Do your own installation

Download our technical sheet here and see here a theoretical scheme.

The installation of a house garden irrigation system can be considered as handcraft, done with no utmost effort, since on one hand the equipment is of simple use and on the other hand the technical information provided by the Plascampo technicians will help you with your doubts. The irrigation accessories are easy to install and there is a series of tools which smooth the progress of installation. In addition, the project of installation and the personalized guidance concerning each situation will clarify the whole process. Thus, the installation may be easily done by yourself. However, if you need counselling throughout the process we can put you in contact with any of our qualified technicians.

- Water flow rate;

In case your water is supplied by your own water pump the technical information on it will allow attaining the water flow rate.
In case the water is supplied by the water company from a tap, either use the water meter to estimate the flow rate or, as an alternative, a rather simple method to do it: get a container with a defined capacity (a bucket would be perfect) and a watch, open the tap totally and control the time it takes to fill the container. This allows us to know the water flow rate. You can give us the records obtained just as they have been read (for example, a 10 litre bucket took 20 seconds to fill).

- Water pressure;

In case your water is supplied by your own water pump, the technical information on it will allow attaining the water pressure.
In case the water is supplied by the water company from a tap, either use a manometer placed on the pipe or question the water supplier’s services about its pressure.

- Illustration of the area for the irrigation system;

The drawing must include the outlines and the measurements, as well as the distance from these areas to the source of the water. It is usually easier to use the original project of the house and the surrounding perimeter. Use our technical sheet for your data.

- Type of plants to be watered

Describe the type of planting in each irrigation area, for example a lawn, rock garden, herbaceous plants, trees, hedge, mixed types, etc.

- Uneven ground

In case you have significant differences in level, mark them in the illustration and describe the dimension.

Low pressure in irrigation pipes


- Perforated hose


If the breach is small (less than 20 mm) in a tube with a nominal diameter of 32 mm you can use a Clamp Saddle with the same size as the tube, place it with the exit over the breach and cover the exit of the Clamp Saddle with a buffer screw.
If there is a cut on the hose and you cannot use the solution presented previously, you cut off the damaged area so that both extremities acquire a plain, smooth cut and perpendicular to the axis of the tube and use a quick fit joiner with the same size as the tube. This way the length of the part of the tube removed is compensated by the joiner. 
In case the damage on the tube is longer than the length of the joiner, you must add a new section of tube. In order to do that, you cut the damaged part of the tube so that both extremities acquire a plain, smooth cut and perpendicular to the axis of the tube. You measure the space between them and cut a new section of tube with the same dimension. Be careful to take into account the length of both quick fit joiners with which you will join both extremities. 

To cut the tube you can use a proper scissors for cutting tubes. 

To tighten the quick fit parts you can use a proper spanner for that specific purpose.

- Dirty filter

The filter is an essential element of any irrigation system. It is installed in the beginning and its function is to retain all sediments floating on the water which would, otherwise, clog the pipes, sprinklers and drippers. 
This way the filtering elements (screen or disc cartridge) of the filter start to obstruct after a time and that causes the reduction of the water flow at the filter exit. Therefore, it is fundamental to clean the filter regularly, dismounting and washing it with clean flowing water and also using a brush. 
A way to avoid filter clogging is by keeping a regular preventing maintenance. For that you should place a manometer at the start and another at the end on the pre-installation spots on the filter. Once the pressure at the start and at the end is practically the same, the filter is clean. When the exiting pressure is lower than the pressure at the start in about 0.75 bar (the equivalent to 0.75 kg/cm2) the filter must be cleaned. Without the help from the manometers you should count on your experience to foresee the right time to clean the filter.

- Obstructed irrigation diffusers (sprayers, sprinklers, micro-sprinklers, drippers)

If one of the diffusers has decreased its irrigation performance on a determined spot, not having the normal length of spraying, having irregular water spraying or even not spraying at all, you must dismount the removable parts to proceed to their cleaning or replacement whether in sprayers, sprinklers or drippers. You may have to dismount the tube in order to clean the dirt that mounted in it from the start.

Preventing and cleaning the limestone

Calcareous waters originate enormous problems in clogging the irrigation installations, much for its accumulation on the internal wall of tubes as well as in valves, sprinklers, sprayers and drippers. 

To prevent this situation you can periodically insert a small percentage of nitric acid in the irrigation system in order to dissolve the forming little clogs. 
If the irrigation system already has large limestone formations you will have to insert a higher percentage of nitric acid in the irrigation system. The acid may be poured into the irrigation pipe by means of an automatic dosing/fertilizer (EZ flow system) or using a ventury system with a flow regulator. Either system should be installed in a by-pass system at the beginning of the irrigation installation. 

The treatment must be made after the irrigation so that the water with the percentage of acid fills the pipes and accessories. To quantify how much acid you should use you must take into account the quantity of water that fills the tubing, calculating its volume. Based on that volume you calculate the quantity of acid you need. Using nitric acid, the most commonly used in these situations, the percentage of acid comparatively to the total water volume should be of 2,5% to protect the system and up to 4% to remove the existing limestone.
