Monoflo question

geno54

Have a convector on a mono-flo system that is going to be removed and not replaced. Second convector in the room is plenty. Question is, is it better to cut and cap that branch or connect it

Either connect/bypass...

...or cut out the monoflo fitting from the main. Otherwise you'll increase pressure loss and reduce flow through the whole system.



Simply replacing the emitter with a bypass pipe gives you the closest thing to a guarantee that you won't affect anything else - but now you also have water in pipes going through a wall where people wouldn't expect to find it. This could be a source of confusion and confusion-related unfortunate incidents in the future.



Cutting out the fitting from the main is neater but harder to do. It could also cause issues if there are two branch circuits that are "staggered", as could be the case if you have emitters below the main. There are many possibilities, so a crude drawing of the system with the placement of the monoflo fittings would help.

Forgot the disclaimer...

...not a pro, more like a proud owner of a monoflo system with convectors. At least until this Spring.

Not a pro either but,

I vote for cutting out the monflow fittings completely and replacing with regular couplings. The amount of work should be about the same for either case since you are going to have to drain the water out either way. Of course there could always be complications as mentioned in the previous post

Unless

you don't have access to the main branch for some reason. If thats the case connecting with a straight run is your only option, capping off should be avoided.

Thanks guys. Difficult to get to downstairs, so I'll connect it
