What Our Customers Say

Quick and professional installation. I couldn't believe the water taste! Our water had a not very pleasant taste and a super-strong Chlorine odour. That's all gone now. Plus, no more plastic waste from bottled water! Highly recommended.
Sebastian Slotwinski, Dublin 16
Don’t usually write reviews, but am so impressed by the new Clack water softener installed by Celtic Water Solutions, felt I had to. I did a significant amount of research regarding the different types on the market and came to the conclusion that the Clack system was the best….by a mile. Well all I can say is: get a clack system installed by Celtic Water Solutions, “THEY WORK, THE DIFFERENCE IS ALMOST IMMEDIATE“.
Paul Stoneman, Drogheda, Co. Louth
Before getting our under-sink filter installed by CWS, I suffered from severe mouth ulcers & stomach upsets, also occasionally headaches. Water from our filter tastes great & I drink much more now, bringing it to work too. In two months since it was installed all three symptoms have cleared up! I’m delighted with the product and friendly service. I am recommending CWS to friends & neighbours.
Mai Byrne, Kiltegan, Co. Carlow
The system is brilliant. Limescale is finally gone from my house. Taps and showers are so shine and clean that I can use it instead of mirror. The whole process from talking to a salesman to installation was a pleasure. Quick, professional and friendly. Whatever was promised, was completed. The installer called a day earlier to arrange for a suitable time and arrived on time. The job was nicely done and no mess was left behind. I can’t recommend you enough. Fantastic service and the system! Thank you for the good experience.
Viktorija Petruchno, Johnstown, Co Meath
Absolutely delighted with Celtic Water. Haven't bought bottled water since it was installed. Would definitely recommend them. Neat job. Came when planned and the water tastes amazing.
