Hi there...

Please bear with me! I'm in a 1920's house with pretty old gravity fed
plumbing installed. The shower is OK, but not great. It was sugested
to me that I move the cold water to higher up in the loft to improve
the flow to the shower (it's not an electric shower, just a mixer
type). The cold tank is already about 4 ft higher than the hot water
tank. Will raising it another 3ft or so help any?

Would I be able to extend the pipes going in and waste out by using
something like tap extention flexible pipes? I have not soldered any
pipes together and not sure if I should takle something like that!

Oh, as if you didn't already guess, money is tight! (when isnt' it!?)

TIA

Have you thought about dumping the tanks, and fitting a double return
value [which costs a couple of quid] and running the whole system off
mains pressure.

Going back to your message: "The cold tank is already about 4 ft higher
than the hot water tank", do you mean 'hot water tank', I'm no expert
but in a normal setup you have:
- A large cold water tank which feeds the cold water taps + the hot
water cylinder, which in turn feeds the hot water taps.
- A smaller tank which is just used to top up your boiler/central
heating system and never comes out of a tap.

For a quick test. If the temperature of the shower is much better when
held 1" from the bottom of the bath, than it is when held 4' in the air
then yep that sounds like raising the 'cold' water tank would achieve
your aims.
