Inhibitor application

[Aqua Mechanica]

How do you stick inhibitor into a sealed system that only uses a combi boiler?

Funnel and a fill loop? lol

 

[Jay_1981]

depends, i like using filling loop with concentrated products designed for injection with a calking gun, fernox make this. Failing that I use an injection bottle (you can get them from any plumb centre/HRPC/etc). Some engineers I know believe that injecting in the filling loop the product can go straight into the expansion vessel but i can't see how.

Thanks for that, so apart from filling loop, where else would you inject it? into a rad??

I know you can get combined lockshield and drainoffs.

 

[sonray ltd]

you would put it in the top of the rad not the bottom.

Drop system pressure,isolate radiator furthest from boiler, Remove bleed valve and inject chemical itno rad! replace bleed valve, re-pressurise sysem! jod done....

Nice one, cheers ;-)

I put mine in through a radiator bleed valve.....i was advised to shut the rad off..then inject and close up then open the return to allow it to flow....

I think mine was fernox or summit and the destructions were on the packaging.....

To make it a bit easier a compression elbow will screw into the top of rad where the bleed valve goes, makes it easy to pour in.

I got myself one of those rustbuster bottles. Well worth it if you do a lot.
