I have a Spiro filter, one of the older type, solid brass, no magnet, with a labyrinth to trap particles and a valve underneath to squirt it out.
It was briefly fitted when I had a powerflush and new boiler, but the installer removed it when he wrongly thought it was obstructing flow (in fact, his unqualified assistant had installed the pump wrong).
The system is an open-vented Vitodens 100 Compact showing no signs of dirt or corrosion, and I want to keep it that way. It has Sentinel X100. The return pipe on the boiler already has fittings to take it, but the gap has been filled in with a bit of pipe, so it would go back easily.
Is a modern filter with magnet sufficiently better to make it worth binning the Spiro and splashing out on a new one?
