United StatesWe started with the counter top water filter from RKIN and soon installed the whole house system. Big improvement in our water. Shipment on time but received broken part that RKIN replaced with overnight shipment. Installation was easy with step by step directions. RKIN was available by phone or e-mail to answer any questions or resolve any problems. I recommend this product.
United StatesInstalled this unit all by myself. Tank jackets are a nice touch to keep the tanks protected from the Florida sun.
This system doesnāt require any salt. Finally chlorine free water for showers and baths for grandkids. Our son in law installed it along with the undersink filter we got from this company. Highly recommend.
Had this system installed over a year ago. No problems at all. Also recently replaced our old undersink system with one from RKIN. Good
