So simple
5 Dec 2015

" This was so easy to use.
Made up adapter to suit radiator.
Let pressure and a little water off system.
Removed bleed screw.
Fitted adapter to clear tube, snipped off to fit securely in radiator. MOST IMPORTANT.
Screw on can & wait to empty.
Refill, system.
Hey presto done.
I like things that are well thought out & executed, this product is one. "

Sludge remover

" I can't really get excited about sludge remover - what can I say - I squirted it into the radiator as per instructions - I presume it did its job - no way of telling really but at least it showed the wife that I was willing to do DIY jobs around the house. "

Usual Sentinel product.
27 Dec 2013

" I have used Sentinel before and found it works, so I am not reviewing the product but the applicator.
What they don't tell you is it will not work with the bleed valves that have a hole at the side to direct the water away like the ones you get on ladder rads! I followed the instructions to the letter and as soon as I turned the valves back on and expected the little rubber bullet to seal the end a 4 foot jet of water shot all over me and the bathroom!
After mopping up (and repairing the rad valve that had decided to leak as well after operating it) I tried a normal type rad. I must say it worked well with little spillage, but be warned!! "

Great product, poor applicator
10 Feb 2016
By

" First the chemical product - can't be faulted. Only added it yesterday (can be left in a system for up to 4 weeks). Although the system was to all intents and purposes "clean" - it had a Magnatec fitted and was maintained with X100, the system is now running much quieter and the radiators much hotter. Can't wait to see how much gunk comes out as it's a long time since I used X400 and the Magnatec takes care of all the larger particles, of which there are very very few ever! So will be interesting to see what comes out of a relatively "clean" system. Definitely made a difference though and will be using it again.
Applicator - as for the applicator - very disappointing. As another poster noted, it's very hard to achieve a seal and by adding the contents of the can you are re-pressurising the radiator so I hate to think what will happen when you pull the nozzle out it's push fit and so requires you to totally remove the rad bleed valve end. Won't seal on vented bleed valves at all. In the end, I abandoned it, took the top off the magnatec, syphoned it dry then filled it with the contents of the can which comes out as a stream rather than an aerosol (one small consolation).
I could have used a professional screw in Sentinel brass filling loop into the magnatec valve which is non return were it not for the fact that Sentinel don't include any adapter that will screw to their own professional chemical filling loops!!!!!
Overall, therefore chemical can't be faulted. Aerosol system very flawed. "

" Not sure how much went in the radiator so will have to treat again, the applicator is very poor and struggles to seal properly "

Poor quality x400
15 Feb 2016
By
, Glasgiw
" Bought 2 can of rapid dose x400 for my 16 radiator combi system with 200 litre capacity. Dosed through filling loop when system pressure 1 bar. First can dosed fine, could hear hiss as system dosed and can empty after 30 sec or so. 2nd can after initial quick hiss failed to dose and remained full of product. Duff can and ordered replacement, but still a pain in the bum having to wait 2days for delivery. Sentinel equivalent much easier to use. Is this why they are on offer? "
