RO System Conversion Kit with Quick Change Filters 75 GPD PT4000T75-RK

Great find

"I bought our house with a Culligan RO already installed. When it came time to replace filters I learned they were nearly impossible to find. I called Culligan and they sent out someone to replace my filters. Every went well until he told me the price. Sticker shock to say the least. A year went by and I had kept trying to find another way to get replacement filters. No luck! I called Culligan again and had 3 filters replaced and again ridiculous price. Shortly after I stumbled across the ESP conversion kit online. When replacement time came instead of buying from Culligan I bought the ESP conversion kit. Two days later it came and within an hour I had a new system for less than Culligan replacement filters. Works great water taste clean and pure. I’m so Happy! Thank you ESP"

Very good conversion fit and great filtration

"3 things that would have made it better for me: (1) my old Rainsoft system didn’t have the same color coding, so it was a bit difficult to figure where the tubes go, took me a while but was ultimately successful, (2) I don’t have a the hooks to hang it on, so they stand under the counter, but the membrane filter is slightly longer than the others, causing it to be unstable, better if all cartridges were the same length, (3) there is a tube at the bottom of the membrane, this will make switching out the cartridges more difficult, luckily only needs to be done every 3 years…. Thanks for a great product otherwise."

Successful conversion

"Our first contact was with Edward and he was helpful and knowledgeable and the order was placed. We received it and had second thoughts about our ability to install this but called customer service and Tim was able to walk us through it. The only hiccup came when my husband removed one of the plugs from the unit and the small gray O-ring came with it and because the system would not work we had to stop. Tim said because the part was broken we had to buy the replacement part. Because your company was out of the elbow fitting your company would have to send a different fitting. We did receive the fitting 5 days later and were able to finish the system but because the replacement fitting was not an elbow the top Purotwist cover does not fit. We are extremely happy with the system but not the fact we had to pay twelve dollars to replace the part that simply came out when he pulled out the plug and wait 5 days to receive it and the fact we will have to cut a piece out of the cover to make it fil properly. We are very happy with the fact we don’t have to buy over priced replacement cartridges. This is the second time I have completed this review as the first it would not submit back to you. I reached out to Tim to see is it was received and he said he didn’t know as he doesn’t see them. I asked if he could check and he said you probably got it. So far so good with the performance of this unit. Kris DeBerg"

Easy conversion and great tasting water!

"This conversion was super easy. I used it to replace my Rainsoft manifold and filters. Everything was plug and play with the exception of the hanging screws for the manifold. My water tastes better than before, is it seems to flow faster, and I will be saving on filters for years to come. No brainer to switch to this system."

— Julie B. (5/5)

Just as goodas the expensive alternative!

"The conversion kit wasn't cheap but the savings on the filters will certainly make up for it. Water tastes great and no subscription is needed to get filters, I love it!"

package was complete, everything was

"package was complete, everything was packed in the box. Install went quickly although instructions were not very clear. Individual filters were not marked, all were the same so had to guess which was which."
