automated baths

[Stephen <yahoo@xxxxxxx>]

Hi,

I was searching the archives and found a thread about automating
baths, but I don't think there was a definitive answer.

Is there an automated filler, that switches off when the bath is full
or is it all timer controlled?

Can you automate the plug so that the bath only fills with the plug
hole closed? I realise you could use a solenoid valve, but the ones I
have seen are for 15mm copper pipe, not for 40mm waste pipe.

Thanks.
