Dumb/Basic Pipe Reducing Question

We really need to know how many sprinklers and what will they be putting out for GPM each. And how far apart. If this is a small residential yard, With 4 to 6 rotor heads per zone, You will more than likely only use 1" for everything. Whats your available water pressure.

Rainbird 32SA will not pop up

Sounds like you have too many sprinklers on this zone. Try installing smaller sized nozzles or capping off a sprinkler or two that aren't needed. Or break the zone in two add another new zone. Check your pumping system- If you have a filter setup on your pump, Make sure it isnt clogged and the water is flowing through the filter.

Heads above valve?

I would steer away from the above ground Anti Siphon Valves. Replace them with any standard electric control irrigation valve. You can Bury them below grade in a valve box. These type of valves don't require any elevation change due to heads afterwards being installed higher or lower. You need to verify your backflow prevention device. Usually installed at the irrigation point of connection (IE At or near the Water Meter) The Backflow device is not electrically connected to your irrigation contr...

I have Leaking Valves

Sounds like you're getting trash in your lines that is clogging your valves. Are you on City water which is normally very clean. Or Well water ETC which can be dirty or grit in it. Take the valves apart and see if you see any debris in the body of the valve. Check the rubber diaghragm seat area for any pitting.

New valve won't close

Since your one valve system seems pretty simple there, I would just install a ball valve in front of the electric valve to keep it shut off

Comes on with no power

If your main controller is unplugged, you have a Battery Operated Controller somewhere (or another controller) tied into selected zones, my next bet too. Im interested to know what your service company finds when they come out, let us know.

Irrigation control valve box

Well, if the water has been shut off to the system, meaning you have physically shut down the water source to the system and the pipes have no pressure on them, (Example; water meter shut off or backflow has been drained, power to a Well shut off if you're on a well. ETC, you more than likely dont have a leak. If the water is still turned on to the system you may have a leak at a joint or a threaded connection at or near the valve. If your water is shut off and continuing to be present in the bo...

Zone wont shut off when switching to next zone

This is not a control box issue. (Controller) This sounds like a diaphragm or solenoid not closing properly. (Mechanical Issue) The valve will have to be located in the yard, and taken apart, cleaned or parts replaced. And if it comes down to replacing parts, you need to go ahead and replace the entire top end. (Solenoid, Bonnet, Diaphragm, & Seat.

Hunter MP Rotator side strip problems

You always need to use a PRS (pressure regulating model) spray body for the MP series nozzles. Hunter makes a body specifically for the MP nozzles regulating the pressure at 40psi MPR40 Look for the grey cap on top.

Comes on with no power

Well if they werent turned on manually by hand, then the valves are somehow stuck open, either by debris or mechanical failure. (diaphragm hung open) You will have to locate the valves and take them apart and more than likely replace the diaphragm and might as well replace the whole top end of the valve. (Solenoid, diaphragm & bonnett, screws, wire splices etc.) If you dont have any experience locating valves you could be in for a good bit of time wasted.

Can you wire two solenoid valves into one hot/signal wire?

Pretty much what everyone else is saying. Controller will run both valves electrically, but water pressure might be an issue. You probably have a cut wire somewhere in your yard, or a bad wire splice. You will need a Tempo (progressive 501) wire tracer and a 2003 Pulsar ground fault finder. If i had no experience with these tools, I would pay someone to come find the break.

Can a rainbird DV100 solenoid be found with a metal detector?

I have a schonstedt GA-52 and i can tell you it will not likely pick up valves. Ive tried. You need to go rent from your local irrigation supply house a valve locator. Either the Armada Pro700 or the Tempo 521, Either of these two will quickly help you locate the valve.

Comes on with no power

Could your valves have been activated manually. Meaning turned on by hand at the valve? Sounds like this is whats going on.
