Living with the Lowes Whirlpool Reverse Osmosis Water Filter


Reverse Osmosis water Faucet

It’s unfortunate in some areas that tap water can’t be made to taste better.  Where I live the water has so many chemicals in it, it almost makes you thirstier.  I decided to install the reverse osmosis system for both  environment and health reasons.   I was buying gallon jugs of water for the longest time. Half of them tasted like plastic which probably  was leaching harmful chemicals into the water. Also I was sick of wasting gas and time driving to the store when you can get water out of your tap.  Plus I have heard it takes 2 gallons of water to make a plastic jug.  What a waste of water! Because of the initial cost and price of the replacement filters, it seamed like it would be hard to get any return on the investment but now after using it for 6 months it’s hard to believe we lived with out it.  I purchased the unit for $155 on sale at Lowes. To make the current faucet work I had to order extra parts from kohler to change my faucet from a three hole into a single hole unit.   Lowes also sells different finishes of drinking water faucets that work with this system so you don’t have to live with the chrome faucet.  It doesn’t have a battery filter change reminder but you can sign up for email filter change notification to change your water filter every 6 months.  Two of the filters ($45 for the two filters) need to be changed every 6 months while the reverse osmosis filter ($59) should be changed once a year.  The biggest complain I have heard about these reverse osmosis systems is that it appears that a lot of waste water goes down the drain. When I initially installed the reverse osmosis system I ran the waste water drain directly into the sink drain.  All night I could hear the water running and gurgling in the sink while it filled the tank.  The next day I ran the waste drain into the basement  so I wouldn’t have to listen to it drip all night.   For about a week the water ran and ran.  I ended up calling whirpool about the excessive water consumption and they had me take the system apart to look at the gaskets.  It turns out my gaskets were not working properly so they sent me another whole unit. Once the new unit was installed everything worked great.  I would bet there is about 3-5 gallons of waste water everyday but I believe as with any reverse osmosis filtered water there is a similar amount of waste water.  I’m thinking about eventually running the waste water to a rain barrel outside.  Since the water draining was noisy  I would recommend running the waste water into a drain in the basement if possible, it may have just been my old plumbing but I didn’t like hearing the water trickle down the drain.  

Reverse Osmosis System

After using this system for the past 6 months I am extremely  happy with it.  The water tastes better than most bottled water and I never have to carry those water jugs again. I wish the filters were cheaper but the convenience of water from the tap is wonderful. Also I feel that even though there is waste water I’m probably wasting less natural resources than I was before. Also I drink much more water than I ever did before. Now I’m wondering if you can recycle the filter cartridges?

Hi, Where can I get a filter for my Whirlpool Model WHER25 RO system? I had it installed last February and it is calling for a filter change but I can’t find one, not even in Lowes where I purchased it. Love the machine. Had one up in New York and it’s the first thing I installed here in Florida.

You should be able to find them at lowes. If they don’t have it in stock ask them to order it for you. The RO filter will be by itself & the post and pre filter will be together. Otherwise you can order them on the lowes website at http://www.lowes.com/lowes/lkn?action=productList&N=0&Ntk=i_products&Ntt=wher25

You can also go to ecodyne.org/rof and that will take you to the Whirlpool site for this RO system. You should be able to find a filter there.

We bought our Whirlpool WHER25 system one year ago. While I agree, the taste of our water is vastly improved, I must say that the ongoing dripping of the waste water. Unfortunately, we are not able to run the line down to the basement and as a result I am constantly hearing the dripping water. Had I been aware of this ongoing problem prior to buying and installing this system I would not have purchased it.

Where can I get the Filters #WHERF and Membrane Cartridge #7264223 and
Diaphragm Kit #7250876 and Plunger & Spacer Ring Kit? I appreciate your help.

You can call whirlpool / ecodyne to get parts and filters. The number is 1-800-986-3223

I want to stock “one ahead” replacements for my RO 25 system. I cannot find date codes on the stock that Lowe’s has. Any idea of the ’shelf life’ of these membranes? Thanks.

I have the WHER25 RO system. I have had it about 2 years. This time when I changed both filter the water flowed very slow, so I also change the Membrane. It still runs very slow. Any Ideas as to what I can do.

Make sure you have the little plastic flow control inserted into the drain tube. Also make sure your membrane isn’t deformed I have one that looked normal but never sealed correctly. Best of Luck.

I have one of the RO units from Lowe’s. It does what it is supposed to do, but if you let the water run all the time the filter is working all the time, night and day, and won’t last long. I have a lot of dissolved solids so that my membrane is only good for a month . I installed a shut-off valve. Jim G.

