I've never had five solenoids go down at once, but Weather-Matic has been the biggest disappointment in solenoid history & has been reticent to cop to it. By rights, all these I replaced today should not only be replaced, n/c, but my labor should be paid, too. WM is warranting the solenoids, but Hank gets to decide whether to bill the client for my time. You guys replacing these p.o.s. solenoids with the S24BSAK...be very careful, it has brass threads & it's easy to cross-thread. Color me p****d off.
