Water pipes

[glyn1206]

I've got a job to lay some water pipes to three greenhouses and a shed,problem is I aint no plumber!
Can anyone enlighten me as to what size pipe I need?
The run is about 50m from the house max,I assume that if I were to connect to the house supply(15mm)and all three taps were running at the same time the pressure would be next to nothing ,any ideas?
I also need to run some lecky to the same buildings can I put the cable in the same trench (armoured cable)?Thankfully there will be a sparky to sort out the connections

you want the blue water pipe,but this really needs to come from the rising main,if you take it from a 15mm pipe pressure will drop,needs to be buried to a frost proof depth

as for the electric armoured cable yes,but the sparks needs to determine the loads on it so you know which size to get

with the water pipe better off getting a waterboard man to do a foreigner and mole it for you,lot less aggravation

pipe to use is 25mm alcathene needs to be laid at 900mm deep . comes in 50 mtr rolls so should do your run. you can put elec in same trench but lay it in ducting:)

Or at least put some electrical cable below tape over it before backfilling.

I would put the water at 750 and duct the electric at 350 to 600. sand the run and put water and electric duct tape 150 above each service, or 150 at least below ground level.

thanks guys,
I was going to lay the water at a lower level and put the lecky higher up ( as suggested)
I was going to use a trencher as I will be laying a pathway/roadway on top (edgings/mot 1/chippings)later
thanks again to all
