Master Valve Won't Open With Controller or Manually

A resistance test of the valve wiring would be in order. Reading voltages alone can be misleading. Also, double-check the water supply shutoffs - all of them. Sometimes the sprinkler system itself is in proper working order, but a gate valve further upstream can be partially closed.

New Install - Flow Rate/Pump Problem - Need Advice

Since the cycling is caused by a pressure switch on the new pump, there was always a simple solution (maybe more than one simple solution) Simplest solution part 1) Restore the system to the original zone layout. Undo all the modifications that created uneven watering. Replace the too-big pump with one of the proper capacity. Swapping the 1 HP for a 3/4 HP comes to mind, but the original pump might have been even smaller. Simplest solution part 2) Take the cycling out of the picture by taking th...

Valve maintenance, check valves, anti-siphons and water pressure

the RPZ is elevation-proof, and can be downhill of the sprinkler system, unlike antisyphon valves - it is also rated to protect against toxic backflow, which is the going highest standard of backflow protection, and why I give it as the one choice that makes other factors irrelevant

Brand new valve, brief water leak upon valve closing

Just as general advice on antisyphon valves, the brief outflow of water at zone shutdown is not an indicator of malfunction. Spring-loaded rotor heads with modern wiper seals are apt to do this sort of thing, as the springs in the heads push water back at the valve. Spray heads have much weaker springs, and don't push back as much.

Valve maintenance, check valves, anti-siphons and water pressure

Exactly. The RPZ goes upstream of the rest of the system. You would eventually replace the antisyphon valves with conventional inline valves. You are also correct that the RPZ name is not connected to system zones. It refers to the portion of the assembly where the water pressure is reduced from the supply pressure upstream of the RPZ - it is this pressure difference that creates the physical force that closes off the water outlet built into the RPZ. A further note on water drainage from zones. ...

Rainbird ESP modular tech added an extra zone?

It wouldn't hurt to double-check the backup battery on the controller. 10 minutes is a common default setting for zone run times, and it can appear after a power outage on controllers without backup power.

RE: Valve maintenance, check valves, anti-siphons and water pressure

Quoted from "TrippKnightly" My valves are downhill from almost all my zones Then your sprinkler system has no backflow protection. The question becomes why on earth do you you want that? Absent a location for this system, the only "one-size-fits-all" remedy is a reduced pressure principle backflow prevention assembly (the old self-explanatory name is better known today by the abbreviation RPZ) You have to spend some money for the RPZ, but it gains you plumbing code compliance, which is a nice t...

Zone very low pressure, valve or leak?

Quoted from "Jdotbuch" ........I have thoughts about just cutting this all out........ Now you're thinking. Useful recommendations about what Orbit valve(s) to install are hard to come by, because pros don't use valves that can't be repaired on account of no local sources for parts. Just for grins, photograph the all the valves in the system. There is a plumbing layout that would prove useful if you could never get any zone valves other than Orbit.

Voltage drop

There is a way to trace a nick in a wire, but it employs some complicated instrumentation that takes time to learn how to use. For the least amount of money spent, the homeowner solution to wiring issues in the field is almost always to dig in a new cable, with spare conductors for future issues.

Valve Identification

Quoted from "mrfixit" .....Strange that the metering pin isn't in that diagram...... there are some of the Toro 250 series electric valves where there is no metering pin - they had a slightly different diaphragm assembly, with a fine-mesh filter screen on the diaphragm to protect the metering orifice on the assembly A factor to consider on these valves when they develop body cracks, is that every one of the 250 series valves in the system is liable to go the way of the first cracked valve. Ther...

How to Connect Supply to Manifold

Megaloc works on pretty much any pipe material. Since it doesn't harden, don't slop it so heavily that it gets into the system. (and given what it costs, you won't want to overuse it anyway)

Grass Runway/Airstrip Design...Need Help!

Are you sure you don't want to wait another seven years? You might have the runway paved by then. There is one unavoidable bit of work that must be done now. The flow rate of the well must be determined. This is also known as Recharge Rate. You must try to pump the well dry. A pump with a shut-off valve on the output, with sufficient capacity to empty your well, is what you employ for this. Once the water level drops to the point where your pump is about to be sucking air, you throttle down the ...

How to Connect Supply to Manifold

The photo doesn't quite make obvious what the copper plumbing terminates with, but there are two different methods employed, depending on whether the copper ends with female threads or male threads. But before you get into that consider using an upgrade in pipe thread sealant. Teflon tape is usually fine on its own, but to take it up a notch, get some Megaloc at Home Depot and redo the transition between the copper and PVC.

Update old system

You should first determine what the water flow is in each of your zones. Then you can make an informed decision on replacing an indexing valve with individual zone valves. The idea is to not wreck the system performance with additional pressure losses from zone valves replacing the indexing valve.

Sprinkler system design

Quoted from "ls73" Quoted from "Wet_Boots" Only a pressure vacuum breaker (PVB) provides actual vacuum breaker protection when feeding any sort of electric valve(s), and they cost real money and plumbing effort to install. It's worth the effort to do the plumbing right. The only thing that should be connected to a faucet-mounted timer valve is a hose and a hose-end sprinkler, all above ground. This is exactly what I am using. "Mueller/B & K 108-904RP Backflow Preventer-Vacuum Breaker" No it is ...

Sprinkler system design

Quoted from "mrfixit" What about something like a DIG battery operated ASV? ASVs are the thriftiest way to get real backflow protection when using a hose bib as a water source. One for each zone. Separate controller and standard ASVs would be cheaper on a 4-zone system than going with battery-operated ASVs. This involves some real plumbing, in order to get a result that isn't flimsy, but nothing about is impossible.
