Expert Answer

Hello, Eugene.

Immediately, we note that if a non-return valve is built into the device for accounting for cold or hot water, then no one can force you to additionally install another device - you are formally 100% right. And even in the event of an aggravation of the controversial situation, you can resort to the help of specialists of the manufacturer.

Nevertheless, we recommend that you listen to the requirements of the installers and buy a non-return valve, made in a separate housing. As practice shows, the devices combined in one case do not differ in high quality and reliability. As for the separate valves, you can choose a good, durable product and forever forget about the problems associated with the reverse movement of water. By the way, devices manufactured in Italy or Germany are considered the best. Budget cost and good quality stand out devices of Turkish and Russian production. As for the products from the Middle Kingdom, sometimes among the Chinese check valves there are also worthy brass specimens. But only a specialist can distinguish them from cheap things.
