OK,I have a Toro Custom Command Controller that was given to me for a great price.....read FREE. I will now need to buy valves. This is for my own home,so,I am looking for a quality valve.What model would most of you reccommend?

One of the guys at my supplier said that he likes Irrotol.He also said that they are all the same,but,I have a hard time believing that. Then again,he sells all brands,so,I want to see what most of you say here.

Thanks in advance!

Irritrol 2400 valves will still be repairable when your great-grandchildren are playing in your backyard.

I install mainly Rainbird products. The valves at my house are Irritrol 2400s....

Those were quick replies,thanks Wet and Bob! When I purchase the valves,what is the best configuration? The irrigation guy at my neighbors house has valves with female threads at both ends. Which type ends would you reccommend? I would like to be prepared should I have to repair or replace a valve in the future.

I will be making a manifold and will post pics for your entertainment.:)

I always use female threaded valves and use a close nipple into gasketed fittings for the manifold. On the output side of the valve, I use a Turnseal fitting. This allows me to easily take a valve body out if need be.

Bob,when you say Turnseal,are you talking about an expandable compression fitting such as those used to repair PVC? I ask because I have never heard of Turnseal.

A turnseal fitting connects to poly pipe and can be tightened/loosened by hand. Very handy for working in tight quarters.

I'm assuming (quite likely, incorrectly) that you are using poly pipe instead of PVC. I'm not sure what is used in your neck of the woods, but the general sort of pattern that I've noticed is manifold people are generally poly people...

Bob,the manifold will be PVC while all other lines are poly.

OK,I will get the 2400's based on your advice. Should I get valves with or without flow control. What exactly does flow control do?

Make sure the valves have a flow control on them.

I would go with Weathermatic. Only valve with a "bleed screw" that bleeds internally so not to flood the valve box.

Use threaded valves, makes easier for repairs.

The irritrol 2400 flow control isn't the easiest to access. I'm a RB DV with flow control man myself. Pretty much all the valves except the Irritrol 205 have internal bleeds.

Unfortunately John outside the Smartline and brass nozzles you aren't going to get a whole lot of support for the WM product line. I've got a system on McFarlin that isn't even 5 years old with sticking WM popups. Albeit all heads have this problem to one degree or another but some have a higher frequency from experience and WM is one of them. My head of choice is the 1804 sam. With the spring they put in that popup you aren't going to get very many stick up problems. To me a popup has this job. Popup and spray then drop back down flush. I'll use from experience the one that does that on the most consistent basis and that is the RB 1804sam. If popups were humans I'd have fired the irritrol HS 4, WM LX4, Hunters SR, Hunter professional, Hit heads, Toro, RainPro.

One head from way back I will give major Kudos to is the HydroRain 4.5" that used the champion nozzle. I've got properties with those that are 30 years old and they still work like CHAMPS!

1804, seem to stick a lot around here . I like ps sprayers when applicable if not Hunter pro sprays seem to stick up less then 1800,s. A lot of that could be that the majority of our spray heads are along driveways that get sane carried into them from cars picking it up on the roads in winter.

Try the 1804 SAM. I agree that the normal 1804 has its stick up issues. Not as bad as those I've mentioned but probably not any better than the Hunter pro. The SAM version requires 30 psi to push up and can hold back 14' of water.

The Hunter Institutional is a near equal to RB1800, and a bit cheaper as well.
That said, I still use mostly 1800 SAM and 1800 PRS-SAM

I never ealized a sam has a stronger spring in it. duley noted. ( sp? )

Also has a o-ring in the cap to prevent those friggin cap thread leaks.
I noticed in the last L&I magazine that Irritrol looks like it is launching what looks like a RB knockoff as its new popup.

Take out the springs of the HI and compare to the RBs. I used some Hunter I 12" popups and was not impressed compared to the RB 1812sam. The HI 4" seem to be holding up well on one property I used them on as a test.

So,I went to my supplier today and bought a rain sensor,fittings,13 strand irrigation wire,and valves. I took my list out and asked for 8 Irritrol 2500 TF valves. He asked me a few questions and said I do not need flow control. He said I would have no problem with the Irritrol 205T valve..lol.

I said fine and took them. What is your opinion on this because I can always take them back before I make the manifold. Choices,choices.....:cry:

Unless it's a ton of money, get flow-control valves. You probably can do without, but they are the best you can get.

Quick update....Went to supplier this morning to return the Irritrol 205T valves and asked for the 2500TF valves. He looked at me funny and said."you mean the 2400". I said no,Iwant the 2500TF. He said they didn't carry that model,so I said,ok,just credit my credit card for the 205T valves I am returning.

I then came home and odrered the 2500 TF valves online. They were $17.41 apiece.

I thought the 2500 series Irritrol valves were an upgrade over the 2400 series? Is that right or wrong? I dont get why they do not carry the 2500 series valve. :confused:

Pros who don't believe in standing the expense for flow-control valves would rather buy the 2400 standard jar-top. I liked the 2500TF for having a flow-control you can put your hands on, besides the kind of bolt-on cover you'd want for high pressure.

It will be the DIY crowd that will sometimes have real need of flow-control valves, because of one or another oversight in their design work.

I prefer valves with no flow control, I've had less problems with them and you don't get people jacking with them.

So,with the flow control,you can adjust up or down for more or less pressure?

Wet_Boots
06-30-2008, 10:18 PM
Two main benefits - you can reduce pressure and get better operation, on a zone-by-zone basis. And a partly closed flow-control valve is far less prone to sticking open.

GPM's but you shouldn't need to adjust them and they are easily effected by temperature.

Oh boy,what did I get myself into? :hammerhead: lol........So,when I get them and install them,do you suggest I leave the flow control as it comes from the factory?

Ever adjust a carburetor idle screw? Same principle. Throttle down the valve until you affect the flow, then back off half a turn.

I sure have wet....sounds easy enough.....can't wait to install them.Let me share with all of you as to what I am doing.

As stated,three years ago,I installed irrigation for the beds only(plants & flowers) because I was tired of watering everything for 2 hours when I got home from work. I installed a 3/4" backflow preventer which goes to 1' PVC followed by 3/4" poly which goes to each zone in various beds on the property.There are 6 zones and each zone has 5 or 6 Toro 570 spray heads.Are you ready for the funny part?:cry: Each zone is operated by a valve that I have to turn on manually(ball valve). It seemed like a great idea then and I could kick myself for it now,but...whatever.:hammerhead: So,Now,I have decided to change everything over to electric valves. Actually,it won't be that bad...a little more digging,more poly,disable manual valves and install new ones. Piece of cake...:)

This winter or in early spring ,I will add zones for the lawn and that will be the end of my irrigation carreer.:clapping: I want to thank each and every one of you who replied to this thread!!!!

Hey,would you like to see pics of my manual valves? I will take pics and post them in a couple of days.

The art of multiple carburetor tuning was in the hearing...a hose was inserted into the carbs & you listened for the difference. My Jags & Rovers had SUs & tuning was tricky. The most fun must have been the triple Strombergs on the six cylinder Corvette.
