond plants are a hassle since I have to buy 12 of a kind if I want to buy through the greenhouses. The greenhouses here only have a very small stocktank where they sell pond plants from and they only order them once a month even if they sell out much sooner, such a pain.
