Air admittance valve/sluggish flush

[Bob Eager]

Of course. My mistake.

..and then stick an apple in it.

Thanks both, but I've a subsidiary question! The septic tank does have a vent on it - fortunately it's not at all unsociable! The point about mechanical failure is a good one, but it gets VERY windy where I live, and I'd be concerned at anything poking above the eaves being blown off. I guess I have 8 foot vertically from toilet bowl water level to the top of the vent so lopping the top off the pipe would possibly eliminate the low pressure and be an alternative. What problems might that introduce (eg too close to the windows round the corner of the house) and how much height do I need to retain though?

As long as the valve is above the highest window no prob. If the window is around the corner, then none at all.

He means Morons, Eliza. always terminate a stack vent directly under the anal orifice of a moron. Saves buying the toilet.

(note to others reading this. Its astounding not that IMM can't spell, but that he doesn't recognise when he can't either).
