Rated 5 out of 5 by Very easy to use Only took a couple of minutes to dose via filling loop. Far quicker than through bleed valve. 16 Sep 2016
Rated 5 out of 5 by Simple and easy This is a great product, not only do plumbers recomend but you can easily apply via the vent hole in the radiator or via the filling valve on the boiler. Does what it says simple !! Just make sure the applicators are still on when you buy it they easily become detached in transit. 28 Jul 2016
Rated 5 out of 5 by Instant system protection Product is incredibly easy to use, especially with a filling loop. Two minutes and the jobs done. 28 May 2016
Rated 4 out of 5 by Sealed system inhibitor Only recently started using this for sealed system and it's great. A bit pricey though. 16 Jan 2016

Answer: 
Hello Hosh. You can't overdose a system with the F1 Protector, so adding any extra to top up the system will have no adverse effects.
