About to pull the trigger on the MaxCap 2:1 90gpd manual flush unit and I wanted to see if you could look at my water report and give me suggestions. I have a feeling that the water is very hard and the unit will be kept in my screened porch (tucked in a corner and shaded) and will sometimes be around 80 degrees. Water pressure is showing 65-70psi. Thanks!

Thank you for your interest in our products. My name is Jeremy, and I will be happy to assist you.

Will you email me the actual report? [email protected]?

Note: water hardness is a major factor in membrane life. We provide with our systems a hardness test kit that enables you to make a hardness determination used to select the recovery rate at which the membrane is operated. For example, in low hardness areas the system for optimal membrane performance should be operated using the green "low waste" flow restrictor (aka "2:1"). In harder water areas, the test will indicate if you should use the provided "hard water area flow restrictor" which is about 4:1.
Our chemist is going to chime in on your emailed water report, but from the 10,000 ft. level what I have said above will hold true for you.

May have a little problem with the unit. The black piece on the RO membrane seems to be leaking a bit. Only 5 or 6 drops of water per 5 gallons made but I can't seem to stop the small amount of leakage. Suggestions?

Also, I assume that it takes a bit for the membrane to reach full potential? I setup per the instructions and surprisingly the water hardness was only on the second color. I put the green restrictor on because of that result. First numbers are:

62 psi

In 214
Out 9
In 0
Out 0

Powder_blue,

With the leak please remove the black tubing from the input orifice to the membrane housing.

Then remove the black collet.

Then carefully remove the o ring inside.

Put a little silicone lubricant on the o ring.

Re-insert the oring straight, and also the collet.

Inspect your black tubing for a straight cut.

If it is not straight or the tubing is scored, cut the damaged or uneven off to make it straight.

Re-insert black tubing.

Turn on system to verify there are no leaks.

As for the membrane rejection:

Please measure the ml/pm on the product and waste for a minute and report back.

ps: after you insert the tubing into the fitting until it bottoms, tug gently outward to set the fitting's collet teeth to secure the fitting before pressurizing your system.

Black fitting stopped leaking after I pulled back on it a bit. I'll get waste water and clean water volume #'s to you tomorrow.

Readings this am were:

PSI 62

Out 7

Out 0

What is the waste water and product water measurements? 7 tds could be better from a 214 ppm feed.
