Rattling radiators
Discussion
A tenant of mine has a problem with rattling radiators. Its happening every 10-15 minutes and sounds like ball bearings rattling through the pipes. It's especially noticeable an night.
Its a 60's built place but with a relatively new condensing combi boiler and TRV's on all but one rad. They are Drayton TRV4's so decent bidirectional units.
A plumbing company have been out to look at it and a few other issues, but they seem completely useless. They just report that it's not happening while they are there, even though the tenant has shown them a video of it happening.
Any ideas? The Internet says it could be TRV's rattling, but I have about 12 Draytons in my own home and not a single rattle.
