Low flow Grohe Ladylux faucet

I see a ring on the end of the spout that looks to have threads that you can unscrew to check and clean the screens. If you still don't get a full flow click on back. Good luck, Tom

I'm not sure if you've solved your problem, but I wanted to share my experience. I've been suffering with poor flow from my Ladylux faucet ever since I installed it 6 months ago. It was taking me 10 seconds to get a pint of cold water from it. I had repeatedly cleaned the screens etc to no avail. Today I bit the bullet and took the thing apart. Flow was the same speed from the hose without the sprayer on, so I figured the problem was upstream. Took the cartridge apart - no blockage. I took the hose off and let a pan fill underneath the faucet (where the snap hose connector attaches). LOTS of water. I had a look at the snap connector. It seems to have some sort of flow-limiting valve built in. Took out my drill and drilled out the valve to a diameter of maybe 3/16". Put everything back together. End result = no leaks and I can fill a pan of water in seconds now!

Disclaimer - I bought the faucet on ebay. The snap connector is red and black. The replacement parts I have seen online are yellow and black. I'm not sure whether my connector is intended for v high pressure situations or is ex-display. Anyway, the limiting point in this faucet seems to be built into the upstream hose connector. Hope this helps someone.

The connector is the problem. Push the insides out from the red end and you can clean out the debris that is blocking the water flow. Thanks for the help

That Quick Connector is also a spring loaded Back Flow Preventer. It prevents dirty dish-water from being siphoned back into your house plumbing system.

It can get clogged up very easily with debris flowing through your house plumbing. By drilling its interior parts out, you canceled the functionality of the Back Flow Preventer.

Also, the handle has back flow preventer built into its threaded end.

Grohe faucets are very fine and delicate product. If you have galvanized pipes than the problem may re-occur.

I don't understand the reference to eBay. EBay really has nothing to do with it....

Glad you were able to trouble shoot your kitchen faucet yourself ! Milo

My wife broke the plastic stem on the 8 year old hand piece of our Lady Lux Plus so I replaced the hand piece which took about 2 minutes but the flow rate was always low (sometimes very low). After months of trying to clean it out to increase the flow rate I unscrewed the hand piece one day and took out the white plastic piece which is at the bottom of the hand piece stem. I assumed it is a flow restrictor. I then look out the small black o-ring in the restrictor and put everything back together. The water flow increased by 10X and the faucet works like it did before the hand piece replacement.

After several months of frustration with the volume from my new used ladylux I did as Chappers did. First I took the backflow preventer out of the pull out sprayer. This was easy with some needle nosed pliers. However, this did not increase the volume noticeably. Then I drilled the backflow preventer out of the quick connect. This proved to be quite difficult because the parts immediately started spinning around in the quick connect. It took my some time and finesse to get it all cleaned out without destroying the O-ring that seals where the spray hose screws in. Though I suppose that even if you wrecked that O-ring you could just use teflon on the threads. I reassembled everything and yee haw - I am in business with all the flow I could want! Thank you Chappers!

We never put the spray unit down in water and even if we did, what are the chances of water EVER being sucked back into the unit? I'll gladly sacrifice the backflow "protection" for useable flow!
