Get matched with top water treatment & purification system installers and replacers in Lansdale, PA

"Installed both a water softener and reverse osmosis system at my home. They did a great job with the installation, was professional, and ensured everything was working perfectly. Highly recommend their services for water purification needs!â"

"Though contracting/consultation was secured through Trident Water Treatment, the company Kel Tran Water Treatment completed the installation. The Technicians were well-equipped and experienced to complete the installation. Great Job !!!"

"The installer came to our home: explained how the system works, told us the cost and when we were ready, he came back and had it installed within a few hours. No more hauling salt, since he tested our water and found it was not hard so we didn't need a water softener"

"Joe was clean, prompt, and respectful of my home and time. The installation of both the softener and the RO system is neat and tidy. What a change in our ester after just a week! Skin feels better (not dry anymore) and we are using less soap for laundry and dishwasher. The RO water tastes great and I am saving money no longer buying 5-gallon water jugs. I would use this company again if I move and would recommend it to friends."

"The installation was done quickly and done well. The customer service was very professional. The only negative of this transaction was the cost of the project. It was the cost they told me it would be but I was just surprised that a replacement water softener system would cost that much. Overall I would definitely recommend this company."

"They were fast and willing to work with us on install of a replacement water heater."

"On the price, I don't, but it was also reasonable. They had also installed a water heater like a year before, reasonable. For sure they're a good service provider, any issues I have with the HVAC or my water system, I'll go to them. They clean up behind themselves; I don't have to do much."

"Always outstanding service from Valdel. Technician replaced external faucet.Don quickly, efficiently and professionally."

".We called our warranty company at 10:30.Jon and Ray came to our house at 2:00. They went to the front of our house to look at the drainage system as well as the drainage in the basement. <br />    They were polite and answered all my questions. I was very impressed with both of them. <br />   We paid $75.00 for a service fee for our warranty company so I am not sure what they charge other customers. <br />    <br />    If I ever have any problems I would definitely hire them again. <br />"
