A friend of mine is on his third heat exchanger on a Sabre combie. Volkara has advised him to install a pressure reducing valve and a pressure vessel on his cold water main. What is the correct order to install these components? ie. Stop cock - pressure vessel - pressure reducing valve. His mains pressure is at 3.5 bar, What pressure should he set the PRV to and pressure vessel charge.
Thankyou.
Thankyou.
