PVC Watering Grid.

Post  Hoggar on 4/3/2012, 3:22 pm

My Watering grids.
I have one for each 4 X 4 box and there connected to each
other with a short section of hose and a Brass 2-Way Connector which I use
to adjust the pressure to each grid, it then is connected to the faucet and a
battery powered timer with another Brass 2-Way Connector.
I ended up using Full pattern micro-Sprinkler spray heads. I have
tried many different types and will keep experimenting until I'm happy
with the output. I'm thinking I might switch to Soaker tubing and a
4-Port Adjustable Manifold to keep the water off of the leaves and down
in the soil.


So here is the recipe for the grids if any one is interested.

I bought 1/2" PVC tubing and cut it into

18x 10-3/4" lengths
6x 9-1/4" lengths
2x 2-2/1" lengths

I used
9. cross connectors

2. 90° Elbows

1. PVC Reducer Male Adapter 3/4" MNPT x 1/2” Slip.


2. Male Slip Adapter 1/2" x 1/2"


2. 1/2" Threaded cap.

9. Slip on PVC caps.

for each grid




The timer assembly parts are:
A double nozzle faucet timer.
2. short lengths of double female ended hoses.
1. Brass 2-Way Connector.
1. 3/4" Double Male Brass Water Hose Coupling



This setup allows me to run the water system twice a day.

I will up date this as I make changes.

That's an amazing grid, for the nozzles have you looked at the under soil drip systems instead of soaker hoses? I saw some of the nozzles for it at a local irrigation store last year, and they screw into the same areas as the micro-sprinklers.

Just a thought,
James

Ps I would love to see pictures of it in action!

I keep coming back to this thread because it makes so much sense to me in how it's set up. When we put our sprinkler system in years ago, we had two zones set up for drip system and had intended to set it up as such, but changed our minds or just never got it going. But we did buy all of the 1/2" hoses so I have 5 or 6 rolls of it and a few rolls of the 1/4". If I do this, I would probably use the hosing I have and put in drip heads. You mentioned you've tried several experiments prior to arriving at this one. Anything that stands out that definitely didn't work? Any downsides you've come across in having a grid like this? I'm trying to weigh options but weigh more heavily on the supplies I already have. Smile

I'm in the process of re jigging the green house irrigation as the stuff I had previously was just not up to scratch .

You had no control at the drippers , it was the very devil of a job to set the flow just right so they dripped sufficinetly along each 12 foot branch of six drippers .

This new set up has a computerized controller like the others but is settable for all sorts of intervals of watering from a minute to several hours of water on , gaps every few hours if needed , it can be set to which ever day or days in the week to do all sorts of timings .. some thing like 20 events per day if needed .

It uses 1/2 heavy duty PVC tube as the man water arteries and branchese off every 18 inches over 20 feet into heavy duty 4mm tube to anjustable drippers or ..get this .....an adjustable spray head that can be 180 or a 360 degree coveraege with diameters from 1 foot upto almost 20 inches per spray head.

They were special offer ( due to water restrictions in the UK ) at less than half price , P & P free .

So we got two sets and saved over £70 . The company must have a hell of a lot of them in their stores to rack them out at that price.

The spare bits plus and extra 50 mtrs of 1/2 & 4 mm more tubes & sprays /drippers will be added to to make up six hanging basket watering pionts and also to run several dripper and spray heads to each SF bed over 1/2 pipe as I can then adjust or turn off the water to each area as needed .

I spent most of yesterday and a bit of this morning setting things up in the glasshouse , only to find on opening up the packs that there are two pressure reducers missing . A frantic call to the supply companuy and they tell me there are another two individual packages heading in my direction..

I wish they had marked the packs as pack 1 of 3 , 2 of 3 & , 3 of 3 or mentioned it in their sales info.

Waaaaahh:no: ....I want to play ..... NOW , before we go away for two days sampling the cultural debauchery of a big city & it's night life.

Thank you so much for taking the time to put this together! I bit the bullet and between your post and the one you suggested I check out, I went ahead and bought the pipe and connectors yesterday. My plan to use my poly tubing was abandoned when I realized how much the 4-way connectors cost. Your details at the top for how you cut them helped tremendously.

I noticed on the other thread that he drilled the holes with a 5/64" bit. I think I'm going to try that instead of the sprayers. need to study the video he posted a bit more to determine how many holes.

I was afraid my husband wasn't going to be onboard with spending the money to create these irrigation grids, but he thinks it's a great idea especially since it's so hot and dry here. We're just trying to determine if we're going to go with converting existing sprinkler heads to hook into these boxes, or take the existing, but not used, drip zone we set up and use that.

Thanks again! sunny

Hoggar, you drilled and tapped the holes correct? Or did you just drill and thread straight into the PVC without manually tapping the threads?

Yes I drilled and tapped the holes but I am in the process of revamping
the system and am seriously thinking about trying the drilled hole system
that Plantoid used in his system. It will save a couple bucks on spray heads.

And if I drill them small and at slight angles I might get it to mist as it
sprays. Dr. Frankensteins got nuthin on me. cyclops

I'm very interested in making a watering grid, but need some help. I have two (ports?) pipes from an existing underground sprinkler system that are capped off. They are located right next to two of my boxes, but i'm not sure what I would need to attach a watering grid system to them.

Any advice would be greatly appreciated. Cool

If there threaded you could just make an adapter for a hose connection
then use a short piece of hose to loop over to your watering grid.
If there not threaded you can just mount a PVC hose bib and connect to
that but either way treat it like a sprinkler unit in the winter time and
make sure its well drained.

Don't do it! That's the short answer.

You need to verify what irrigation zones those two heads are on from your controller. The easiest way will be to dig up around the cap, unscrew or more likely cut the cap off, then go turn on each zone for 1 minute to see which one makes the cut off spray like a fountain. Before doing this, have two spare caps to reseal if necessary.

If everything covered by the sprinklers on that zone will be fine with the amount of water you have to use for the raised bed Mel's mix, I'd say go for it, but I doubt it. if it's lawns or shrubs, they'll go soupy and drown or have massive run off.

That's what I did, nothing but problems as the line that was cap was space hold for an additional riser if needed. I just dug it up, cut the end off, attached a new elbow and riser and was ready to go. The only problem, it's tied to the 1st zone of the irrigation system for the back yard. That zone happens to be the plants under the shade of the eaves of the house. The right water amount for in ground house huggers isn't the right amount of water for a raised bed.

If the zoning is right with the sprinkler system, then you just unscrew or more likely, cut the cap off, put a connector on and a riser and go from there. But step one is to verify what irrigation zones those heads are on.

Hoggar, did you glue the pvc joints? I'm just wondering if the parts might hold together and not leak with 25 psi supply and the parts all firmly put together.
