Long time coming!

I installed this RO system along with moving all of our other well components to a new water shed. Turned the system on at midnight Sunday night and was producing beautiful water that still needed to be run through the UV light and remineralization filter. On Monday I buttoned up the wires/lines and adjusted the flow rates and float switches. Our whole house has beautiful water! Still flushing the lines on some fixtures (due to having salt build up for many years) but the fist shower was amazing! My only thought is if the booster pump/bladder tank had a higher output pressure. We have an 80psi well booster pump and miss that pressure. Other than that, I would most definitely purchase from you again.

Whole House RO / 165 Tank / UV / Remineralizer

Crystal Quest was great to work with. The system arrived without some of the install documentation but Crystal Quest was quick to email it over and provide support during the installation process. The black 165 gallon tank does have a strong odor and it can be smelt in the water in the beginning. I even washed it out with dawn soap before use. It's been in operation for a month now and the smell has been greatly reduced. I think this is normal break in stuff. Everything works great and I have had no issues. I wish they would have had an option for a DAB ESYBOX Pump versus the traditional booster style pump. But again.... Great system, great customer support, very happy!

The staff of Crystal Quest is great. Any time I called in they answer all my questions and make me feel good about asking it. My system is working properly and I am so happy that I purchased this from them.

So far so good, was delivered quickly and accurately. Easy to install with some experience.

A reliable system

Overall quality of the product is quite decent. The installation manual doesn’t mention that there is a need for a check valve between the tank and the pump. Otherwise, I recommend this product.

Quality product

I was surprised when I turned on the unit for the first time that water started leaking from carbon filter housing being that unit was quality tested before shipping. After tightening housing it worked fine. The only other negative is the slow delivery.

Questions about this product

Reverse osmosis produces water slowly over the day, so a storage tank holds treated water and a pump delivers it to the house at normal pressure. The 300 GPD unit is sold standalone or with a 165-gallon tank kit; the 7,000 GPD unit comes with a tank kit and a 1.5 HP horizontal pump.

Its targets include chlorine, iron, dissolved solids, salts, minerals, hardness and sediment.

Crystal Quest offers booster pumps, float switches, a TDS meter, a control panel, an auto flush valve and a recirculation loop. Call us at 908-787-6030 to add them before the order ships.

The listed replacement membrane is the 2.5" x 14" Freshwater Reverse Osmosis Membrane (CQE-RC-04111).
