Is there a way to speed up an ro filter. Mine takes like 20 minutes a gallon and I keep forgetting about it and wasting a bunch of water when I fill my jugs.

All you can really do is a pressure pump, but your membrane is going to be rated for only so much pressure. RO takes time.

20 minutes per gallon is actually fast. If you want to control when it stops running, hook up a float valve to the line that goes to the filter systems faucet and place the float valve in a tote or something similar for storing the water.

Weâre renovating a house and just installed a new tankless RO system rated for 500GPD (20+ gallons per hour) at the kitchen sink:
It wasnât cheap but itâs a lot more efficient that other models Iâve seen and used in the past.

Dummy me wasted water. Flooded my garage. Had to quit that.
These are popular econo portables.

20 is quick. Used to take me hours to fill a few 5 gallon buckets. Super hard source water dramatically slows it down. As mentioned, pressure pump or auto shutoff float valve is your only options.

Thatâs the filter I have. It works, I just need to keep an eye on it.

Yeah, my source water is pretty clean. 130ppm out the tap.
Adding more pressure to your RO system can lead to a catastrophic failure.
If you really hate waiting then just build a holding tank (with a float valve of course).

that thing looks sweet but I already bought the 7 stage ispring

I think Iâm just gonna be more attentive. Solutions seem to cost more than the problem.

@EugeneDebs420, if you already have a container to hold a quantity of water, all you need to buy is a few feet of 1/4" water line (the same your RO system probably uses), a âTâ connector for the water lines and a float valve like this:
That float valve is about $8 at Home Depot. You can get the water line and T connector for a couple of bucks. Seriously, youâll never regret spending so little on something that youâll utilize constantly.

I have a pressure booster on mine but the RO system is heavy duty with stainless steel membrane canisters. Not the home depot set-ups. You can actually build a set-up yourself. As long as youâre not doing recycling or multi-stage RO, itâs not complicated to build a system. The most expensive items are the membranes and the booster motor.
It make a huge difference being able to produce around 5 gallons in less than 10 minutes. Add larger membranes or membranes in parallel and the time drops, as well.

Thatâs mine. Out of the box should get you about 10-12gallons an hour. Itâs a slow drip when itâs filling, but it will fill a 5 gal in about 25minutes or so. 300Gallon per day.
Does your ro system have a water pressure meter and is it at the correctly psi?
