Clue to Puzzle #26: Gas, Water, Electric to 3 Houses

gas water electric puzzle layout26. A man has built three houses. Nearby there are gas water and electric plants. The man wishes to connect all three houses to each of the gas, water and electricity supplies.

Most people will get as far as the picture below. That is two houses connected to three supplies and one house connected only to two:

I will willingly concede that the next step is a bit of a cheat. But can you see a path for connecting the second house to the gas supply that doesn't cross any other supply line?


Where next?
