If that's the case, he may need to replace the orifice inside the bypass outlet, or replace it with one size smaller...I've had that happen twice, where the hole gets worn slightly larger. The first time, I actually fixed it by cutting the end off a nylon hosebarb and sticking that in behind the bypass outlet fitting. Restricted the flow enough to stop the constant cycling. I didn't have a replacement orifice, and I needed to work! Try crimping the bypass hose with a pair of pliars a little, maybe 1/2 way. If the cycling stops, that's your problem.
