Irrigation Hose

[xerostar]

We are situated in Bo Yang (north Uthai Thani)

We urgently need to buy some irrigation hose.

We've just planted over a hundred different trees, including banana, mango and various palms etc.

Nobody gave a thought as to how to water the trees every day, until they get established.

We have a bore pump and some hose but it it's nowhere long enough and the job takes more then two hours

watering by hand, carrying buckets etc.

I have to get back to work in Oz so I'm afraid nobody is going to do hand-watering every day when I'm gone.

I want to set up an automatic drip-feed system this week.

In Oz you can buy a cheap black PVC hose that's designed for irrigation.

It comes in a variety of sizes and a range of fittings.

I hope it's available here, and if so, I'd like to know the nearest supplier.

.

Thanks for your help!

Global House has branches in most larger towns and carries a good range of poly pipe and associated drippers and micro sprinklers

Hi Xerostar. First time on Thai Visa. Re irrigration hose and fittings..........Excellent supplier on the main road into Bangkok coming from the North. Company called "Super Products" located on the left hand side. Just past the Nava nakon Hospital ( which is on the other side of the Highway. Huge range of equipment for irrigration . They have a web site in english as well as thai

www. superproducts.co .th

Best of luck.

BayBoy, that link didn't work. Issangeorge

That would be because the proper link is without the extra spaces:

http://www.superproducts.co.th/

I can't get the english page to pop up here at work but the thai page is good to go.

Hello All, hopefully Super Products is finally updating the online catalog to the printed 08-09 one. I've used some of their products, and have no real problems with quality. I used the Thanon Phanon Yothin across the street from Elephant Towers in BKK last week for a fitting I couldn't get here in Korat. The Korat Do Home has almost everything as SP in BKK except the 22cm fitting I needed. Do Home's prices are a RCH above what I pay at SP BKK with a 15% discount card.

At the big produce market in Korat, there are stores that sell fitting and drip tapes and other stores in town that sell the same, and mini sprinklers. I think it's just a matter looking around your area, some small shops do have things hidden in corners and under stair cases, take a picture from a website when shopping.

Netafim has some good pressure compensating mini sprinklers if you have long runs or uneven terrain. Netafim cost more than SP. www.netafim.com, I think there is a resailer in KK besides the main store in BKK

Home works & home pro carry a pretty complete line of rain bird & rain drip & have battery timers you can get as well. I put in 3 rai or so of line which is a Godsend as we were doing it by hand & it was getting old & so were we.

Good luck on the drip system.

PS> if you wait till it rains it will be a breeze to lay down the lines.

You dont say what diameter or what pressures/volumes you need to irrigate with - so I'll presume its in the 1000's of litres (per day) and at less than 3-4bar.

Any decent hardware store/ag supply store will be able to supply you with low pressure lay-flat flexible hose in dimaters from 3" to 5". It's usualy blue in colour.

Cost: around Baht 17 - 37 p/meter (depending on pressure rating).

Thanks for all your replies and useful advice.

We went to Uthai Thani on a Sunday and found most shops closed (surprise!)

One hardware shop run by two old ladies had the 22mm black poly hose in 200M rolls.

So we purchased 10 rolls, 300 dribbler heads and two rolls of soft dribbler tubing.

We also got 300 joiners that snap into the poly pipe and connect to the dribbler tubing.

When we got home we found they had sold us the wrong size joiners. It was impossible to fit the

dribbler tubing to them. We tried heating the tube with a cigarette lighter but it simply stretched

and became a loose fit, unable to hold any pressure.

So two days later we went back to Uthai Thani and explained the problem to the ladies.

Only a 160km round trip ..

The ladies displayed no particular interest in our problem - simply suggesting the use of a cigarette lighter - as we had already tried.

They did have the larger size dribbler tubing though! Mazing !

The problem was that this tubing did not match our 300 small dribbler heads (that we had left at home anyway!)

They did not have the correct larger dribbler heads in stock. Would you believe it .?

So we went hunting in other hardware shops and found one that had the dribblers we needed.

So we got those and went back to the first shop and swapped our small dribbler tubing for the larger size.

As it turned out we used all 300 small dribbler heads snapped directly into the poly pipe and used the dribbler

tubing and larger dribbler heads for all the side branches. So it worked out well.

We tried to find an automatic timer and solenoid valves but it was "no have".

It was urgent that we got the system working since we had a dry spell for over a week and all the newly planted trees were getting thirsty.

Buckets and flip flops, with a lot of walking in the heat, over rough ground just don't cut it!

In all we had planted over 300 trees, shrubs, etc. Coconuts, Mangos, Banana plants, ornamentals etc.

