I'm looking at changing some of the soldered 22mm flow/return copper pipe at the boiler with compression fitted copper pipe. This is to (1) move the existing magnaclean micro down as the lid cannot be removed without twisting the pipework, (2) remove the near head-stripped drain valve, (3) to add another magnaclean on the 22mm flow and (4) add a drain valve (22mm x 22mm x 15mm compression tee + 15mm compression drain valve) to both flow and return.

I will use plenty of 22mm snap fittings when using copper compression fittings And can a magnaclean be used around 40cm of the boiler? The magnaclean website does not state a minimum distance from the boiler . Can I have advice please, thanks I don't know how to solder and I definitly wouldn't feel comfortable trying to solder so close to the boiler even if I did
I think yes to all your questions but I'm not a plumber so this will bump your post. My answer is based on my own boiler that has compression fittings
Ideally the Magnaclean wants to stay on the return as it picks up all the **** from the system before it goes through the boiler. Compression can be used close to the boiler no problem.
The water circulates forever (obviously) so it really doesn't matter where or how many. An inline strainer may however be worthy addition. If the system water is bad currently then address than via Fernox F3 then rinsing thoroughly, rather than adding more filters.
it matters, they should be on the return so that the debris doesn’t get into the thin waterways in the heat exchanger?
If the OP doesn't feel the micro is up to the job I suggest he just upgrades it to the Pro model and not bother fitting a second. Does the micro get clogged up?
A magnaclean on the flow does prevent sludge from the boiler impellers and heat exchanger (which do corrode) from getting into the rads. The magnaclean on the return stops sludge from the rads getting into the boiler. The return one is the main but there's no harm having a magnaclean (as I already have 2 why not use them both up at no extra cost) on the flow and return
Seems simple enough. Why is this strainer not an essential add on? Probably extends the boiler's life by a good few years. Is this fitted on the flow or return, and how far from the boiler?
But the filters are far from 100% effective with what is flowing through them, just having the filter anywhere in the system will steadily clear deposits from the water over time.
Fit on return before the boiler. It just prevents flakes of crud getting into the heat exchanger really. Fit one on the cold supply to the boiler as well if you like, for properties with iron mains water supply it will catch some grit over time.
Do these Y strainers get clogged with boiler leak sealers? I'm using the Sentinel leak sealer (https://www.toolstation.com/sentine...=3p.ds&gclid=4f4a74c2dea01dcaf91a1552e7cd989c).
Here's a pic of the finished pipe change: https://e.pcloud.link/publink/show?code=XZ4bfJZu2Hc4jI7ixLc6bj4TUMybLH9FRAX. It shows the fittings in place. All works - no leaks. Plenty of pipe clips. There is a filter (https://www.toolstation.com/compression-inline-y-filter/p16650) just above the magnaclean on the 22mm return pipe
