The cheapskate who installed out CH didnt fit either, just a gate valve
cracked open a bit, which gets a bit noisy as the TRVs throttle back. Im
about to fit a new pump and now seems like a good time to sort this.

Any pros and cons to any particular valves? Any recommended magnetic
filters that dont cost an arm and a leg and are easy to fit?
