I have to admit that my brother told me about TwinTec, since he had a water softener fitted in his house in Liphook and is a complete convert to softened water. He thought his came from a firm in Havant, but that was too far away. So I googled TwinTec and up came UK Water Softeners in local Frimley. A phone call later and Kevin Goody was round to look at my flat within a couple of hours. 30 minutes later we had done and dealt. That was Thursday and it was fitted at 9.am. the following Monday. In the meantime I had had a confirmatory letter saying when the system would be fitted.
I cannot recommend the service I have had from Kevin highly enough. Most people who know me are aware that I am totally intolerant of inefficiency but this was the diametric opposite! I shall certainly let all my friends and acquaintances know of this very simple device. It may cost more but in my experience you get what you pay for in this life. What is more if you move you can take the unit with you, if you want!
