Following my thread #97065:

In an effort to keep a leaking vintage 1979 Maytag A608 alive I just installed an injector assembly. (The old one was leaking on fill. The whole thing was covered in mineral deposits from hard water and looked generally a mess.) But the leaking continues from the new. I believe during fill I see water oozing from the supply end of the valve, as though the flow is being partially blocked, and then dripping out of the plastic sleeve. Very little when filling on cold or hot, more so on warm, when there's more water pressure. So two questions:

1. The rubber valve that came with the injector set is 1/2" longer than the previous valve. It's also 1/2" longer than the plastic nozzle, which is the same length as the old nozzle and valve. Is this OK? Should I trim the rubber to match the plastic that goes inside it? Or do I need a different valve that might be the right length? Equally--or perhaps more--important, the lip of the valve is very slightly larger in diameter than the old, making it a little tough to fit it inside the supply hose. I can't tell if it's cramping up in there, but it may well be. Would these two size variations call for finding another valve in the hope it would be a proper match for the nozzle and the hose? How crucial to the operation are the measurements of these parts? Which is more likely the culprit, length of the valve or diameter of its lip?

2. The only thing I didn't replace is the plastic sleeve, because it's going to be a killer to get the old one off. (Rust. Hard to reach.) The new and old seem to match in the part that holds the valve. But is it possible that the old plastic is worn in some way that would interfere with whatever the whole thing is supposed to accomplish? I can't imagine but thought I should ask for completeness.

A long way of saying: Help!
 
Maytag dependable care, injector air gap still leaking

After you put the little plastic insert inside the new rubber injector sleeve I dip the large supply end of the rubber injector sleeve in liquid laundry detergent to lubricate it, and then you slide it into the supply hose, sort of twisting it at an angle as you put it in if you don't put the soap on it, it may pull off at the edges and then it will leak.

If you can't get it not to leak just disconnect the whole thing and take 5/8 inch piece of plastic or copper tubing and just clamp the hoses on each end of this section of tubing and just bypass the whole thing I've seen many people do this and the machine will still work fine.

I did moisten the end of the rubber with water and twist, several tries, but maybe I should give laundry detergent a shot. Any idea if the extra length of the rubber sleeve hurts in any way? Or do you think the extra diameter of the supply end of the sleeve is more likely the problem? In which case, if a better lubricant doesn't do the trick, I'll see if I can find a replacement sleeve that's a shade narrower (and probably half an inch shorter as well).
