What our customers have to say about us
18 Oct 2023Great 3-way tap, which was well packaged, with clear instructions. Our plumber commended the tap as good quality and easy to plumb in and connect to both water supply and under-sink filter. Looks brilliant in our new kitchen. Thanks to Fountain Filters for a helpful website and speedy delivery service.
12 July 2023Great product, simple to install including hints on common installation challenges which I did have and overcame instantly because of the care taken by the seller. Whole of house now has soft water without a noticeable drop in pressure. Has made a massive difference throughout.
1 Dec 2023It was a small but important order: replacement o-ring with silicon for my water filter housing. when I told them I had not received the articles after 7 days, they without fuss dispatched a replacement with the result I received the original and replacement 3 days later! Very responsive customer service.
17 June 2023After moving into a property with a fresh water supply, I turned to Fountain Filters for advice on replacing the water filter system. I purchased the Moby Twin Sediment System and it has been a worry-free system. Even changing the filters was far easier than the old system. Cannot fault this company on speed of service or quality of advice.
