|What are we talking about?
||How long does it typically take to replace
a tap or just change the washer?
Tap washer from 20 minutes
Tap cartridge from 20 minutes - warning: there are over 200 types!
Basin taps from 1 hour
Kitchen / bath taps 2 to 3 hours assuming reasonable access
||Being able to turn the water off
|Questions to ask
||Are there isolating valves? If not does the customer
know where the main stop cock is? Is there a roof tank (in older
properties some upstairs taps were often fed from the roof tank).
For bath taps check the taps are NOT at the far side of the bath
between the bath and the wall and that the bath panel is removable
and not tiled / has floor laminate up to it.
For hot taps the inlet to or outlet from a cylinder will probably
need to be turned off by way of a gate valve (usually red) and
these often fail if not maintained.
Where there is a combi boiler the hot water can be turned off
a the boiler. Where there is a pressurised cylinder the hot water
can usually be turned off at the cylinder.
In hard water areas taps can sometimes be 'reseated' but if they
have been dripping for some time they are best replaced.
