No Nonsense Central Heating Inhibitor Concentrate 310ml is rated 3.3 out of 5 by 30.
Rated 3 out of 5 by from Good product, poor cartridge Product seems to work fine, issue is that if there is any residual pressure in the system then you get water and inhibitor coming back past the cartridge plunger.

Rated 3 out of 5 by from DISSAPOINTING DUE TO LEAKAGE I bought this product after a quick scan of recent reviews praised the installation via filling loop facility. I fully depressurised the system as per instructions and used the adaptor supplied for the filling loop, however, upon injecting the liquid, I found about a third of the contents leaked out of the rear of the cartridge on to the customers floor, who happened to be watching and was not too pleased! Upon reading the reviews again more thoroughly, I now see others have had similar experiences. It would appear the standard cartridge normally intended for thick mastic etc. is unsuitable to dispense a thin runny liquid such as this, as it just leaks out past the plunger with the slightest excertion, therefore is not fit for purpose. I was dissapointed with this product. In future, I will just do it the old way, i.e. just disconnect a rad tail and pour it in!

Rated 1 out of 5 by from Poor product There is a fundamental problem with this product that has been reported many times before. The contents leak back past the cartridge seal when injecting the inhibitor even when under low pressure. This product is not fit for purpose. The cartridge is designed for thick sealants, not thin viscous liquids. Would not use again.

Rated 1 out of 5 by from Poor Quality Cartridge A lot cheaper than branded inhibitor but the cartridge is poor quality. I followed the instructions to the letter but the liquid leaked from the back of the plunger when adding to the system leaving a right mess!

Rated 5 out of 5 by from Really simple Not much of a DIYer but this was really easy, fitted a new radiator and I'd forgotten to re add some inhibitor so this product was ideal, drained the system of a few litres then unscrewed the bleed valve in the top radiator (bathroom in my house) screwed the adaptor in and simply pumped in.

Rated 5 out of 5 by from Easy-peasy No Nonesense by No Nonesense by nature. Simply depressurise primary circuit, disconnect filling loop from mains supply, load cartridge, screw connector to inlet pipework via check valve and pump. Once cartridge discharge, disconnect and discard cartridge, reconnect filling loop, repressurise promary circuit - job done. No mess, no draining, no headache and the price is good - simples!

Rated 4 out of 5 by from Easy to use product Very impressed with the ease of use however take your time to ensure you don't have over spill. The cartridge gun trigger has little resistance when you squeeze and the liquid can come back out causing a spillage.

Rated 5 out of 5 by from Beware Good product but beware of the cartridge. Always put the cartridge in the frame before changing the nozzle. I pulled the standard tip off the pipe to replace with a different one and at the same time as I remove the existing one the piston came out of the end of the cartridge. Inhibitor everywhere!! One saving grace it was in my home and not a customer's and in a wet room, so it all went down the waste.
