Why not put a door into the laundry from the toilet as well?
I see 2 advantages. You can access the toilrt from outside without coming into the kitchen. The other is that you don't have to go outside to put dirty clothes in the laudry.
My wife would be most upset if she had to go outside all the time to check the washing machine etc.. :D
I don't have my copy of the BCA handy. (Like Stinky, it's in the office.)
Have a look also at the performance requirements at the start of that section of the BCA. Many of the deemed to satisfy requirements are not as precise as they ought to be, and need to be read in conjunction with the performance requirements in order to really nail the answer to the problem.
In addition to being switched on while the sanitary compartment is occupied it is a good idea to fit one of those time delay switches, so the fan runs for a period after the compartment is vacated.
Another alternative is an exhaust fan system that exhausts the air via the flushpipe. There was a product, called Wilcovent I think, that operated on this principle. It got rid of the stink before the whole room got ponged out.
The Performance Provisions do not add much.

The Objective is to safeguard occupants from illness or loss of amenity due to lack of air freshness.

FUNCTIONAL STATEMENT
F2.4.5 Ventilation
A space used by occupants within a building is to be provided with adequate ventilation consistent with its function or use.
I agree with adding a time delay switch as good practice.Quote:
PERFORMANCE REQUIREMENT
P2.4.5 Ventilation
(a) A space within a building used by occupants must be provided with means of ventilation with outdoor air which will maintain adequate air quality.
(b) A mechanical air-handling system installed in a building must control—
--(i) the circulation of objectionable odours; and
--(ii) the accumulation of harmful contamination by micro-organisms, pathogens and toxins.
(c) Contaminated air must be disposed of in a manner which does not unduly create a nuisance or hazard to people in the building or other property.
I worked for a home improvement company for a while and they had a product like this, sucked air out of the flush pipe and vented out through 40 or 50mm PVC waste pipe, I can't remember which. I do remember though that it only shifted about 40L a minute and was really aimed at the home improvement market, rather than meeting the needs of the BCA in regards to this application.Quote:

Forgetting the regs, the result was very good coz it was right on the kitchen/breakfast bar. No plops or trickles :D
I appreciate it's an investment property but short cuts might well lead to short tenancies :rolleyes:
