so when you flush a toilet or discharge water into a pipe your telling me that it is not positive pressure
I didn't say any such thing, but as you seem not to understand I'll explain.donametchi said:so when you flush a toilet or discharge water into a pipe your telling me that it is not positive pressure
Er, I'm very much not requesting or requiring your help.donametchi said:if you are refusing to understand how an aav operates then i can,t help you.
Rest assured - you might insult me but I won't feel insulted by someone who doesn't know what they're talking about.sorry if you,ve felt i,ve insulted you
To admit air of course, in those scenarios where this is the right thing to be doing. What they can't do is vent air at positive pressure, hence they shouldn't be used where a vent is required. FFS, how many times do I have to point this out?but why have an aav then.
Please supply a reference to any document that backs up what you're saying.when they are mean,t to be installed in situations when you can not vent to directly outside.
FYI your spelling, grammar, and punctuation, all continue to suck.hope the spelling suits.xxforgot to hit the spell check.
I suspect sparrows are likely to be more of a problem than carp.Garfeild said:...fit basket on the top to avoid c**p falling in and blocking it.

So it could be carp in the soil stack after all.emsee said:As far as I can see (I haven't been able to get right next to it yet), the pipe is just an open end - there doesn't appear to be anything on the end of it.
No.If there was a valve, could this be fitted lower down in the pipe somewhere...
Yes....or is this type of valve always on the end of the pipe?
I'd be interested to know where that rule is documented.holty said:durgos are allowed for at least four properties on the same sewer run, as long as the fifth house has an open vent to atmospheric pressure

Indeed so. This means that the BCO has the final word on it, which is especially sensible given that no householder knows the Durgo/vent situation with the four properties downstream of him.It would depend on this situation, if there was ventilation at the head of the drain etc.
