Question: Could this system be used as spot free rinse for car washing?
Document: Not enough for as a whole house system (I believe, unless it's a very small house), but maybe more than for a residential under-the-sink use. (Perhaps this is why some use it for green houses, car washes, and the like.) With infrequent home use, there is a delay to when the pump kicks on and thus we have to wait several seconds for the pump motor to begin circulating.
The main thing you need to know for installing this system is that the 3/8" flexible pipe is used to feed with cold water. There is a plug on the 3/8" opening you have to remove in order to connect it to the system. There are stickers that tell where the drain water goes (1/4") and where the RO faucet goes (1/4" as well).
You need to cut the 1/4" pipe to your needs. In my case, however, I used a blue pipe from my previous RO system for the drain water so I won't use the drain pipe accidentally if I move to a new place ;)I have to disclose that I had a little problem with my last stage filter, the polishing filter. I noticed that it took quite some time for my TDS reading to get low.
I purchased this system for my mobile detailing company. The water is absolutely pure and makes detailing 100 times easier. I bought this system after using DI water, which was awful in comparison. I set the ispring system up to be automatic to fill a 275 gallon tank and another for the bad water which is used to water the yard, plants, pool etc. I did have a slight leak in the main membrane and called the company and sent me replacement parts in a few days!
I bought this tankless RO system because I got tired of maintaining a water tank - checking pressure, sanitation etc. I finally got fed up when the tank of my previous RO system stopped filling at all. Could it be the shutt-off valve? The bag inside the tank? I thought it's enough! There should be a tankless RO system with a decent output. I didn't want to buy those portable RO systems where you get only a trickle and need to wait an hour to fill a gallon jug.
I tested the water flow of the new system by timing how long it took to fill the same12 once glass of water at the OR faucet. It took 35 seconds!Conclusion: neither the new nor old RO system produce an adequate flow for filling a glass of water or driving my new  refrigerator ice/water dispenser, let alone washing windows or cars.
Because I use more then most, I change filters much more often. I must say this is the BEST RO unit I've used to date. The booster pump makes this a far superior unit.
This product was easy to install and is working great, however I am some what familiar with RO systems and the instructions provided could be much better.
It is also smaller than Merlin.Cons: I'm getting around 310 GPD, less than promised 400. The installation instructions could be better, my prior experience with Merlin installation certainly helped here.
Perfect for Aquarium use, restaurant, office, window cleaning, car wash, green house, and coffee shops.&#8221;  I read this and thought to myself &#8220;If the ISpring RCB4T provides a sufficient pressure for &#8220;light commercial&#8221; and can produce an sufficient flow for a restaurant, coffee shop or to clean windows and cars, then it ought to be more than adequate for making ice in my new frig. I was so wrong!
Answer: no
