Rainbird Weather sensor winterize?

Hi, I'm wondering whether I need to do anything to winterize the weather sensor - it's a Rainbird ESP-SMT weather sensor, connected via wire to the controller. I saw that Hunter recommends removing any water from the cup and covering with a plastic bag, but couldn't find any guidance from Rainbird on their weather sensors. Any help is appreciated. Thanks

PVB winter removal

I know it's not necessary with a properly drained system...that said it has unions just for this purpose. Also if I needed to take it out for some reason it would be good to know that I can remove it. Quoted from "SunCoLawns" Why bother taking it out? If it is properly drained it will be fine over the winter.

PVB winter removal

Hi, I had the plumber connect copper unions when installing the backflow; I couldn't remove the PVB today however. I was able to loosen the union nuts on both sides and was able to disconnect on the outlet side but couldn't disconnect on the inlet side. I tried putting a block against the underside of the PVB and hammering to loosen but didn't work. Anyone ever run into this? Thanks Dan

2nd blowout in same season?

Thanks for the follow up, I figured since the guy has been doing this a long time and works for a reputable company the job he did was probably fine. I wanted to get a few extra weeks of watering from the sprinklers, it's been tough to keep the newly sprouted grass watered. Quoted from "Wet_Boots" Repeats aren't necessary. An operator using a smaller truckmount compressor might opt for a repeat on selected zones. Always, they are looking for heads popped up and blowing air/mist. Mist is okay.

2nd blowout in same season?

Anybody? I was thinking Friday Nov. 20th or Monday Nov. 23rd would be possible blow out dates that would work (the long-range forecast in Massachusetts Metro-Boston area doesn't look very cold). Also, the company that blew out the sprinklers used a compressor that sat in the bed of a pickup truck (said it was their back up compressor). I didn't ask about the volume of the tank but I thought generally the tow-behind compressor was the size needed to do it right.

2nd blowout in same season?

I had the sprinklers blown out last week and have had to do a lot of hand watering for the newly seeded (4 weeks ago) 15K sq. ft. of yard. The majority of the yard is in the shade this time of year, but still the hand watering is very tough to keep up with since I'm still at the point where I can't let anything dry out (light frequent waterings). I live in Massachusetts, forecast is pretty warm the rest of the week, and the meterologists have indicated no polar air mass to lock in any lasting co...

Leaking Rainbird SAM PRS 1804's

UPDATE: I picked up a few extra 1804's today, but I'm not sure the heads are the issue, there's some problem that's affecting the zone itself. One or more heads on this zone leaks at all times. If I "fix" one head, then one or more other heads start leaking, and then I fix those and the original leaking head is back to leaking again. The zone otherwise operates normally and I don't see any issue looking in the valve box, but I'm guessing it may be an issue with the valve internally, maybe I shou...

Leaking Rainbird SAM PRS 1804's

Quoted from "Wet_Boots" just swap out the heads and examine the faulty ones at your liesure Yea I figure, just no backup head at the moment. Haven't had any issues with any of the many Hunter PGP's yet but several Rainbird 1804's have been a nuisance.

Leaking Rainbird SAM PRS 1804's

Has anyone had problems with Rainbird SAM PRS 1804's leaking? On a couple of them I am having an issue where the top of the nozzle doesn't quite sit flush on the head body (i.e. it doesn't close 100%), and then water trickles out continuously. I tried fixing one recently as I saw there was a pebble or two inside the head body, so it wasn't allowing the pop up stick to close properly, but it's leaking again (maybe something else got inside). Another head was spurting open every 6 or 7 seconds a l...

Winterization blowout

Great, sounds like a plan to get through the cold nights ahead. Thank you much. Quoted from "SunCoLawns" If you've turned the water off, opened a drain before the backflow, opened the test cocks and opened the master valve bleed, it really isn't necessary to take the backflow off. Pipes below ground should be fine for the weekend.

Winterization blowout

I took your advice and rescheduled the blowout for October 28th. I will drain everything above ground this weekend - downstream of the PVB I will drain the bleeder on the master valve so that all the water above ground drains well. My PVB has union connections so I could take it off at night this weekend and bring inside if I wanted. Wondering if I should still try to run some water through the pipes during the daytime hours or just shut if off for the whole weekend? Thanks

Valves wont open automatically

Took a second look this morning - looks like one of the common wires didn't get spliced in at the master valve box, I bet this will fix it! Update: Yes, splicing in the remaining common wire fixed it, all zones are up and running. Thank you much for the help.

Valves wont open automatically

Thank you both for the follow up. I finally had some time to look into this and bought a multimeter to assist. I'm able to get 8 / 10 zones to work fine through the controller now. The first two zones and master (which all run on one wire) are still an issue, so for now I left the master valve open so the others will run. I have power from the transformer to the controller and from the controller to the wires for these valves, but when I run a continuity test the multitester doesn't even registe...

Winterization blowout

Update: I fixed the solenoid that was stuck (actually worked just fine I think I was reluctant to give it a little torque when I first started the system up). I also was able to get 8 / 10 zones to turn on via the controller. I will post on that on a different thread, thanks.

Winterization blowout

Thanks for the follow up. The companies in my area said they regularly winterize sprinkler systems until the end of November every year, and yes I figured the backflow was probably most in danger from what I've read. I guess I'm being a little overly conservative, but when I heard the weather people talking about potential for a hard freeze and knowing a few of the pipes are very shallow I didn't like that. Trust me I'd MUCH rather keep working on the system and having it available and not have ...

Winterization blowout

Hi, Given the potential for a hard freeze this weekend in Massachusetts and given that the poly pipes running underground are only a few inches deep in spots due to rocks underground or line crossing, I scheduled an irrigation co. to come out on Friday afternoon to blow out the system even though I had hoped to keep tinkering with it for at least another week. The issue is one of the 10 zone valves won't open unless I open the bleeder screw. Since this option won't be available to open the valve...

Valves wont open automatically

Timer and all valves are wired up, so the valves don't work through the timer - i.e. if I leave the solenoid tightened (closed position), bleeder screws closed, flow control open (solenoids on downstream side of valve), and then tell it to run zone 1, 2 etc. nothing happens. Quoted from "SunCoLawns" I'm not quite clear on what you are asking. Are the valves not working through the timer, or do you not have the timer hooked up? The valves should all be closed with their bleed screws and solenoids...

Valves wont open automatically

Yes, its a Hunter ICV 101G, it has female threads on either end. Quoted from "Wet_Boots" It's a threaded-body master valve?

Valves wont open automatically

Yes, confirmed. Quoted from "Wet_Boots" Just to head off any wasted time, confirm that you didn't install the master valve backwards.

Valves wont open automatically

It is connected and works - if I manually close the master valve solenoid no water is available for all downstream valves. What is the normal operation when using the controller - does the solenoid actuate itself from the off position to the on position to open the valve or does it stay in the off position and operates the plunger without physically moving the whole solenoid? Quoted from "Wet_Boots" Why isn't the master valve solenoid connected to the controller?
