Ok,
here’s
my two pence worth…
If
you’re
messing about with plumbing (installing valves to turn on/off the water)
why
not install a ‘bath filling tap’ that has hot, and cold water
supplies, with an
adjustable set of taps on it (so the hot / cold flow rate can be pre-set,
so
the temp is just how you like it (I have a combi boiler so don’t risk
running out
of hot water) fit a valve, on a timer (be that connected to a small,
independent
circuit, or connect to a ‘ha controller / homevision / misterhouse
etc) (using
cat5 cable + relays to control the valves – maybe a similar principle
to the
chap who’s made his own garden irrigation
system)
And to
be
on the safe side (incase the valve goes t1ts up) use another fail-safe type
of
device which has been discussed
previously.
My
thoughts
/ reasoning on this are:
You
don’t have
to mess around with the workings exsisting, already working
taps
IMO a
filler tap looks quite good. – and could even be made out of some
chrome tubing
with a u-bend in it
You
don’t have
to use x-10 to look after it, you could use cat5 cable connected to the
relay
box and maybe an external low voltage supply (safer if anything
leaks)
I’ve
not
really sat and thought about this, because I’m going to take my bath
out when I
fit a new bathroom, and instead have a very nice walk-in shower
J (much more to my liking… IMO – better than
laying in a bath
of dirty water..)
Well..
that’s
my thoughts on it… and I tried to use ‘kiss’ (keep it
simple stupid)
Jonathan.

Hey, if it's good enough for F1 teams then it's good enough for me
