Brand-new model 400 filler and it admits water at the top in a trickle. Water being the precious commodity it is, I have to stop the trickle.
1. The black seal therein (242) appears in perfect shape, no dings or nicks
2. Same for the white (nylon?) below, no nicks or cuts
3. Water is rainwater, filtered and perfectly clean
So it appears to me that the water is coming-up the center of the seal, which I assume is supposed to be sealed itself by the stainless steel wire that connects to the lever arm and float. I applied a dab of "lube-tube with silicone and PTFE" to the hole in the center of the seal that the stainless wire protrudes through, but it still leaks.
I can take the whole shebang back to Home Depot for a new one, but guess I will buy a new seal or two first cuz that's easier.
But it puzzles me how this stainless shaft, which of course protrudes thru the entire 242 seal, is supposed to achieve a perfect seal and stop the waterflow? Is water pressure against the underside of this seal supposed to cause it to distend in such a way as to make a watertight seal around the metal shaft?
I'm not understanding this thing--someone help please!
P.S. I have looked more closely at both the stainless pin and the 242 seal (with a magnifying glass) and can see that there is magic at work. The "pin" has both serrations and a "waist" to it, and the seal has extremely tiny holes on either side of the protrusion that enters the top of the valve. It probably was not wise to apply any lubricant to it, and I'll certainly clean-up the pin before putting-in a new seal. Still, I hope someone w/a better understanding of how this thing intends to work will post here. I can bearly spel "fluid dynamics"!
