A home owner nightmare. Ok you win on the 'my day sucked more then yours did' game.

I'm willing to share my shower with you.

PF's idea about getting water from your neighbours is a good one. Turn off your main water feed - otherwise the water coming in from the neighbours will go into the broken pipe. Some codes require a back-flow preventer on all water suppy to the exterior of the hosue - keep water from say you hot tub from siphining back into clean water. The back-flow valve will have to be remove.

Host a Pixies landscaping party, followed by hot tubing, drinks, and a BBQ. Just make sure the work is done before the play begins.

Don't let this wreck your weekend. Enjoy the event and the time together. Take a bath together???
