"Have fitted a couple off these and cant believe anybody would fit a new boiler without one off these installed ,after all you wouldnt buy a new car and put your old cars dirty oil into it which is what your doing if you fit a new boiler without a filter,totally recommend this filter as it removes all impurities not just the magnetic ones"
"This unit is well made, fits well and is compact. The instructions are easy to follow. The only issue I had is that it leaked at first and some how it seems that I had overtightened the connection of the main unit to the adapter tube (by hand). I removed and resembled and it now works fine. I haven't check for debris yet but I'm confident than it will collect everything it is supposed to. The whole system is running quieter already."
"Reason for purchase - to replace a broken magnetic filter of another manufacturer; Two leaking isolation valves and one of the threaded connections snapped off in the brass coupling to the bottom valve.
Sentinel filter has quality valves coupling to large diameter stubs on filter body, so inherently stronger construction.
It uses both Cyclonic and Magnetic separation, so should pull most dirt particles out the system.
The drain lever assembly must be reversed before attempting to open drain valve. As yet unable to ascertain its cleansing ability."
"I used this unit recently and it looked fine out the box, although big for many cramped installs. The system was duly drained and pipe cut ready for the unit. Then the fun started. None of the supplied valves worked freely and the bowl was almost impossible to remove, even before install. Once in position turning the valves or removing the bowl was going to be almost impossible.
If the pipe hadn't already been cut it would have gone back at this point. If it's in a cramped space forget servicing in the future.
Also to dose the system with anything you drop the bowl and fill it with the inhibitor etc. Unlikely as its almost impossible to get off and you can only dose half a litre at a time... So for a litre you've got to run the system. Drain the bowl now you have heated everything up. Drop the bowl and repeat. Useless!
There are other products out there don't save £10.00 and make any install and service painful."
"Like the other reviewer said, its quite a bulky filter. The one I fitted to a new boiler install also leaked all over the floor due to the large O ring in the top not having been fitted correctly from manufacture. A quick strip down of the filter soon rectified the problem. But its not the best advert for a product when the customer can see water coming out of a new install."
"I have installed 4 of these over the last year believing in the words of manufacturer about dual capabilities of the filter (magnetic and non magnetic filtration). Recently I was called back on the job, 3 months after installing the boiler. The internal filter of the boiler was blocked with particles which came off the pipework and which I would expect to be trapped inside the CH filter- that's it's job- to catch the things before they get inside the boiler. This filter had just a few smal particles inside of it all of which were magnetic bits size of the grain of sand. All the bigger things got trapped inside the boiler. The system was flushed after the installation, long story how these particles got into a circulation, but that's not the point here. The point is that it looked like this thing has done nothing to prevent or at least reduce the amount of debris getting inside the boiler. Fitting this product is a waste of time in my opinion, unless it makes you, or your client feel better. I am really disappointed because it really looked like a quality product but turned out to be useless. After this experience I wonder now how other brands products "really" work, hope they do otherwise we have a plumbing scam of the decade where people are being charged £100 for a plastic jar which does nothing."
