View Full Version : Leaking head - need advice

First of all I only do lawn maintenance and don't know anything about irrigation. I do not plan on doing any repairs, I would just like to be able to give my customer an intelligent answer as to what is wrong and help them find a company to repair the problem if it's not repaired by my next visit.

During my last visit in the fall I noticed the leak and notified the customer that it needed to be repaired. Well I show up last month for a spring clean-up and it is still not repaired. He told me he had been trying to get the original installer to look at it, however a month later still no fix.

The leaking head is the second highest head on the lawn and is approximately 6-8 feet higher and about 60' from the 3 valve manifold. From what I understand the line should have no pressure until the valve opens for the particular zone (I could be wrong). The manifold box does not have a shut off valve that I can find. There are two green 8" covers near the main water valve, one that contains nothing :confused: and one with a ball valve. I shut off the ball valve and left it off for about 45 mins while I finished my lawn work and came back and it was still leaking at the same rate. It appears it is leaking directly from the top of the head around a small 3/8" brown cover with one screw. I would think with it being one of the highest heads the water would drain back down when no pressure is in the line.

Any idea what the problem could be? Bad head, bad valve?

Any help would be appreciated.

what kind of head?
is there a check valve in it.
ie does it leak when it is running or shut off?

I suggest telling the customer is a connection fitting ie a half inch funny L or a busted riser...possibly damged by a large lawn mower..is it by the drive way by any chance?

Its probably a seeping valve. The lower heads probably have check valves in them, so the water backs up to this one.

Me thinks the CAPT needs to be court martialed and demoted. This description is classic valve weep-by as it appears to be coming out the top where the sprinkler head riser contacts the top of the head. The screw is probaly the radius breakup. If there was something broken below the sprinkler head water would be leaking around the outside of the sprinkler body... NOT up the inside of the sprinkler riser and out the nozzle in a retracted state.

Sorry I guess I should have taken a few pics of the problem. I can't remember the brand name and I'm not familiar with the different types of heads. The best I can recall it is similar to the pic below if that helps any.

It is installed next to a tree ring with concrete curbing. I don't think my mower has ever come in contact with the head as I am very careful to stay away from the curbing with fear of damaging the concrete.

or is it a new system?

and is this the only sprinkler head that leaks?

Had your mower come into contact with it you'd know REAL quick as the sprinkler would only gush water when the zone valve is activated. A sprinkler leaking all the time is classic weep-by of the valve. The diaphragm most likely needs replacing. Sometimes they can be removed and cleaned if debris has gotten between the diaphragm and the valve seat.

Please enlighten us BUCK PRIVATE... IF you can put together an intelligent synopsis of the problematic sprinkler head and IF you can string together more than three words and make them coherent instead of sounding so much like your boozer boss. Stop acting like such a kludge.

The system is about 2 years old.

Yes, this is the only head that leaks.

Mr. Haze

Is the diaphram/cleaning a simple process or is this something I need to leave to the pros?

Mr. Haze

It's relatively easy. You need to first determine the specific valve by manually firing it and making sure that the problem "leaker" is on that valve. Then turn the water to the system of! Unscrew the valve bonnet (top) from the valve base. When you lift it you'll have the diaphragm and spring most likely come loose. Check for tears, warping, indentations and debris on BOTH the valve and diaphragm seat that is part of the body. You can clean it and replace it and give it a try. Sometimes the entire valve bonnet and diaphragm assembly will require replacement. Just go buy the same valve, tear it down and replace everything above the body.

If you take a decent picture of the valve and post it I'm sure someone will have prior experience with the same valve. They will also have knowledge of particular problems with the valve model if any are known.

No but Purp has idiot issues, he tends to be impatient with idiots who are trying to appear as thought they know something worthwhile. He also has issues with guys who give wrong advice and who are rude.

Any help would be appreciated.Since a R-50 was installed it might also have Dv-100's and it has a diaphragm that is weeping....high pressure like Atlanta has will kill a Dv-100 diaphragm...just a guess until we see a pic of the valve...

Good thought London..if he had low-drain checks & THAT one stuck open,
could be the problem, too..he did not mention how much of a slope he was on: I've seen low-drainage occur as the heads rose up the hill.

What kind of supply pressures do the Rainbird DV-100 series have problems with? It's rare that I get much more than 100 psi to work with, but I haven't suffered many high-pressure failures with the Richdel/Irritrol valves.

04-27-2007, 06:57 PM
We average 125-175psi...

Hey jar top.....I've been meaning to agree with one of your threads about
Hardie/Irritrol...a great company over the years....soon as Toro got ahold
of them, first clock down was the "Touch Command", the controller that,
if it had flow sensing...would still be a player.

Wet_Boots
04-27-2007, 07:09 PM
175? I expect you aren't subjecting the DV-100 valves to that much pressure. If I had much more than 120 psi, I might look away from the Richdel/Irritrols

Toro has actually 'corrected' some Hardie mistakes with the Richdel designs. Their 2500 valves sidestepped a flawed Hardie altering of the Richdel flow-control valve bonnet.

Consistent pressure over 120psi means a prv before the backflow in my book. I think the 2400's deal with pressures at or above 100psi better than most resi valves. The one draw back I have seen to the RB DV valve is it doesn't like higher pressures. The Hunter valves are worse yet. Even the better models HPV? Not going to look it up at this point. The SRV will crap very quickly at 100+psi.
