Hi, I have a slow drip from where the water pipe goes in at the bottom of my radiator. I guess I need to buy a new connection but I don't know what is is called so I cant search for it online. Can someone please take a look at the pic and tell me what to search for? It is the chrome elbow thing. The pipe going in is a 10mm speedfit pipe so I assumed the elbow is speedfit but I looked on the speedfit site but cant find anything similar. At the other end where it screws on to the bottom of the TRV, the outside diameter of the connector is about 24mm. Thanks
