The reason I went to NABIC was because we have to meet certain water regulations. After a chat with Northumbrian Water, they suggested looking into NABIC products as they are WRAS approved and suitable to use on all potable water applications.
I went direct and bought 4 pipe interrupters with next day delivery, which have been installed in our on-site laboratory. My user experience was great and I liked the fact that site has all the necessary specifications and prices easily to hand.
