Hansgrohe Recent Questions, Troubleshooting Help & Support

Hello david41139, This is a sign the spray face is getting clogged or slowed by water deposits. When this happens it will slow the water going through the venturi in the head and begin to express water in the areas it would normally draw in air. The first thing to try is to soak the spray face in CLR. Follow the instructions on the container for use of the CLR. It will most likely instruct you to dilute. Then rinse the head well. Reconnect the head and run water through it. While running you will need to rub the rubber water channels in the spray face. Then repeat the process at least two more times to remove all the deposits. If you need any further assistance give me a call at 1-800-334-0455. Press 2 for tech and ask for David. I will be happy to help.

I would suggest that if the low flow is affecting the hot water only that the filter is restricted where the tap plumbing joins the house plumbing. The filter is in a small housing which is right next to the house plumbing. Turn off the hot water supply and ensure the mixer is in the off position. Disconnect the hose adjacent to the house plumbing using a 19mm and also a 10mm spanner to stop the thin hose twisting. Then use a 13mm spanner to unscrew the filter housing.

Almost certainly the hose. They leak from the bottom, cartridges drip from the top. That unit is discontinued. https://www.manualslib.com/manual/13802/Hans-Grohe-35807801.html https://www.google.com/search?q=Hans+Grohe+35807801+kitchen+faucet+parts ..

Yes you need to replace as a complete Cartridge Repair Kit. Once they wear, you can't fiddle with them and make them better.

identify the source from hot or from cold or from both. cold only suggests you may have a rusty water service supply pipe. this pipe is outside underground. hot would indicate corrosion at your water tou may have a copper system but it;sheater. both hot and cold would possibly indicate galvanized nipples were used to stub out of the wall under your sink, and are experiencing ionic transfer...or electrolysis...if its your bathtub you are talking about and not your sink faucet,,,,the color is very common and is occurring because your tub spout and showerhead were piped with galvanized pipe. a lot of plumbing shops pre-fab their tub valves with galvanized pipe and supply the valve water with copper tubing....just grin and bear it if so. one more idea if it is your faucet and it occurs on both hot and cold use...check the screen in your faucet aerator...the little chrome (or brass) tip that screws on and off the end of the spout on the faucet. good luck and if you see corrosion on any supply connections...handle with care...the pipe or fitting could be very brittle or soft...and break apart...causing a flood....make sure to know where and how to turn your house water supply off before going beyond a visual inspection of your plumbing..orange water indicates corrosion of steel pipe 99% of the time and bkue water indicates corrosion of copper pipe 99% of the time.

I have the same issue with the same model faucet. The suggested link is dead. Anyone know of a means to remove the "frozen" nut?

That sounds like an issue with your either The cartridge or your handle needs to be reseated correctly . Turn off your water turn the tap to the on position find a set screw should be a small Allen key before turning out make sure your drain is plugged in case the set screws falls all the way out loosen your set screw till it’s almost all the way out remove your handle check to see if your Handle possibly had not been seated correctly. There are YouTube videos to show you how to reseat your handle properly it’s not that difficult. If it’s not a handle issue your cartridge likely needs to be replaced which is also an easy process .

You could measure flow with spray head attached, then remove head (see link) and measure again to see how much the head reduces rate of flow. You could try removing the check valve(s) but not sure if that will work as it may leak. product features · consists of: single lever kitchen mixer · swivel range 150° · with telescopic function (330 - 500 mm) · normal and spray jet · lockable shower spray, spray returns through pressing spray diverter · quick connect shower hose · flow rate 6.7 l/min · ceramic cartridge · connection type: G ? compression · integrated non-return valve · suitable for continuous flow water heaters

no it wont, you need a washer where the leak is coming from

Contact Grohe about a repcement. Looks to be defective.

Loosen the faucet and rotate it away from the window sill until the handle clears.

NPT and NPS are the same. Screw away! If your female thread is plastic and your male thread is metal, you must be careful not to overtighten as overtightening can crack the plastic on the female thread. Good luck, and don't forget your teflon tape. 4 to 5 wraps is good unless you have heavy duty gas piping teflon, then use less.

Check your cartridge and seat if your not sure what they are you can you tube it I'm sure there would be a video explaining how to change them. It is not very difficult.

undo the nut that holds the shower head on ( bit behind the ball) and inside there is either a rubber washer or a fiber washer replace that and do it up
