I am making an application for a new water connection (new build). All
was going well until the form got to water regulations and requested a
scaled schematic of what and how we intend to distribute the water in
our house. My application is respective to a supply that will initally
be used for a static caravan (whilst we build), and then for use
within the house. We havent even decided on the plumbing design or
plumber to be used yet, so how can I put these drawings together?

Does anyone have / link to an example of what is required?

Thanks!

You could try just saying some standard stuff about check valves, trap
depth and vented soils stacks.

From my reading, not much of the regs apply to domestic installations,
and none of them are particularly onerous.
