I did extensive 'research' on this over the last few months, hozelock make nice systems but they are limited and expensive. Far easier to make your own to exactly the specification you require.

this to attatch to outside tap (if you plan on running several lines

13mm irrigation hose

then one of these kits (can be picked up in wilko or cheapo shops for a few quid normally.

then u need a basic watering computer, the simple ones are about 30 quid.

here's a vid of how to set it up

You can add all sorts of different types of drippers, depending on what style of watering you want to achieve.

Yes expensive if you buy from B&Q, but you can source lots of this stuff cheaper around the net. You also will be able to tailor the system precisely to your needs. If you look at professional systems, you will notice they tend to always use 13mm hose rather than 4 mm. This is because the 4mm can block much easier, if you use the 13mm as the 'feeder' pipe then individual 4mm piping, you have better control and also if there is a blockage, it's only on one dripper. The 13 mm pipe can also be used directly on beds with drippers inserted straight into the 13mm pipe.

Hope that gives you some food for thought.



Brummiben ,unfortunately my auto basket watering system only extends to half an inverted water bottle connected down through the soil into a small tub with thin cut off toweling in the soil acting as wicks and it works, haven't got a patent for it yet but might right off to The Dragons or maybe not ,seriously iv not seen a good one at a reasonable price yet but I'm following your thread so good luck matey

Last year I tried to set up a system but using all thin tube. I found that water didn't get through to all plants. Would I be better changing to 13mm tube?

What is the maximum number of drippers that could be run off one pipe?

Thank you for your detailed info on this.


use the 13mm tube as your supply, it's the beauty of drip irrigation, you need no water pressure, well hardly any! In answer to your question Bev, it's going to be trial and error. Your mains pressure is unique to you, so you need to experiment to find what drips at the right rate. Then it's just a question of sticking the watering computer on before!


Well the 4mm pipe and dripper kits are very easy and cheap to get hold of, certainly not £20, and they are pretty much all the same quality, ie cheap. I personally would be using the 13mm as a supply and then run the 4mm off the supply line. You can just put holes or attach drippers on the 13mm line, but this is better for using in beds and borders. If you wish to water baskets, troughs and pots, using the supply pipe with 4mm offshoots is the better way. Also gives you a great deal of flexibility. I'm hoping that once my system is sorted, I'll only be doing feeding watering once a week. Last year even though it was raining, it was still taking me maybe an hour and a half to water all my pots etc every day.

Thank you, BrummieBen, I have never before understood how to do this. I'm going to set up a system within the next couple of weeks, ready for our first week away in the caravan!

I bought a container watering kit from its currently on sale. the kit had all i needed to water my patio pots. I found it easy to install and adaptable, as i change my pot layout every year. They have all the extra bits and i found them cheaper than Hozeloc. 


Hey. I took a look at the YouTube video mentioned. Its not that detailed, but at least it gets to the point. Might be worth having a look at the Easy Garden Irrigation YouTube channel. Loads of detailed videos about all the different parts available for drip irrigation systems. It's probably worth mentioning that most irrigation manufacturers (including Hozelock) stick to the same sizes, so you can mix and match to get the best price. Just avoid Gardena. They went off and did their own sizes, so dont work with any others.

a related question. i'd like to set up a irrigation system for our garden. i had assumed it would be simple and easily fixed with an old fashioned sprinkler. the kind we used to run through as kids. and that works for almost the whole garden. doesn't seem to cover quite the ends, but we'd probably be willing to sacrifice that.

the real complication comes from the 2 pear trees we've planted in big pots behind the shed. there's no way the sprinkler is reaching that far, and if it did, it would never spray over the shadow created by the shed.

so i'm on to thinking about the 4mm drip feed sprinklers. the question then is, would it be better to set them up on a completely different line? or to branch the line right before the sprinkler with a y valve and then set them up?

i'd like to have all this set up on a timer too, especially for when we go away. if it was a completely separate line, that would need an additional timer etc.

the worry being that if it was branched just before the sprinkler, would that take away noticeable water pressure?
