Diamond Spring water tech produces a crisp, pure and exceptional tasting water. I have never been a great fan of bottled water and have always been happy with straight from the tap. However, this water purifier system has converted me. Taste the difference and BUY IT! James is a charming man, his service and attention to detail does him proud.

I was just thinking about that very subject 5 min ago, as I was dunking a teabag!  

I’m pretty sure that the tea brews fast and darker with the new cartridge.  I certainly like the taste, must say!

Richard was here and simply commented that he liked the taste of the water. The taste is obviously different with the new cartridge. All Best!

James Warnell at Diamond Spring has given me consistently good advice and service over the years. My water purifier produces top tasting water and is kept in good condition with regular servicing by Diamond Spring.

Diamond Spring has supplied and serviced water purifiers and in two of my houses over the last thirteen years, their products are of excellent quality, very good value and their friendly efficient service is first class, nothing is too much trouble.

I have no hesitation in recommending them.
