Hello, over winter I replaced two seacocks on my recently purchased and well looked after B32, both original 2004 standard steel/ brass units, one being the large awkward to reach sewage valve. I replaced with bronze units from SBV. Although both corroded so much that nuts could not be moved, I used an external angle grinder ( excellent tuition on you tube) very easy to do, both removed in under 30 minutes, a quick clean around the grp hole then in with the bronze skin fitting and cock, nuts tightened and locked with Loctite. An amazingly easy job, giving huge peace of mind. Both skin fittings looked good, yet when cut with grinder both completely pink with dezincifcation and one crumbled in hand!
