|What are we talking about?
||How long does it typically take to replace
a ball valve in a tank? Usually in the loft
||Up to 1 hr
||Being able to turn the water off
|Questions to ask
||Is the stop cock working? Does the customer
know where the main stop cock is? Make sure the roof tank is accessible
- having to fight a way through lot's of 'stored' items will lengthen
the job. Double check the location - in some flats the cold water
storage tank is on top of a hot water cylinder.
Replacing a ball valve is a simple task as long as the water
to the valve can be turned off and there is ready access! Normally
turning off the supply at the stop cock is required.
Stop cocks are the culprits which can turn this simple job into
something longer winded. In many cases, particularly in hard water
areas, it's just as simple to replace the entire ball valve mechanism
than just the washer as the cost of the mechanism is small.
Remember that if there's no light the plumber or handyman will
have to supply some.
