Ideas for bringing water at the rear of the house

Hi Symeon. Clearly, you have many elaborate and expensive choices... however, if you have a sideway then just get an extra long hose. If no side way then for occasional use perhaps you could just run the hose through the house... obviously with no joins. Just an idea. Bob.

The loft space is always useful to run a supply from - if you can get a pipe into the roof space them it is easy to run it to the rear

going over the roof is a bad idea better to take a pipe up through the loft or if possible under the floor

Copper pipe or poly could be ran up from cold water source at front up through to loft across and down or under floor , or around the side of the house and all would have to be insulated but running a pipe around the house against the wall would mean it would need to be definitely isolated at the start from the source because you’d need to turn off the supply and empty during the winter months to stop freezing and splitting/ bursting of the pipe.

The best way would be either to take it from the internal stopcock, channel it out 2 & half feet deep & run it to where it needs to be. It’s never a good idea to run cold feed pipes on any surface because of frost
