FAQ
What is the difference between Tropf-Blumat and time-controlled systems?
In time-controlled systems, a computer controls the water discharge and a preset amount of water is always dispensed at a certain time. Neither the special features of the plant’s location (exposure to sunlight, current level of soil moisture) nor how much water each individual plant needs are taken into account. Tropf-Blumat only reacts to the soil’s moisture level.
Should I turn off the tap when it rains?
No, always leave the water supply on. If the rain supplies your plant with sufficient water, then Tropf-Blumat will not dispense any water.
What happens if there is an interruption to the water supply?
To start with, nothing will happen. However, if the water supply is cut off for any length of time, the roots could draw all the water out of the sensor. Then air would enter the system and the valve would no longer open. In this case, refill the Tropf-Blumat.
Is Tropf-Blumat suitable for watering the lawn?
No, Tropf-Blumat is only designed for localised drip irrigation. You need a watering system designed to cover a large area for your lawn (sprinkler, rain guns etc.).
No water is coming out of my new Tropf-Blumat even when I have completely unscrewed the screw.
The Tropf-Blumat is delivered closed. If it has been kept on the shelf for a long time, the drip tube may have stick together near the adjustment screw. Pull the tube out and massage the gummed up section for a while.
After cold nights in autumn, the dripping only stops very slowly.
When temperatures drop by 5 degrees, the membrane of the Tropf-Blumat becomes harder and consequently does not shut off as quickly. Close the adjustment screw down by 2-3 marking arrows.
Why do I have to use a Pressure Reducer?
The Tropf-Blumat system is designed for a water pressure of 1.3 bars at the most. If the pressure is higher, there is a risk the tubes may come adrift from the connectors.
How tightly should I screw on the Pressure Reducer?
Screw the pressure reducer on well by hand. Do not use a plumber’s wrench or another tool under any circumstances as this might damage the thread.
What happens when the connection between the tap and the Pressure Reducer is no longer watertight?
This usually means the rubber seal of the dirt filter has become brittle. Replace the sealing filter with a new one, it is available as an original accessory. However, any suitable sealing filter from a bathroom retailer can be used. Do not use force or a tool to unscrew the Pressure Reducer further under any circumstances otherwise you will damage the plastic thread. Also check whether the contact area for the sealing filter on your tap is corroding, covered in limescale or scratched.
Should the Pressure Reducer be connected in a certain position?
No, the Pressure Reducer can be connected in any position, the 8 mm outflow can also either be directed upwards or sideways.
How big should my tank be?
That depends on the number of plants and their water needs and how long you do not wish to top up the tank.
What material should my tank be made of?
It doesn’t matter what it is made of. It is best to use an opaque tank to prevent the growth of algae. Place a lid on the tank to prevent leaves or insects from getting into the water.
Where is the best place to put the Tank Connector?
It is best to attach the Tank Connector a few cm above the base of the tank. Then suspended particles can settle without getting into the tubes. If you have a large tank, it is best to set up a larger and sealable outlet at the lowest point so that you can easily flush out the tank when required.
Why may the tank only be 12 metres higher than the plants?
The Blumat system is designed for a water pressure of 1.3 bars at the most. If the pressure is higher, there is a risk the tubes may come adrift from the connectors. For every metre of height, the pressure rises by 0.1 bar. If your tank is 12 metres above the plants and if the water in the tank is 1 metre high, the pressure for your plants will be 1.3 bars.
What should I bear in mind when laying out the tubes?
Lay the tubes so that they do not constitute an obstacle. Make sure that the tubes are not kinked. Don’t pull them too taut as they will contract somewhat in winter.
Why can’t you use any lubricants to assemble the Feeding Tube?
These substances corrode the tube and make it brittle. To make assembly easier, you can wet the tube or warm it slightly with a hairdryer.
Can I regulate the water discharge of a Distribution Dripper?
The black screw should not be adjusted. This ensures all Distribution Drippers react the same way. If a Distribution Dripper is visibly dispensing less water, you should clean it.
How do I clean the Distribution Drippers?
Unscrew the screw completely and lay both parts in lukewarm water, add some vinegar or descaling agent. Also remove incrustations on the screw with an old toothbrush.
My Distribution Drippers regularly become blocked with limescale, what can I do about it?
If you have hard water, a build-up of limescale cannot be prevented. You will simply need to clean the Distribution Drippers more frequently.
