Pipe’s in irrigation
Civilizations have been using various methods of irrigation to supply themselves and their crops with water for a long time the Romans, Egyptians, Aztecs just to mention a few early societies. In today’s irrigation world as far as the domestic situation around the Perth metro area is concerned there is two clear types of pipe that make headway I the consumers mentality these are the Polly pipe and the pvc pipe both of them have their pros and cons which I will discuss.
The pvc pipe has been on the scene on a domestic level since the seventies and there is a lot of older house’s in the Perth metro area that have only pvc pipe for their irrigation. The pvc pipe is very ridged ad not very flexible there is however a lot of fittings available that are often used. The tee’s, elbows, forty five degree elbows, all of these fitting’s come I a variety of sizes just as the pvc comes In different sizes as well for example there is the 20mill, 25mill, 32mill, 40mill, 50 mill, etc. Also with these different sizes their also different thicknesses of pvc as well from class nine, class 12, class 18, class 24. These different class numbers represent different grades of thickness the higher the number the thicker the pvc. Most of the time all the individual in a domestic situation will require the standard class nine pvc which can be acquired from all reticulation outlets. One of the problems that a lot of people have with pvc is when there is a break in the pipe with two fixed ends and there is no flexibility in the pvc. The reason that fixing such a break as mentioned is because the pvc fitting that the individual purchases for the task of amending the situation has to intrude upon the pvc pipe. This is not an issue on the first joiner that is glued onto the pvc but when it comes to the second joiner the individual then has a problem due to the lack of flexibility in the pvc in that the second joiner will simply no go onto the new piece of pvc that is being used to amend the bread and the old pvc. The most common way for the individual to address this issue is to use the fitting known as the slip fix this is a fitting that is extendable. The main advantage of this is that the fitting will be able to join onto the pvc at one side of the break and then extend onto the other side of the break. This both sides of the fitting to encompass the pvc as is desired and the situation is then amended. Pvc pipe is most commonly used in the lawn areas of the house. There is a special tool called a pipe cutter that is great for cutting pvc and polly pipe as well
Polly pipe is a pipe that is more flexible and very durable and has been around for the past couple of decades. Polly is often found in peoples gardens it is easier to maneuver and it can be adapted to easier than its counterpart. Like the pvc there is also tees, elbows, joiners as well. the polly pipe is easy to repair if there is a break in the polly pipe because of its flexibility one does not need to use any specialized repair fittings the individual can simply unearth the polly pipe install a joiner either side of the break join the new polly to the new joiners. This is easy do even though the polly joiners will take 20mill of the polly pipe when the joiner is installed into the polly pipe. The reason that it is easier than the pvc is simply because of the flexible nature of the polly pipe. Polly pipe also comes in different grades just like the pvc but in the domestic situation there only the low density polly pipe. There is also three different sizes that are commonly found in the domestic houses in Perth, these three size are 13mill, 19mill, 25mill and fittings for all of these three sizes can be found at all good reticulation outlets. Unlike pvc polly pipe is not glued together and there is clips that are specifically made for each size of polly pipe that the individual uses a pair of multi grips to tighten. The downsides of polly pipe are that is easier to break with a shovel under pressure will not perform as well as pvc but still a great choice for the garden.
