I wont be able to do any plumbing cuz I rent the place. Landlord comes back checking things out very often.. It's sad man..

so as long as the water has 0 PPM TDS reading would be fine for reef right?


LOL that really not plumbing work ,it should take you as long to hook that up as you hooked it up to your faucet plus i dont think he would notice it

This is the flow restrictor on the waste line. Make sure it is turned the way as shown. I bet that's the problem.

I do not have that black switch on my unit and it is optional when I purchased from a guy on Ebay. The manual says if the waste line gets shut off intentionaly, it would permanently damage the RO membrane.

So are you saying I should install a valve on the waste line and shut off the waste line completely while the unit is producing R.O water? This should speed up the R.O water production?

Thanks

You need that valve ,youe RO unit will create 1 part RO water to 3-4parts waste water ,not having that valve will just keep flush the majority of the pressure thru the waste water line ,Shuting it will let more water flow thru the filter and let what ever waste water that it need to drain out .

only time you open that valve is to flush out your membrane

Ronen

Im gonna have to ask a stupid question,,didnt this unit come with instructions ? It not that we dont want to help you ,but it may be easier for you to see how the manufactor want you to install the unit or set it


RO units need pressure and that valve for it to work :) But since you said it didnt come with it or didnt need it .so its confusing

The instruction says there is a valve to control the waste line but I don't find it on my unit. It also says I should let the waste line going to the sink while the unit is producing the R.O otherwise it will damage the filter.

I haven't seen where it says I should shut off the waste line while it is in operation. However I might overlook it.

Anyway I will try it again tonight. Thanks

There needs to be a restrictor on the waist line. If you take out the waste tubing from the unit and theres nothing in the tubing to restrict the flow all of your water will go down the drain insted of pushing it through the membrain.

Vic

But the it needs the waste line water flow freely in order for the unit work properly. I found this info on the internet and in my manual.

R.O unit also wastes a lot of water too.

I am getting distilled water for my tank..

The flow restrictor does not shut off the waste line. It restricts the flow of the waste line end of the filter to create back pressure to produce RO water. If your unit does not have one, that's the reason why it is not producing much RO water. I guess you bought a lemon. You need to buy one that is rated for your unit ie. 110gpd flow restrictor.

Does your waste line have one of these?

I think this one has one end attached to the auto-shut off and other end attached to the waste line. But I don't find a black switch on it.

But there is alternative to this by puting a valve on the end of waste line tube, the value that comes with the unit. A white water dispense value for the R.O water coming out of the unit. I think I can use that on the waste water line.

Hi guys,

I didn't find any distilled water in my local store. I only found some Spring water and Purified water (stated purified by Reverse Osmosis), some of them are mineral added to boost nutrient.

Can I use these water?

If I test the water using a TDS meter and result turn out to be 0 PPM. Is that mean the water is safe to use?

Go to a supermarket and get distilled water, Rite aid and duane reade sells it too.

That is the flow restrictor then. One end attachs to the shut off and the other to the waste line. There are different types of flow restrictor. The one with the black switch works pretty much the same except it allows you to open up the valve to flush the membrane while the one without does not and you have to disconnect the restrictor in order to flush the membrane. Don't use the other valve for the waste line. It won't help. I suggest you get someone who has a RO unit nearby to check it for you to see what exactly is the problem. Like other had said, it could be the water pressure also if it is not the flow restrictor.

I have couple things would like to share with you guys.

1. I got one gallon of DW from Duan Reade, it costed me $1.80 after tax. I thought someone said under $1 per gallon. :grumpy:

2. I install a R.O water dispensing valve on the waste water line and decrease the flow to dripping and I still don't see any significant improvement on the R.O water production rate.

3. The tap water pressure is very low here, just found out about it from someone who also keep reef lives in my area. so I figure it probably the low water pressure is the culpit of the problem.

It takes about 1 hour to produce one gallon or R.O water and three gallons of waste water..

If this is the case then you're OK. The ratio of waste to good is about 4:1.

Did you rotate the unit to get most of the bubbles out. Basically pick it up and turn 90 one way and then 90 the other?

I have the exact same model as you and it takes around 3 hours to fill up a 5 gallon bucket. I leave the bucket in the kitchen sink so if it overflows, it just goes down the drain. I also noticed if the water is warm it will flow faster than just using cold water.

I haven't yet turn the unit 90 degree.

The weather is cold in NYC. so it's impossible to get warm water unless I turn on the hot water

BTW, why would you guys prefer DW over Spring water? I believe the TDS reading would be 0 PPM from any spring water too.

Spring water is not the same, and will not have 0 TDS. They all have some dissolved content. It's just fresh water collected, filtered for sediments, sterilized, and bottled. In fact, some spring waters have more dissolved contents than NYC tap water. Distilled water is just that, water distilled by boiling and condensing the steam, leaving impurities behind that have a different boiling point. However, even distilled water may become contaminated through the distillation apparatus itself (there is always the question of whether distilling apparatus with copper piping could leach copper into the water, although I haven't seen any tests on any brands to confirm this).

So, RO (/DI) or distilled can be used, but RO(/DI) prepared at home is economically superior to distilled. Sorry, but spring water won't cut it. Then again, there are some people who do use treated tap water and get away with it for awhile, but with all the money invested in SW, why chance it? NYC tap water is fine for my FW tank though, as a python hooked up to the sink sure beats carrying the buckets around at water change time.....
