Removing anti-siphon valve from a toilet tank
I am not a plumber or even in a plumbing-related field. But I do know how to change an anti-siphon valve.
The problem is two-fold. When I owned a condo n' replaced an anti-siphon valve 17yrs. ago
1. The bottom of the tank was completely smooth, no grooves in the tank.
2. Access to the back of the tank was not hampered by a 'floor-length' sink in close proximity.
Now, I have both these problems.
I had emptied the tank, when I noticed, unscrewing the plastic bolt is almost impossible. The back of the tank, where the anti-siphon valve comes through the bottom of the tank, is not flush, it is grooved. Meaning it is practically in-set. Making access even worse. Sure I could try to use a pair of pliers, but because of the tight position of the tank to the sink, I can't get the leverage I need to unscrew it. The homeowner(a relative) broke the valve off inside the tank, but the bolt is still on very tight. Their braking the valve off is no problem. The problem is still on the underside of the tank. I was going to try to drill a crack in the plastic, but have decided against that. Since it could damage the tank.
This toilet has been out of commission for several days. I need an idea of how to get the bolt off so, I can take off the parts to that valve off, then put the new valve inside the tank.
