new RO/DI unit arrived...WHOOOP.....just a small question

I would research that brand for reviews and go from there. Looks like it will give you an extra 20 psi but I can not speak or read French, although I wish I could

 

iv found the site, in fact its the same one suggested by skyvern (aquatech) the site where i might buy it from however does not specify the PSI boost. been trying to find the same model pump but cant seem to get my eyes on it.

nvm actually on the picture i showed before you can clearly see its written aquatech not tec, fake?

 

Answer the question on whether or not your unit has a flow restrictor installed in the waste line and what you meant by installing a faucet somewhere. You may not be plumbed correctly and a booster pump may not be needed.
Have you actually measured and adjusted the waste ratio to see if that was your peoblem? If everything is going to waste the certainly you would have low pressure. Have you checked your TDS to see if the waste is approximateiy 25% higher than the tap water TDS which is another indication of proper waste ratio.

You need to do some troubleshooting first before investing any more money on things you may not need.

What is your tap water pressure static with nothing in the home running? What is your water temperature? What is your exact measured waste ratio? What RO membrane do you have?

 

ill post picture tomorrow to better depict what im saying but ill try and answer some elements now.

i dont believe i have a restrictor on my drain
the water that comes out of my faucet is normal cold water i would say roughly 10°c?
my filter membranes are composed of 5 micron filter units
there is quicker flow of water from in the drain line, or at least so it would seem compared to my old unit. however there i could regulate the flow of the drain. it was a little valve you turned that would (im assuming) allow more or less water to pass through said line.

that faucet story i added i can better explain tomorrow with a picture together with the plumbing.

otherwise if i hook everything up and let it run i reach roughly 10-15psi and this is regardless to the faucet i set it up on.

how would i test the ratio? fill two containers and when the outlet reaches 1 liter i see how much water came out from the drain line?

thx for the help AZ

 

Use a measuring cup and measure the waste flow for exactly one minute and note the amount. Then do the same on the treated flow for exactly one minute. Adjust the valve or whatever you have on the waste line so you end up with as close to 4:1, waste to treated, as you can get. This should keep your pressure where it needs to be as it is all going out the waste line and not through the membrane now.

 

right well here are the pics.

i didnt measure the ratio yet but by eye it would seem about right.

according to instructions
white line=inlet
yellow=outlet
orange=drain

only thing i can turn or regulate is a little valve (thats very hard to turn) just next to the pressure gauge.

 

and some more pics...

btw after having emailed the shop asking for further information they replied saying its UP7000 model by puricom...so i did a little background check...clearly the image of the pump is not the same but this would be the pump supposedly...seems like a good stuff

If the orange line is the drain or waste line, it should have a flow restrictor in or on it somehwhere to make the water osmose through the RO membrane. The flow restrictor provides the backpressure ro make this possible.

If you look on page 6 of the attached RO/DI manual you will notice the waste line should be the line closest to the outside edge of the membrane housing where there are two lines, the one closest to the centerline of the housing is the treatred water line, usually blue in color on most systems worldwide. Is this where your lines are located?

Disconnect the waste line and look in the end you disconnected for a short piece of very small tube, it will look much like a strand of spaghetti with a small flange on one end and will be inserted inside the line. If its not that you should see a small white housing with something like 440 or 750 mL stamped or printed on it. Both are examples of flow restrictors. If it does not have a flow restrictor it will not work and looking at your last photo it appears the treated wate ris running much faster then the orange or waste water which is just backwards. That plus both are running much too fast, a 75 GPD RO/DI system at 50 psi will have a steady drip coming from the treated line and a slow stream from the waste line and both yours appear faster than that.

 

......-.-.....how do you remove these easy fit clips...they are hulk proof

i may not be the brightest bulb in the chandelier but...this makes no sense to me.....

never mind it makes perfect sense....


so could the faucet idea used before be enough of a restrictor?

the flow of filtered water is really slow

Looking at the drawing either on page 6 or here:

Where it says "end view for membrane" you will notice the two lines coming out of the membrane housing. The one closer to the middle of the housing, blue in this case, is the treated water line which should then go to your horizontal DI and the one closer to the outside edge, yellow in this case is the waste line and should have a flow restrictor of some sort either inside the line or an external restrictor. It has to have one somewhere.
