We have a HWW installed in our house for the promotion of well water and forwarding in the garden. Our old HWW was presumably the. almost identical device from !!! 1998 !!! and has at the end of last summer (2012) by entering Macken (pressure loss, in the end no longer pump start-up) has finally given up the ghost. A review has still shown that a complete exchange would undoubtedly be thoughtful. To avoid the conversion of incoming and outgoing lines, we ordered the identical unit to a total of 15 years of operation again. The installation therefore proved quite simple and fast. The only annoyance is the supplied connector between pump and filter plastic turned out. Despite the supplied sealing tape did not succeed this Verbinung reasonable and above all to get close. It was replaced by a metal fitting from the hardware store and worked from then to date properly.
The switch-off of the HWW is preset at 3 bar and the cut at 2 bar. For our conditions (supply garden, pond, pool, etc.) absolutely enough.
Because it mentioned offense the product from me only gets 4 stars, with a metal compound only cost 2-3 euros.
