This is the second time that we have used David from The House Doctors to install a Dualflo Water Softener in our home. We have received a highly professional service and attention to detail in all of David’s work. We had a Dualflo Water Softener installed along with a new sink and 3 way water filter tap. The difference in our water quality is brilliant. No more lime scale build up in any of our kettles, washing machines, shower, taps and heating systems. The biggest difference is that there is no lime scale marks on the shower screen. We would highly recommend using a water softener to anyone. Thank you David for an excellent job well done.
