After several purchases from your company, I am happy to report that they were all extremely pleasant. Not only did you stock exact items no one else had that I needed for a seventeen year old underground sprinkler system, but your prices were incredibly fair and far less than I had anticipated. Thank you for your prompt service and deliveries, as well. Phil C.

Lawn care made easy
I had to replace existing valves that had been in the ground for almost 20 years. The ones that I replaced had hardened rubber diaphragms and would leak. It is cheaper to buy the whole valve than the pieces.
They are excellent valves.

Works as designed
Easy install. Works perfectly so far ..... only just began the watering season here in NY. Nicely made.
I prefer the jar-top valves like this one.
Would recommend to others.

I have used Irritrol valves before- and this continues the reliable tradition. Irritrol valves are easy to install - they use threaded fittings so wrap with a bit of plumbers tape and you have a working system with no leaks- that is important to me because I have a drip system in my house for a planter and some house plants- so my valves are in my living/dining room- they have to be good and reliable!

My sprinkler system is by Irritrol (slimdial) and these threaded replacement valves with the solenoid will make it easy to replace the old system. In fact I'm moving the whole sprinkler manifold from under ground to the outside wall on my house and then build a housing around it with a panel door, making life easier as I get older. :-)) Thanks for your services.

My sprinkler system is around 10 years old using Irritrol 2400T-B valves. I'm thinking of replacing all 6 units in my box because at least 2 are leaking as I think they cracked last fall (late in blowing out) 1.) My current valves are 2400T-B. The "T" is threaded, but what is the "B"? 2.) My old ones have numbers on top of the cover that are 8,12,14,7,12,and 11. Are those significant when I order what I think I need in the 2400-T? 3.) I am having to run the system manually as the main valve to the solenoids has to be turned on and off because they leak. Does it hurt the solenoid to be run when there is not any water pressure against them? Thanks, Wayne
Wayne H on Jun 20, 2012
I have an 2400T value. Just replaced the solenoid and value gasket, but still have a slow leak where the water is still flowing to the sprayer units. I know there is a small gasket and the top of the bonnet and it is still in place, but there appears to be a crack on both side of the ring where this gasket fits. I remember reading that if there is no gasket or it is not in properly seated then the water will still flow. Otherwise the value works, just the it leaks (doesn't completely stop the water). Do you know what could be causing this very slow water leak? Can you just buy the bonnet along with this gasket if that is the cause?

can valve be operated in an upside down mode?
A shopper on Aug 8, 2017
Does this come in a right angle instead of a straight valve?
Tony F on Apr 7, 2012
BEST ANSWER: no, you have to add pvc pipe to make the angle
What is the difference between a 2400T FPT valve and a 2400S Slip valve both w/0 flow control?
A shopper on Mar 28, 2018
BEST ANSWER: Flow control simply will control volume of water going through valve. Not necessary in most applications. The flow control is “adjustable but fixed” so when the valve opens it can restrict volume. Personally don’t use the flow control valves.
Does turning valve off or on
allow manual flow of water?
A shopper on Sep 22, 2014
BEST ANSWER: YES twist solenoid till water flows or open little black screw slightly till water flows close to stop water flow. Newer valves have manual on off lever use that if yours has it like on irritrol 2400
How do I take the top of valve off and replace with new.. The body on mine is o.k. I need to know if this part comes "apart" so I can change only the top piece.. I don't know if it unscrews or what? I do not see any screws on either.. I don't want to take the chance on trying to "take apart" the part I currently am trying to replace.. Thank you
Todd S on May 19, 2013
BEST ANSWER: Be sure the water is shut off at the source before taking the top off. First, twist off the selenoid. Then the top of the valve can be twisted off by turning it counter-clockwise. Sprinkler Warehouse has a 2400-45 Irritrol 2400-45 Threaded Nut-Ring Wrench for $5.95 that works really great to remove the top.

If the hole fills up with water, you can complete the task but it is better to wait until it drains out so you can see what you're doing.

Now you can change out the top and everything inside without having to remove the bottom from the water lines. Take careful note how everything fits together.

Put it all back together and be sure to twist it back on nice and snug. Water pressure has a way of finding any loose or crooked connections.
What is the difference between the 2400T and the 2400TF?
A shopper on May 6, 2012
BEST ANSWER: The F stands for Flow Control. It means the valve will have an additional screw that allows for some amount of control over the flow rate through the valve when the valve is open. The 2400T does not have this capability.
sharp whining noise from solenoid when working and solenoid gets warm.can i get a breakdown of above model to understand valve better?
john n on Feb 27, 2012
BEST ANSWER: I installed 6 valves on a irrigation system for my son that is controlled by a pressure switch at 45 to 55 psi with no noise problems, I have a system with 14 valves for at least 15 yrs that has operated from 35 to 45+ psi, only problem I had was with sand when I put a new well down and a filter solved that problem. Question what is the flow and pressure that you operate on?

how to adjust the manual on off on ?
A shopper on Aug 26, 2018
BEST ANSWER: To turn the valve on manually, rotate the solenoid/bleed valve counter clockwise. If the bleed valve prevents you from rotating the solenoid, unscrew the solenoid just enough so that you can lift the bleed valve and rotate it clockwise slightly.
what type connection at both ends , i.e. female threaded ?
vince t on Oct 14, 2012
BEST ANSWER: This valve is availble with either Slip or Threads. The 2400T is threaded female and the 2400S is a slip connector for 1" pipe.
I have a 2400T valve. When I close the valve, either manually or automatically, some of my sprinklers still leak water very slowly. What can be causing this problem? Does it have to do with the washers, solenoid, or the bonnet? And how can I fix it? The sprinkler heads themselves seem ok, which is why I'm led to believe something is wrong with the valves.

Irritrol 2400F In-Line Valve with Flow Control 1
Irritrol 2400F In-Line Valve with Flow Control 1" FPT | 2400TF
BEST ANSWER: Hi many times the main sit on the valves gets crushed with the time, so the best call it will be, change the entire valve not just part of it. New valve is not that expensive.
are all 2400t valves the same parts?
A shopper on Apr 23, 2016
BEST ANSWER: Yes. I have replaced seals and entire valves in a 25 year old system with no issues.
where are you located? Can I pick up?
A shopper on Jun 9, 2016
BEST ANSWER: im in RI you can come over and pick it up but it's used now. Somehow this got sent to me
