The filters backwash drain was originally routed to a nearby utility sink. The new laundry connections were located between the utility sink and the water filter. Rather than leave the filter drain line surface mounted on the wall he decided it was better to make the connection as you see it in the picture. Clearly the handyman had no idea what the flow rate and volume of water would be when the filter goes into a backwash cycle; but they found out later that night.
they called me the next morning thinking there was a problem with the filtration system, which certainly was not the case.
thanks for stopin by,
