AVOID

onMay 16, 2010

for the fact that they do NOT carry the "reverse osmosis membrane" in stock - apparently it's a special item that no one ever orders so they don't bother to stocking it.

...and the screw around at the parts department to find this particular item left me cold.

Laste only 5 months

onSeptember 14, 2009

Worked great for 5 months then had to be sent to Toronto for repairs. The automatic shut off stopped working.

We have relied on Sears for many many years for good products & service, not for this R.O.

I think for only working for 5 months they should send a repair man or replace.

Cons:Â Poor quality

Answers

A:Â

Yes you can mount the entire unit and storage tank under the sink. The dimensions for the filter set is 13 5/8" high 13 1/2" wide 4" deep, and the storage tank is 14" high 11" diameter. You can use the faucet included and hook it up to the fridge with additional fittings available at a plumbing supply store.

chlorine taste breakthrough

Q:Â

I purchased this unit 7 months ago and I changed the pre/post filters about two months ago as the indicator light went off. Now we have a chlorine taste in our water and I remember that the manual said this could be a membrane breakthrough. How can I get a new membrane cartridge and should they last a little longer than 7 months?

The membrane is available through Sears Parts & Service. Please refer to your owner's manual for the toll-free number. Membrane and filter life depends upon incoming water quality. If you would like more information please contact the Kenmore Water Line toll-free at 1-800-287-0756.

reverse osmosis hook up

Q:Â

can this system connect directly to the fridge water dispensing system rather than using the faucet provided? also how much is the r/o filter, how often does it need replacing, is it hard to get? (the sears location nearest to us had the other two filters but not the r/o filter)

Answers

A:Â

The system can be connected directly to the fridge however we do suggest that you have your water pressure checked to ensure proper operation of the water dispensing mechanism in the fridge. Please contact the Kenmore Water Line toll-free 1-800-287-0756 for more information. The ro membrane is available through Sears Parts, and the cost is approximately $100. It needs to be replaced on average every three years, and this is dependent on your water quality.

basement install to feed main tap

Q:Â

Hi,
will there be sufficient water pressure flowing through the filter system if I install this unit in my basement to feed the waterline going directly to my kitchen tap?

Thanks,

A:Â

The ro filter system has a dedicated faucet, and you can install the filtration unit in the basement. It is not designed to supply the conventional kitchen faucet.

water waste

Q:Â

Is it true that with an RO system you waste 3 liters of water for every 5 treated?

Posted:Â 1 year, 5 months ago

Kellyap

Â -Â Devon

(read all my Q&A)

Answers

A:Â

The average for most RO systems is 4-5 liters of waste water for every liter of pure water produced. The reason that the RO produces waste water is that the purifying membrane is being flushed in order to keep from being clogged by the fine contaminants that the system removes.

625.75680-1 Manual Sought

Q:Â

The tap on our R/O system (Model 625.75680-1) I have had a heck of a time finding a new one. Once I did, the tap has only the fitting for the water from the filter. The one I am replacing has 3 connections. Is there a diagram on-line to show how this is all connected? Where can I buy a replacement tap?
