another little problem on my 85 hilo....under the kitchen sink there are two 2 inch 90 degree abs fittings coming up from the grey tank.....they are both broken...my guess is the grey tank settled a bit over the years ...my question is are the two 90 degree fittings glued into the grey tank or just a tight fit?...i dont want to break the tank trying to get them out if they are glued in....has anyone else run into this problem?...thanks in advance

I would think abs glue was used in the original construction. Just last week I came across a similar problem with the vent pipe in the bathroom. The pipe is sandwiched in the wall between the bath tub wall and refrigerator wall and broke at a "Tee" fitting. There is not any way to repair it without taking out the bath tub and removing the wall. I did a temporary repair with abs glue and Flex Fit duct tape (not the cheap grey duct tape).
