Hi Guys and Mary.

I live in a link-detached house (detached but joined by the garages).

My neighbours' garage roof is approx 2ft higher that mine due a slight
slope.

His garage roof drains directly on to mine, no gutters between and my
roof
drains into a gutter at one end.

If you can easily access it, connect a hose to it and backfeed into his
cistern. Water on the inside of his property will spring him to life. Just
remove the hose after a short period and any overfill will drain back out.
