Question: My filtering system keeps flushing and it seems as if the water keeps flowing instead of closing when the system is filled. What should I do?
Document: It was recommended to run about 4 gallons of water through it. This takes a while as it needs to build up a reservoir in the tank. After about 2 gallons, I tasted it and voila, pure clean water.The system seems to be good, but the instructions were useless because there were none. Hope this helps.
Find the expansion tank connection, I believe it's on the right side close to the IN connection. Connect a  plastic hose, at this point you need to decide if you want to flush the system before you connect the tank. I recommend flushing, so.. turn the water on. The first gush of water will be black, from carbon. I choose this route so the carbon would not get into my tank.
I followed the instructions and ran about 10 gallons through the final filter before using the water.I also added a quick connect "T" in the line going to my faucet AFTER flushing the system of carbon and ran one side to my faucet and the other to my refrigerator so I have clean ice and cold water. I did the flush first so I wouldn't have to flush the carbon through my ice maker for who knows how long.
The system was easy to install. I wish the directions would have been clearer. I had to look at the filtering diagram to figure out which filter went in which spot. Make sure you press the tubing in until you feel or hear it click into place or you will have as many leaks as I did. I had to wrap the tank fitting with 7 layers of teflon tape to stop it leaking.
This seems to be a great RO system once you figure out how to install it... The instructions that come with it are pretty poor. If you aren't familiar with a modest amount of plumbing, have someone else install it for you.A few clues to make this go easier for you:Not all the fittings that come with the system will necessarily work with YOUR current plumbing.The color coded tubes didn't match the instructions.
Instructions for a 4 stage RO with a 5 stage? Again had to research where the filters went. Someone re-write them for this dumb company! As far as leaks, I had none. I will check frequently just to be on the safe side. Not a plumber but it wasn't that complicated. Seems to be a decent unit. Getting some water testers though just to make sure my saltwater aquarium isn't at risk!
Then you can run any line cleaner in your lines, I did a 35 percent peroxide mix then flushed then vingar and flushed and finally line cleaner called blc bevarage line cleaner and flushed again. flushing with fresh water in the sprayer. It worked great for me and the water and ice taste fine now thats why im sharing this tip, hope it helps someone else.
If you want to throw away your money, there are better ways to do it.The product is more of a toy than a serious water appliance.The hose connections are flimsy and seems to be designed by a child. It leaks everywhere. DON'T install under sink or you'll have toreplace your cabinets due to water damage.
I installed this item and it functions just fine. The problem I have is that it is very temperamental as far as the hose and fittings are concerned. No matter what I do there seems to be a small leak.
The product is large and takes up most of the space under the sink. I wish that the main faucet were affected by the process instead of just the refrigerator and instant hot. Oh, well, uninformed buyers beware. Wish I had known before I bought it.
Answer: yes
