Glow worn boiler Filling Loop

No there is no cap on the filling loop.

Not sure what model of glow worm boiler you have,but normally the filling loops don’t have caps. In the water bylaws it is recommended that filling loops be removed/capped where possible due to possible contamination of mains water, which in this case could have been done. Hope this is helpful

If you can confirm the glow worm Model please as a lot of them have a built in loop as not caps ,unless it’s a standard filling loop and it can have caps Thank you

Hi sorry all depending what model but most dont thanks
