Now that we have a fully working and not leaking GlowWorm 30cxi, I can start to look at some of the plumbing/heating work I have on my to-do list for our new house so have a few general questions...
Due to the on-going leak and constant topping up, the system is very dilute in terms of inhibitor although from initial inspection appears relatively sludge free, with no cold spots on any of the rads. I plan to run some system restorer through it for a couple of weeks then flush and refill with inhibitor and possibly noise silencer. The MI suggest either Sentinel or Fernox products - I propose to use X400 to clean, then re-fill with X100 and X200.
Anyone see any issues with that, with the stainless HEX in the 30cxi, or any other considerations I should be aware of?
Obviously I'll need to drain the system at least once to do this - as far as I can tell the main drain points are from radiator valve drains. I'd prefer to fit a central one, below the return to the boiler in our kitchen (lowest point of the system) for easier access & draining. This is 22mm pipework but I can't find 22mm drain valves after an initial Google.
Is it just easier to reduce to 15mm and use a normal 15mm drain valve or am I just not searching hard enough?!
Finally, the BG engineer who fixed the PRV/EV leak yesterday showed me a SpiroTrap MB2 and suggested we have one fitted. At ~£250 from BG it was a bit steep, and follow-up research shows I can get one for about £80 and fit it myself. I'd probably go for the MB3 actually.
Are these any good or is the Fernox TF1 better? (I've ruled the Magnaclean out after reading lots of leaking complaints on here.)
Should I fit the filter before I add the X400, with the aim it will help pick up and capture any sludge that is worked loose?
I need to swap/remove a few TRV's but can do this at the same time as draining the system for the above works. I intend to fit a wireless stat to the system at some point soon but will save that for a follow up post once all of the above is complete...
Any other suggestions on preventative maintenance appreciated!
