FYI, the very last step is to TURN ON the cold water supply and RO faucet lever for 10-15mins while the tank ball valve remains CLOSED to normal water stream to relieve built-up pressure inside the RO.

Do you have a source and recommendations for longer tubing?

For the small water line, it’s 1/4 tubing, available at places like home depot or lowes

run water thru the sed and the carbon before you run it thru the membrane, that way all those carbon fines want go in to the membrane

Good tip!

Thanks ! I usually fill the canisters w/filters installed 3/4 full of water then screw them on, maybe it makes no difference. It seems I’m back up running a little sooner. The RO water is used for my ice machine on fridge. Always a little nervous i could get air in that line but so far its fine. Any thoughts ?

I haven't had any issues yet. I think the air is pushed out thru the drain line when the filters refill.

I tried changing my filters about 3 years aga....wasn't sure if after changing them if I need to depressurize the tank. So I will try again with some help from my husband and his trusty air gauze. Thanks, and wish me luck.

Got quite the water setup in your house. Thanks for the continued maintenance videos. Good luck for 2021!

Our water is terrible. Without the RO system, we wouldn't be able to drink it.

I have had one of these for 24 years this is my second unit. I have a leak around the top of filter on it about a 1/2 a quart a day. I’ve purchased new o-rings from apec and the lube and it’s still leaking

The canister could be cracked. Maybe from overtightening or being dropped.
