Hi all,

I've got the above pump. I took the head off to clean out the crap in the impeller and put it back together again, I've had sentinel x400 running for almost a month now. My 11 rads dont heat up when all are turned on, but if i isolate downstairs then they work, same for if upstairs is isolated. Is the pump knackered? It sounds like its doing the business but maybe it doesnt have the oomph any more.

Any recommendations on a cheap alternative? or something i could do to get this thing going? Cheers in advance

Have you balanced the system?
Yes all balanced as far as I'm aware. Ive tightened the lockshields up as much as poss upstairs. Does it matter that at the end of the line downstairs is the biggest rad in the house? Cheers

This seems affordable, what's your experience like with them? Can't find much online. Cheers
