How to further mod a sprinkler

[sanaka]

Anything is pissible if you just whip out your, uh, noggin and use it, dude. Even correct spelling. But some things are more 'complicaed'.



Sorry, couldn't resist...

Peace,

Filling from the top of the valve will also fill up the air reservoir.

How would I mod this one more?

I have starred at it for years trying to figure it out.

What do you mean 'mod it more'? It tells you how to mod it.

[jon_89]

I know but I have the valve with the guide rod thing and the solinoid in the center.

[MrCrowley]

Do exactly what he did, remove the 'noid, drill a new hole for the pilot valve, find out what you have to do to mod the guide rod (there are several ways posted on spudfiles somewhere) and then put it back together.

I have already modified the sprinkler but I want to "further modify it". I have modified it with a blowgun but I want it to hold "175 PSI with high flow".

[MrCrowley]

All you can do is mod the blow gun or upgrade to a better pilot valve.

They're not rated for 175psi, it would probably leak and I wouldn't even want to find out.

High flow? Well you can increase the opening time, but for flow you would have to modify the valve itself which would make it weaker, and defintely not safe at 175psi.

Okay this topic is "how to further mod your sprinkler valve". If you look at the eleventh picture down it says "The new version, capable of 175 psi, with loads more flow."

[MrCrowley]

Ah so it is, I didn't even realise.

I just suggest you open your 'noid valve up, and compare the two and improvise a way to do a similar mod. I thought you meant like grinding away at the inside to allow more flow, but then again I didn't even read the topic title.

[jon_89]

Yeah I keep looking at it then walking away to think and can't come up with anything. Would it be safe to 175 PSI though? It does sound kinda high.

Hmmm I've really gotta make me one of these. I've checked out a few different sprinkler valves around the place. I've noticed that with different valves, come different valve diamentions. Some have much deeper valve bodies which mean more room for the homemade phram' to shoot up to allow more flow. I'll have a fiddle and see what I can home up with.

In stead of using a blow gun i use a small ball valve, would that work better or give the same performance as the blow gun?

[grumpy]

a ball valve would most likely give you better performance cause it has a higher flow rate than a blow gun.

[jon_89]

Hey I just had an idea. If you take apart your blowgun and look inside you will see two small holes. Would it have better flow if you drilled these holes bigger?
