Default Plumbing outflow of washing machine into external drains

Hi

I've recently plumbed a new washing machine into the garage and need
to run the outflow pipe through the garage wall foundations, into a
trench, then run it along for about three feet before connecting it
into the the drain where one of the downpipes flows from the
guttering in the house. My problem is that I'm not sure how I can
drill a core into the concrete gully to fit the outflow pipe without
cracking the gully. I'm also not too sure how to get though the
garage wall. Any advice?



Where does your surface water go? It may not go to the public foul
water sewer - it could be that it goes to either a soakaway or a
surface water sewer! Hence the connection would be both illegal and
polluting the environment. This home modification is often the
greatest source of pollution in urban watercourses!


I had a customer last week wanting a washing machine installed into an
attached garage. He seemed sure it would be OK to discharge the
waste into a surface water gully. I told him it wasn't suitable or
legal. I suspect he will get it done anyway, so I have my
principles, but I lost the job!


Sorry you lost the job but it will protect your reputation. You never
know, he might just be persuaded of his error by another and come back
to you if "The Price is Right".
