For me, this installation has only one minus - this is when you need to get into the insides, then you need to unscrew a couple of bolts, but this is not critical and you will certainly climb there even probably more than once a year. The water is started with a flat screwdriver, and in a more expensive model there is already a valve there. Otherwise, a good installation, no worse and no better than competitors. But the company itself is definitely worth attention, everything works like clockwork for them, and if you have cleaning filters at the entrance to your system, neither rust nor small pebbles will get into the installation itself, which will make the work of this thing truly remarkable for many years.
