Towel rads are on the whole poor quality IMHO.
Bang out all the scale/rust/sand and flush it through thorougly before you fit it.
Getting the threads to seal can be difficult as there are normally only a few threads in the rail.
Use PTFE tape wound in a slight taper to seal threads or use tails fitted with O rings type seals
Avoid overtightening - easy to strip threads.
If you can pressure test with hose before fitting.
Solder 15mm copper tails onto the 10mm and use 15 radiator valves.
10mm valves can be poor quality and it may be harder to find them in chrome.
Avoid using reducing sets to convert from 10 to 15mm - they often leak.
