Sealed system inhibitor injecting and new sink Q's

[JimDowson]

I have 2 questions, if anyone could offer me some advice it's be great:

1) I have to re-fill my heating system, and want to add corrosion inhibitor. The system is SEALED though, so I have to inject it via the radiator vent I believe? The problem being, my radiator vents are the in-built type, and not the ones that can be removed using an adjustable. Is there anyway I can inject inhibitor into my system to protect it?


2) I am replacing our kitchen sink at the weekend as it has a crack in it It is plastic. I am thinking of buying a stainless steel type sink. The taps, somehow, come through the worktop and are not connected to the sink directly. My questions are:

Are plastic sinks easy to remove? I can't see how they are connected / inset into the workbench, there doesn't seem to be any clips!

Can I get a taphole less stainless steel sink??!

I believe sinks come with sealant strips that protect the worktop where it sits on, and also I should use silicone sealant around the inside edge of the worktop, which will be hidden, but to stop any water over time rotting it?? Is this right??


Last point: Do sink waste fixing kits come with decent sinks? The bit I am thinking of, is the short waste pipe/connections between the middle and main bowl drainers?

Thanks for your advice and guidance.

Sorry for replying to my own post! Can I inject via these type of rads?

get fernox express and inject via the filling loop.

 

[JimDowson]

the boiler has no filling loop, it has a plastic key!...

Isolate the smallest rad via the valves and drain rad. remove rad and inject inhibitor, replace rad and open valves. Now top up pressure and run heating for a while to circulate.

 

[JimDowson]

thanks i will do that

do i inject into the rad itself??

You will possibly find the sink is stuck down with silicone so a blade run under the lip should free it.
Yes most sinks come with inserts for tap holes so you can use them either side or just blank both off.
