Get matched with top water treatment pros in Allentown, PA

"Enjoying our new water treatment system. Our old one was leaking. Now we have a new stainless steel system in our basement. Our salesman, Scott, was very friendly and helpful. I would recommend this company to anyone who us interested in a water treatment system."

"Water softening, treatment, and conditioning system installed cleanly and neatly. Met my expectations. Happy with the result. I would have preferred that the installer put down more floor/carpeting protection and worn covers over shoes to better protect flooring."

"Father and Son team installed a whole house water system . The quality of work was old fashion which means arrived on time, had all the extra parts needed for the installation on the truck, finished up within the estimated time, left the area cleaner than they found it, billed as estimated, and waited until the system worked to my satisfaction. (Iâ  ve got to say the son looked like he worked harder than the father. )"

"The technician came on time and, although it took him longer than expected to install the system, he installed it and demonstrated the system for me. The next day, I noticed there was still water on the concrete close to the system but, I figured it was residual water. Apparently the system was leaking. Two days after install I contacted Leaf and advised them that the system was leaking. Early, the next business day, they arrived and repaired the leak and made sure I was happy. My system seems to be working well and I am satisfied."

"The morning that my well pump stopped working and water did not flow into my house, I had called them and they came out that same day to do the repairs. They are wonderful, well priced and very experienced! I would absolutely recommend them to anyone!!"

"They did a great job and a reasonable price. The plumber was excellent thank you"