I put together a plastic distribution manifold with taps - see photo.

We connected the house pressure pump (1200 Litres/hour) and we were able to water one 200M poly line at a time, each one having about 30 dribbler heads plus about 30 branches with dribbler heads.

When we had finished laying all 8 lines of poly pipe I checked the output of the main bore pump which was 7200 Litres/hour.

So we connected that directly to the manifold and opened all taps.

There was some excess pressure but it worked well. So we were able to do a days watering in less than one hour.

We plan to make a larger bore manifold (40mm) to reduce the restriction and connect another 2 poly pipes (10 in all).

We may also install a timer and a dedicated pump supplied from a tank rather than risk overloading our main bore pump.

Anway, the day after our successful reticulation project was finished, nature decided to show us how it's really done!

We had over an hour of very heavy rain!

Hi Xerostar,

Be carefull of putting excess pressure on a borehole pump, it might deadhead it and burn it out, although it should trip out first, but i have learnt the haed way not to trust thai trip switches.

Perhaps even fit an adjustable pressure relief valve in the pressured piping and saving the excees in a tank in the event of a power cut.

You can buy a timer from Home Pro in Udon Thani,I bought a panosonic timer 18mhts ago, 2300bht, and is fine for the current needed for my 1hp bore pump,

good luck,Lickey.

How much did they charge you for the 22mm poly hose ? Need to buy 10 rolls myself .

[xerostar]

It was 570 Baht per roll (200 Metres)

One major problem we encountered when unwinding the roll:

It's very springy and easily gets tangled and kinked!

Kinks appear to damage the wall of the tube so they should be avoided if possible.

Next time I buy a roll I will make a hose reel that will allow the stuff to be pulled off the roll without coiling up or getting tangled.

It could be used for reeling in the hose again after the job is finished too.

Tip: it's easier to unwind if it's left in the sun for an hour to soften up.

Then when it unrolls it stays more or less straight. When it's cold it's impossible to control.

Here is my design (see diagram):

You would need an empty round 4 gallon drum.

That's about the inside diameter of the roll of hose, as delivered.

You will need a flange at each end to prevent the pipe from wandering off the drum.

I suggest using the lid off a 44 gallon drum (or a round plate of similar size) at each end - .

One flange could be fixed with two or three large screws.

That flange could then be removed to allow each new roll to be placed on the reel.

Then weld in a shaft through the centre and mount on a stand with a crank handle at one end.

With a heavy enough base you could then unroll the 200 Metres without any help and without any of the hassles.

[rice555]

Hello xerostar , I have a question on your supply line size, you say 22mm? Is this LDPE? I have/ use 16, 20, 25, 32 and 63mm LDPE and HDPE, but have not seen 22mm.

I have a 22mm spray tape wich also comes in 31&38mm all in 200M spools. It's like drip tape, but has holes instead of dripper's.

rice555

[xerostar]

It is probably was 20 mm ID. The fittings would be 22mm OD.

The hose is a very tight fit on the fittings and no form of clamp was supplied.

Not sure if it is LDPE or HDPE.

Here is a photo of the fittings that were available:

We tried a couple of the smaller sprinklers shown in the bottom row but they were very inefficient.

More like toys really ..

They leaked a lot of water around the rotor.

They only covered an area of about 3 Metres diameter even at high pressure.

I expect the larger ones on the left would be OK though.

My BIL wants to try irrigating the cassava during the dry season.

That soaker hose would be ideal when irrigating such large areas.

Does it have a rating of say litres/hour at a particular pressure?

Poly tubing is similar to barbed or plain wire in that you unwind it the opposite way to which it was wound , in the case of poly or barb wire just put a stick through the roll and walk the roll along your route letting it unwind as you go.

The coiling up is created by the tension applied when the rolls were made.

A simple way to eliminate a lot of the coiling is to buy a cheap swivel from Global House or where-ever and fix a bit of rope to both sides , one end is anchored at your starting point the other to the loose end of the pipe or wire, the coils come out as you walk the roll.

Hello xerostar, I had to wait till my translator woke up to read the catalog, it doesn't give any info on flow rate, only line pressure to use. From 0.8 to 1.0 Bars.

You can find it on Super Products site by looking at pictures and some English names.

www.superproducts.co.th They have a 2" layflat and valve assembly for the 22mm spray tape or use haddle fittings off PVC or L/HDPE lines to run lateral lines as pictured in the catalog.

1. This is the way I did my 20mm line.

2. Some S-P fittings at at DoHome.

3. This isle and the one beyond the people/carts is just S-P products, it is very well stocked. Well marked. Sorry for the bad pictures, it's a phone!
