Rated 5 out of 5 by Excellent replacement I have bought RMaquastel stainless steel as replacement for copper cylinders a few times and so far no problems or callback. The bonus is the ease to install as all the connections are 22mm compression fittings, Excellent product at good price so I will continue to buy them in the future. 29 Jun 2015
