With a Plug&Rain® filter unit, you can significantly increase the reliability and lifespan of your irrigation system. Using a filter is particularly recommended if you use well or cistern water for irrigation. These types of water can be contaminated by particles of different sizes, such as limescale in tap water, sand and coarse particles in well water, or organic matter in cistern water. These particles can vary in size from a few microns to several millimeters. In all cases, it is highly beneficial to trap these particles at a central point in the irrigation system. A filter prevents these particles from entering the irrigation system and clogging nozzles or drip tubes. A filter can be sized in such a way that it only needs to be rinsed a few times a year.
The Plug&Rain® filter unit is reliable and safe. It protects the nozzles and pumps from pollutants and sediments that may enter the irrigation water. The main valve shuts off the water supply when the system is not in operation. Additionally, it stays clean as the dirt is trapped, and the filter can be quickly and easily rinsed when necessary.
The filter unit is installed in the correct position between the water source and the valve distribution. For a filter unit with a main solenoid valve (EXPERT & PREMIUM), connect the solenoid valve cables to your Plug&Rain® irrigation controller using a two-core cable. This ensures that the supply line is always open when an irrigation cycle is active and remains closed outside of irrigation times.
A sieve filter is particularly suitable if you only use slightly polluted water, such as from a rainwater cistern. Sieve filters are especially good at removing organic material like leaves or insects. They are easy to rinse, which minimizes maintenance and ensures that your system runs smoothly.
Disc filters are ideal for filtering sand and fine particles. While they are more effective at removing mineral impurities, they are more difficult to clean because they need to be unscrewed. However, the increased cleaning effort is worthwhile, as filters generally contribute to increasing the longevity of the irrigation system.
Impurities can be easily rinsed out of a screen filter without dismantling it by opening a ball valve in the cover. The particles on the pressure side of the filter are then flushed out by the flow, significantly reducing the filter's pressure drop. A disc filter must be unscrewed for cleaning, with each disc of the filter being rinsed individually.
Depending on the degree of water contamination, the filter should be checked regularly and cleaned or replaced if necessary. However, the filter typically only needs to be changed after some time. If there is a pressure drop of more than 0.1 or 0.2 bar across the filter, it will begin to affect the function of the irrigation system. At that point, the filter should be rinsed; otherwise, there is a risk that, due to the lower pressure in the system, the nozzles will no longer reach their throw distances.
An automatic pressure monitor is useful if you want to ensure that the water pressure in your system remains constant. When the filter is dirty, there will be an increased pressure drop in your irrigation system. The pressure monitor will then sound an alarm, indicating that you should flush the filter. This way, you don't have to remember to check the filter manually on a regular basis, and your system is protected from pressure fluctuations.
The differential pressure monitor measures the pressure difference between the inlet and outlet sides of the filter. If the pressure difference becomes too great, it is a sign that the filter is clogged and needs to be cleaned. This system ensures that you can always service the filter in time before there is a drop in performance.
A water meter gives you an overview of your water consumption and helps to avoid unnecessary water loss. It is particularly important to monitor water consumption when using rainwater or well water in order to plan the supply efficiently. Additionally, a water meter can help detect leaks in the system at an early stage.
With our free planning software, the DVS Irrigation Planner, you can design your garden irrigation in just a few steps. The Plug&Rain® system ensures an efficient water supply for garden irrigation. You can then order the materials needed for installing your irrigation system directly from our online shop.
Easy Installation and Operation of Your Filter Unit
The installation of the Plug&Rain® filter unit is straightforward. Place it between the water source and the valve distribution. If you have a unit with a main solenoid valve, connect it to your irrigation controller. This ensures that the water supply only opens when an irrigation circuit is active, saving water and protecting your system. The filter units are available for wall mounting or as a start box for underfloor installation. During operation, they reliably ensure clean water. Cleaning is quickly done as needed, so that your garden irrigation works smoothly.
Why a Filter is Essential for Your Irrigation System
A filter prevents impurities from entering your irrigation system. Particles such as sand, lime, or organic material can clog nozzles and damage valves. With a Plug&Rain® filter unit, you protect your system and ensure even irrigation. A filter is particularly important for well or cistern water. It catches particles of different sizes and prevents malfunctions. A clean filter also ensures constant water pressure and optimal throw distances of your nozzles.
Filter Cleaning and Maintenance Made Easy
Cleaning your filter is easy. For sieve filters, you can flush out the dirt without dismantling by opening the ball valve in the lid. The particles are rinsed out, and the pressure drop decreases. Disc filters must be unscrewed and the discs rinsed individually. Check the filter regularly, depending on the water contamination. If the pressure drop exceeds 0.1 to 0.2 bar, cleaning is necessary. This ensures that the lower pressure does not affect the function of your system. An optional pressure monitor informs you when cleaning is required. Additionally, a water meter helps you keep track of your consumption and detect leaks early.
Planning and Product Selection with Plug&Rain®
Efficient garden irrigation starts with the right planning. With the DVS Irrigation Planner, you can design your own irrigation. The Plug&Rain® modular system makes it easier to select products, as many modules are pre-assembled. Fewer individual parts – fewer tripping hazards. Choose the right filter unit for your needs: sieve filters are suitable for slightly polluted water, disc filters for sand and fine particles. Both protect your irrigation system from impurities such as sand and organic material. This ensures a long service life and optimal functioning of your system.
