Rated 3 out of 5 by from Water pressure is very poor The flow of water from this filter is far too low. It promised 1.9 litres per minute (not a lot), but only delivered 1.2 litres per minute. I think the tubing is far too narrow and the provided saddle fails to create a large enough hole in the copper pipe. . If you have lead pipes, then you don't have much choice - this is the only readily available kit, but the performance is severely underwhelming. . The saddle also leaks when set to the 'off' position.

Rated 5 out of 5 by from Excellent piece of kit! Excellent piece of kit and easy to install. If you have a stainless-steel sink with a drainer and the tap between them, mount it on the other side using a Spiral Flute Step Drill (8528D) which cuts through very easily. Only installed yesterday so don't know about reliability yet.

Rated 3 out of 5 by from Poor Pipe fitting not as illustrated on web page, the web page shows a wrap a round fitting , water flow only gives a maximum of 1/2 litre per minute. This was installed by a professional plumber.

Rated 5 out of 5 by from Great diy filter kit We have tried several water filters over the years. This is not the cheapest, but definitely the best we have had. The kit is easy to fit and replacement filters are readily available, need to replace after 6-9 months as water flow slows.

Thread Size?

Can you tell me what size the fittings are that attach the flexi pipe to the tap tail and to the saddle clamp please?
Asked by: Jimbo652
The red tubing is 6.3mm (1/4"). The 2m red tubing comes readily attached to the saddle valve. In regards to the tap, the thread of the tap is 7/16". The tubing comes attached to the tap - so the purchase of a connector is not necessary . Kind Regards, Rachel

Fitting to an Existing Tap

Hi, Can this filter kit be used with an existing standard tap? I have a Single Lever/Mixer tap, and want a filter kit that can go under the sink but basically bolt-on. What's best? What additional parts would be required? Thanks, Luke.
Asked by: LukeF
The BWT High Performance Water Filter Kit is supplied with a filter head with 1/4" push-fit connections - for the saddle pierce valve with flexible tube on the inlet, and flexible tube connected to tap supplied, on the outlet. If you do not wish to use the tap supplied with the kit you would need to be able to connect the 1/4" flexible tube from the outlet to your own tap using a suitable connector. This would be 1/4" push-fit to whatever size thread your tap is.

Filter capabilities

Would this filter be suitable for installation after a polyphosphate system? Would it remove the polyphosphate fixed / coated minerals? Thanks.
Asked by: G4George
The BWT High Performance Water Kit is suitable for drinking water. It will not be an effective solution to remove polyphosphate from the water. A polyphosphate dosing system will dose food grade polyphosphate into your water. Although this is safe to drink, people with a sensitive palate may detect a slight taste in the water. Therefore, it would be recommended to install this after your drinking water supply to offer whole house protection or install to protect a single appliance. If you wish to remove scale from your drinking water then we could recommend to use the BWT Water Filter Kit (product code: 14306). This drinking water filter kit reduces chlorine, unpleasant taste & odour, scale and scum.

I have a 100 year old lead pipe supply to my drinking water. Will this filter remove high levels of lead so that the water is suitable for drinking?

Asked by: MrsCravatt
Whilst our High Performance Filter kit will remove trace elements of lead from an approved potable water supply it is not suitable for applications where the level of lead is likely to be significantly higher either because of the water source or the pipework though which it flows. Whilst there are commercial solutions to lead removal we would always advise that the lead piping is removed and replaced with new pipework in accordance with The Water Supply Regulations 1999 (and its subsequent amendments) in order to ensure that the water supply can be made suitable for drinking.
