The previous reviewers have pretty with its 5 Star Rating

The cold-water meter of contactor (!) - German brand quality - you can eg as garden counter only recommend. Also included are seals and - if needed - the seal wire. My installer has the part fitted tightly in 10 minutes for 10 euros (so far I have the homemade). It is important to determine in advance the length (there are usually counter with 130 mm length, but often also with 110 mm, more rarely, other length measurements). Important also the value DN 20 (available on the (old) meter and describes the flow capacity of 2.5 cubic meters per hour) and also the attention of the external thread (3/4 inch inside with 33 mm outer diameter). To note also the optimal (!) Calibration period, currently (early 2015) to 2021 incl. (Ie 6 to 7 years). Delivery by ew building services model within 2 days. Unrestricted recommendation.
