one head is lower than the other, but what is strange is that when I lift out the spray tube of the lower head there is not enough leakage to come up to the top, plus only these two heads are leaking. A true sprinkler mystery. BTW what is low sprinkler drainage. thanks paul
I tried the emory cloth and it all looks fine but there is still a small leak from two heads. I guess i will replacle the whole valve assembly?
I have two leaking heads in the lawn from the same 3/4 brass champion valve. I read that the problem was probably the diapharagm so I bought a rebuild kit and replaced the diaphragm,seat and o-ring on the solenoid and the leaks are still there. Any advice?
