yes, mine came with the compression fittings to go onto a (vertical) 22mm copper pipe
however, when I first got it, I did not have a pipe I could get at to put it in-line (28mm old boiler pipes went into ceiling, and emerge in the airing cupboard, packed tight together with the pump, 3-port etc. I am sure it is easy to fit one on a new installation where you plan it in to place before running the pipes, or if you are used to changing pipe layouts. I am just a householder.
I did not think of that before I bought it; when I previously fitted a Magnaclean in a different house, there was plenty of room round the boiler, and the "elbow" valves meant I did not need to have play in the pipes to squeeze it in.
Easy when you know how, I expect.
