If you are seeing pools of water or dry patches where previously there was pristine lawn and thriving garden, your irrigation poly pipe fittings may need attention.

Blockages, especially after wet season when ants or sediment can build up in the pipes, are common. It may sound counter intuitive but it is a good idea to flush out your irrigation once every couple of weeks in the wet to keep pipes clear.

The Benefits of Quality Poly Pipe Joiners

If you are putting in a new irrigation system or are upgrading an existing one, the quality of the products you are installing can really effect how long and how strong the system will be. PLASSON fittings are designed to last over 50 years when used according to manufacturer guidelines. There is even research suggesting quality poly pipe systems can last up to 100 years if installed and maintained correctly.

All PLASSON fitting have a unique captive O-ring that helps achieve optimum sealing in all conditions. PLASSON compression fittings also have a longer body which helps prevent blow outs and ensures long-lasting, reliable poly pipe joins.

Choosing The Perfect Poly Pipe

Before fixing or adding on to an system, check whether you have the right pipe size. Generally pipes for residential homes need to be 25mm in diameter. In rural houses, water has further to go, so generally a larger pipe diameter is required.

Poly pipe also has the following colours added to the outside of the pipe as a stripe, to indicate the contents contained within the pipe; blue stripe poly pipe used for potable water, yellow stripe is for natural gas and LPG, lilac or purple stripe poly is used for recycled or non-potable water, cream stripe is used for pressure sewer, red stripe is for fire mains and green stripe is for rainwater and agriculture use.

Marking and engraving of specifications on poly pipe is a mandatory requirement for standard PE pipes and one of the most important and strict requirements. Signs and marks required include the standard mark, the standard number, date of manufactur, machine number and the pipe production line, name of the manufacturer, size of polyethylene pipe, pressure of the polyethylene pipe, type of use and application of the polyethylene pipe in production and type of raw material consumed in the production of the pipe.

Pipes with higher densities, thicker walls and high UV ratings tend to last longer. It’s worth making the investment, particularly when taking the Australian climate into account.

Plasson Quick Coupling Valve for cost-effective irrigation

Irrigation Fittings Designed to Save You Time and Money

PLASSON Quick Coupling Valves, or QCV, have an internal valve that is normally closed so that water does not leak out. To activate the valve, lift up the flipcap and insert the “KEY”. On the top of the key you can insert a sprinkler or a hose.

Installing Quick Coupling Valves can save you time and money. They are quick and easy to install – there is no wiring, programming or power needed. The QCV is permanently attached to the irrigation pipe with a simple push-in key activating water flow. These valves allow you to easily regulate the number of sprinklers in use and to quickly stop and start flow as needed.

Installed beneath the surface, the QCV allows close mowing and similar work and is suitable for mown fields, grazing pastures and other irrigation needs.
