Is this wise?
Surely you could siphon the water out and thus avoid interfering with the house plumbing. I am in Hereford and have installed a system, not quite finished, utilising the house rainwater which will store and keep sweet, unlike bath water.Capacity to date approx. 320 gallons, could be extended.

You can buy a Greywater Diverter Kit from CAT. Go to www.cat.org.uk Click on "green shop" Type "greywater Diverter" in search box. Price £19.99. They are out of stock at the moment (I just checked)
That isn't a valve as such. It is just a rather sophisticated way of doing what you could achieve with a sufficient length of hosepipe which you will still need anyway, easy if your bath is upstairs.The big problem about grey water is that if you attempt to store it then it goes foul and unusable.
I suggest that you invest in an inline tap/stopcock to go on the end of your hose. Fill the pipe from the cold tap, close the tap, put the end in the bath then open the tap and the siphon will empty the bath until the end is above water level e.g. you have emptied the bath. The common way of starting a siphon is to suck the pipe but you would be advised not to do this with bath water.If you really want to keep the water you could try some bleach or a few crystals of potassium permanganate then leave it to clear but I would not guarantee its purity whatever you do.

how poluted the bath water is depends on what coloured , smelly stuff you put in it, if its used straight away going foul in storage wont be a problem, if you must store filter to remove lums then chlorine to kill bacteria would be a good start.
the actual plumbing depends on the layout and size of the bath waste, a good fish pond supply place should have all the piping and valves, try a search on ebay using , pond, fish, koi, etc for some ideas of whats available
