Tim and the other employees go out of their way to assist you in problem solving. Additionally, the service is exceptional and the pricing more than competitive. I have been a customer for the last few years, and would not use any other business for my filter needs.

Outstanding customer service. I ordered the wrong parts. I contacted the company, they had me text pictures of my current parts, told me what to order, and then after I received the corrected order, they walked me through install.

This was my first time ordering online from ESP Water, and it was a very positive experience. A representative emailed to make sure that I realized that the posted shipping time for my water softener o-ring purchase was 6 weeks, and inquired whether I wanted to continue with the purchase. I had not realized, and so appreciated the extra step they took to confirm. Now that’s excellent customer service, and not often found these days! I did proceed with the order as the part was not needed immediately, and true to their word, my order arrived within 6 weeks. This is a very reliable, trustworthy site, and I would not hesitate to order from them again.
