I noticed water under the 5 year old washer the other day, so disconnected it, tipped it over and quickly determined there was a pin hole in the plastic drain hose. Next morning saw me in a local hardware store where a replacement was sourced. Installation was a piece of cake, but the old style coupling to the drain under the sink in the next room was not sealing properly, so a trip was made to find a replacement sealing ring.
Apparently none of the stores within 20 miles of here carry the 1" diameter ring for the old style so I figured I should update to the new style with a standpipe into which the washer drain hose was placed to prevent reverse siphoning. Another trip supplimented my almost complete collection of ABS parts and once I was home I started cutting out old fixtures and duplicating.
Not too bad, but a dry test fit showed a bit of misalignment so back to the hardware store for another fitting. With that in place, everything looked good, so started pulling things apart in preparation for the glue up. That was when the drain broke off the bottom of the sink.
Another trip secured a replacement for the 44 year old part and things went fairly well after that, except for one of the pipe sections slipping out of my fingers as I tried to remove it from the wall. To retrieve it, it was necessary to make another hole at the base of the wall. After that, the glue up went perfectly. The machine just went through a cycle and all liquids remained where they were supposed to be.
