Been to a customers today to price laying a patio.(great weather
)The customer has already laid the base(solid concrete, 12 inches thick!) and underneath has run the swa to feed his shed.(2.5mm only)
The swa is to be jointed into the utiliy room ring via a fcu,on this dedicated ring is washing machine and tumble dryer.Measurements as follows:-
cu to fcu point=15m
fcu to edge of patio = 4m
patio to shed =20m
All the elderly chap wants is to run 1 light and 1 double socket for his woodworking hobby,nothing to serious at all.
Question is,would this set up be alright for the full length in 2.5mm?
If not, could he do an external/underground joint from the edge of the patio and joint the 2.5 to two 2.5's (he has got enough left over,so therefore making the 20m run from the patio to the shed 5mm)
If none of the above look like a good idea then i'll have to do what i don't want to do,dig up his concrete base
Please bear in mind i'm only a humble brickie so if none of my ideas sound sensible,dont shout to loud!
Thanks in advance.
