The part replaced with us a small Y-distribution and walks on two Gardena Oscillating Sprinkler 350 (2 + T). The other terminals are not at the same time in operation. Opposite the old Y the pressure is noticeably better. But I must also say that we have our own 3/4 inch line at a 12.000, - Euro expensive booster station (high-rise) is connected and supplies in output around 5.5 bar. This could hardly be a pressure drop observed in spite of two open lines. Through both Regner together about 2.5 square meters of water are scattered from us per hour. But space should be available, the part is really not bad at all, but an architectural monster. Of course you can it, like all plastic objects, can not be outside in winter, but that should be obvious and is also somewhere on the box each well.