If the water runs all the time it could be possible the membrane inside the unit may be defective or your incoming water pressure may be to low for this unit. I like your solution to the problem though. If I get a glass of water the unit will drain the gray water for around 2-5 minutes.
Thanks!

I have a wher25 filter system.
It has started leaking severly out the side breather hole. I changed the filters, no luck!
I checked the drain, it’s not pluged!
What next?
I need an exploded view as to how this is put togeather.
I am an engineer but without guide lines I might damage the unit.
Is there a gasket kit? Help!!

Hi Robert, Try taking out the screws on the base unit & see if there is any blockage inside the unit. There aren’t a lot of parts inside, it’s mainly the gasket. If you need a new gasket or any other parts you can order parts at http://www.ecodyne.org/rof/index.asp?tab=4

I just installed the WHER25 system and am extremely disappointed with the incredible waste of water it produces. It has been running for 36 hours straight, including the initial setup purge and sanitize cycles. Even though the tank felt full last night, this morning it was still running and dumping gallons and gallons down the drain.

I am not going to bother calling Whirlpool, because even if it isn’t working properly now, which I suspect is the case, I can not accept a system that runs for several minutes after pouring a glass of water as someone mentioned above. We use 2 gallons of filtered water per day! I know that just from this short experiment with the WHER25 we are going to see our water bill affected.

Back to Lowes it goes.

Myself included, it’s incredible that with these internet resources we don’t research our purchases better. I knew the unit wasn’t silent and wasted most of the water and didn’t like high solids. I didn’t know it won’t tolerate Iron in the water supply. After using them for 6-7 years I doubt if they are cost effective. Filter replacement=$175.00 p/yr.,(paid $200 for entire unit)so you better know how much you’d spend on bottled water p/yr… BEFORE you buy. As for convenience…it’s not that inconvenient to buy RO water at grocery store, ’specially if you can’t buy filters conveniantly. Shipping costs need consideration. Sounds like the public could use drinking water

Somehow goofed my post. To continue: I wonder if the public would benefit having, say a mobile RO/drinking water service deliver into your bulk storage system? Convenience… and probably cheaper than in-home RO. Probably being done somewhere.

concerning the whirlpool wher25 reverse osmosis system; does the yellow blinking light mean it needs a filter change? a membrane change? We inherited this system and could use some help. thanks

Yes, the blinking light means you need a filter change. It is timed for 6 months of use so if it doesn’t get used much the filters may be still in good shape. Here is a link to the manual http://www.ecodyne.org/rof/index.asp?tab=4

I have this model. The flow will be strong for about 3 cups and then slow the about one half of a pencil size. Very annoying when you are trying to get a 12 cup coffee maker to fill. I changed the filters hoping that would cure the problem. I didn’t. I then purged the tank thinking it was water-logged. No improvement. What is my problem?

The pressure on your water storage tank may be wrong. You should be able to use a tire pressure gauge to check it. Call the manufacturer to find out what the tank should be at. Best of luck.

I have this unit as do a few friends and relatives, or similar units.

The gurgling is normal, and in most or all places it is code to run the drain up to the faucet, creating an air gap, then to the black tube to the drain to ensure a backup doesn’t get in your drinking water, making it even louder. Many ebay or DIY installs don’t use the 3 plug method, but a single pure water line to the faucet, and with no problems.

On filter replacement, I would not routinely change filters or membranes, but would monitor the TDS weekly or monthly. Some folks (well users) may need to change filters and membrane more often. Others with city water, may get a few extra months filter use. If your TDS is not any higher than when new (ours is about 3-9) I wouldn’t change filters until TDS started increasing to 12 or 15, and it was over 6 months. Again, talk to your local plumber about this, unless they make money on selling filters …

How do you measure the TDS (Total Dissolved Solids)? Do you have to use/buy a conductivity meter or are there small cheap kits that can be purchased say at a fish store?

When changing the pre and post filters, is it really necessary to ‘purge’ the system for 24hrs? I could understand running a couple gallons through, but 24hrs seems like a waste.

Hi, I have a Lowe’s Whirlpool Model WHER25 reverse osmosis system. The system is roughly a year old and it is leaking around the dispenser faucet at the sink. Where can I get a replacement?

I have a WHER25 which works well but is noisy. There is a noise coming out of the air gap at the faucet. And the constant dripping while it is refilling. How do I get rid of the air gap noise?

The only way to get rid of the noise is to run the line to a basement drain that you won’t hear dripping. It is a very annoying sound.
