Rated 5 out of 5 by from Good product. Unbranded direct replacement BWT canister. I have two separate appliances each served by these which are replaced effortlessly as recommended every twelve months. Top tip - make sure the small feed holes in the pipe fixing are thoroughly cleaned and if necessary drilled out to ensure satisfactory operation before fitting the new canister, otherwise it won't work properly!

Rated 4 out of 5 by from Not cheap but it works I first bought the branded version of this for our Vaillant combi boiler about 25 years ago. The boiler is still going strong and these cartridges do help with the very hard water supply in our area. However the price for the cartridges has gone up and up over the years, as have the fittings.

Rated 4 out of 5 by from Good product, hard push fit. These are the same as the Combi-care canisters, but I always wonder why they are not a screw fit. I find both types are very hard to make the push fit connection. Once fitted, they seem as good as the Combi-care.

Rated 1 out of 5 by from Poor fit Using this replacement for a combicare branded can gave me plenty of issues! Compared to the branded can, the nozzle fit was very tight, and the locking collar was much more snug, so there is virtually no rotational 'wiggle room' which helps to engage and disengage the can. Also i struggled to fully engage the can (not helped by the above), meaning when i turned it to lock it in place, the metal elbow fitting shaved the edge of the plastic return on the can off. i had actually removed the metal fitting to clean the delivery holes and bores of any remaining scale as they are very prone to this (a design 'feature' of this system, 2.5mm drill at the ready), so wasn't expecting such a difficult install process of the can itself!. What should have been a ten minute job became an hour of faffing, removing o rings, dressing the edges of the nozzle etc to avoid damaging o rings and getting it to fit. I ended up fitting the can to the removed metal elbow fitting and then screwing the fitting to the pipe adapter in the end it was that tight, rather than risk overloading the pipe adapter part. I'll buy a branded on next time, its not worth the additional time to deal with the various problems encountered above.

On removing the top of the cartridge it broke at the neck, how do I remove from the chamber?

I’ve tried using a screwdriver to chisel it out, but it’s difficult as it looks like it’s melted and just breaking up into tiny bits of plastic. Any ideas?

I have picked one of these from Screwfix and the insides are rattling like there is broken parts inside is that correct ??

Asked by: Anonymous
This is to be expected. The cartridge is full of Polyphosphate crystals, these are loose inside and will make a noise if shook.

how to change

Asked by: neil10000000
Changing the Cartridge (Please follow the steps 1-12 in order) 1. Turn off the water and drain the pipe down. 2. Place bowl under the Combi-Care unit to prevent any water spillage. 3. With a flat headed screwdriver, loosen the pressure relief screw on top of the control head. 4. Unscrew the cartridge locking screw. 5. Turn the cartridge a quarter of a turn to the left and gently pull downwards, releasing it from the double ‘O’ ring seals. 6. Remove the indicator ring. 7. Remove the protection cap from the new cartridge and place it over the top of the old cartridge, thus preventing any water spillage. 8. Place the indicator ring over the new cartridge and dial it to the current month. 9. Insert the new cartridge into the bayonet fitting and turn it a quarter of one turn to the right. 10. Tighten the locking screw 11. Tighten the pressure relief screw 12. Turn on the water and test for any leaks. Cartridge replacement is now complete.

Length.

We need to replace ours but cannot find the original size that fit. Ours is sat on top of meter so the canister i size can be no longer that 14cm. What is the length of this please?
Asked by: Elsy
The height of the system, including fittings, is 220mm.

Noisy

Hi I replaced my combi care cartridge (different brand) and now there is a grinding/vibrating noise whenever the hot water is on. What’s causing this? Thanks
