Some Reverse Osmosis Questions

We have a new home under construction in the remote mountains of Colorado.
In our new home, our water source will be a well and our sewage will go into a septic system. Our current home has a reverse osmosis unit so we have some knowledge of those devices.

On Wednesday of this coming week the drywall contractor will start closing the walls and ceilings. We will probably want reverse osmosis drinking water to be available at the Kitchen sink and at both sinks in the Master Bath. The Kitchen is directly above the Mechanical Room. The Master Bath is above a storage room.

Culligan Reverse Osmosis Aqua Cleer

i have an under the cabinet culligan aqua-clear three stage system.
the serial number on the back is ac 10057618 and it shows ac30 premium, ac30m, and ac30l.
i believe its two filters and a reverse osmosis cartridge.
What are the replacements needed for this one?

The Culligan Aqua Clear RO filters all use the same granular activated carbon pre-filter, the same activated carbon post filter, and the same particulate filter.

However the reverse osmosis module/membrane varies between the units.

Also, the size of the post filter is different.

I’m trying to locate a replacement reverse osmosis membrane.
The labels says: FASTEK MEMBRANES, Model TLC-18, S/N 8285-0059.

Fastek Membranes are standard sized units. Same as the Desal osmonics (with a different label).


Little or no water from RO faucet

This is in regards to the TGI Reverse Osmosis 625UP/DX 6 stage 25 gpd 2gpm SS UV with Pump/ESO Purifier.
It was purchased back in December and and it now broken.
The pump does not stop and the water does not come out.
Please fix this ASAP. We do not have water to drink!

Your system is still under the warranty and TGI Pure is known for their prompt response to defective products.
However, although you’re eligible for the warranty we don’t know what the problem in your system is.

REVERSE OSMOSIS unit makes water flow slow

When I put in (replace) the 15 gallon per day Reverse Osmosis membrane, I lose water pressure to almost a drip.
Is this normal?

It’s possibly one of the following three issues:

REVERSE OSMOSIS UNIT Makes water slow.
o Normal R.O. process.
– Your 15 gpd Reverse Osmosis water purification system makes water a drop at a time. 3 gallons storage tank should be full in 6 – 10 hours.

o Low water pressure.
– Increase to 50 psi. Check for kinked tubes.

o Filters clogged.
– Replace filters.

o Membrane not installed correctly.
– Ensure installation is correct.
