As for the service, it might have been useful to make express mention in the manual, how much water the little machine, if you connect all hoses, consumed per day. But if you have it to yourself zusammenrechnen and happens when the pump is in operation once a day, to 1.28 liters. For a longer holiday so come as quickly something together, and the 9-liter trough from the alternative version with reservoir then reaches a maximum of one week. Quite nice and stable transparent plastic tubs with lids that can hold a lot more water, I found, for example. at Ikea. It is important that they are "transparent", because if one the little machine decreases the watering flowers, you unfortunately forgets quickly, in time again to refill water, and "with lid" because the water otherwise, especially, evaporates quickly in the summer and dirty / or dust, leaves etc..
Since the pump is a pronounced lightweight, it unfortunately has a tendency to be drawn from the possibly air-filled main hoses up - so it rests always pretty neatly at the bottom of the water tank and is not idling, they should be therefore as far as possible complain with something eg. etc. with a small plastic bag full of pebbles, which is attached with adhesive tape to the pump and then sunk with her.
It is also important that the pump always deeper than said to be watered flower pots - otherwise there (even if no power is connected!) Through the "siphon" inevitable flooding, unfortunately trickled so that they are only after some time , at worst, after returning from vacation, noticed. After you've built everything, you should therefore always check again in peace, whether at currentless pump really anywhere water is coming from myself and put the pots in question possibly slightly higher.
Not at first sight is understandable, as I gather from some of the reviews, even the logic of integrated in the supply transformer timer: Once you put the plug in the socket, it supplies the pump for exactly 1 minute with power, "remembers" the time and then does the same time every 24 hours. Pulling the plug out (or falls from the current), everything is forgotten, and the game begins again. Will you not therefore be repeatedly awakened middle of the night by the purr of the pump, you should therefore plug the transformers as possible to a time in the outlet to which a non-annoying pump noise.
If a once daily watering enough, you do not need any additional time switch, with repeated casting by means of a switch on the other hand one has to take into account the then increased water consumption and purchase a correspondingly larger reservoir.
After my plant population has now increased considerably, I allowed a second holiday watering me recently - both the old 1995 and the new do diligently their service, and I have these purchases today regretted a moment.
