How to Repair a Grohe Faucet Hose

Grohe has been producing faucets and other bathroom accessories since the early 1900s.

Most Grohe faucets all work they same way: by carrying water up through a hose from the water supply to the faucet. Occasionally, these faucet hoses can leak or sometimes burst. In that case, you'll want to repair your Grohe faucet hose as soon as possible.

Turn off the water at the supply valve for the hose that needs to be repaired. This is usually underneath the sink where the Grohe faucet is installed.

Wipe off the faucet hose with a towel and make sure that it's dry. Take a piece of sandpaper and lightly sand the outside of the hose. This will help give the tape you will be applying a better grip.

Wrap your repair tape spirally around the hose about 2 inches below the leak. Plumbing repair tape works well, but electrical tape and duct tape will work in a pinch.

Wrape the tape until you are at least 2 inches over the hole. Cut the end of the tape.

Turn on the water and use your repaired Grohe faucet hose. Make more permanent repairs as soon as possible.

Permanent Repairs

Turn off the water to the faucet hose that needs to be repaired. Open the faucet to allow any water to run out.

Cut the hose with the shears just below the leak or break. Use the adjustable wrench to unscrew the coupling that holds the faucet hose to the water supply.

Cut off the portion of the hose attached to the faucet that has the leak or break. Try to leave as much of the original hose as possible.

Insert one end of the coupling into each of the cut ends of the hose. Tighten the clamps to hold the repair couplings in place.

Wrap the outlet on the water supply valve with plumber's tape (this is plumber's tape for pipe threads, which is different than plumber's pipe repair tape). Reattach the end of the hose to the water supply valve beneath the sink. Tighten with the wrench.

Apply plumber's tape to the threads on the coupling. Screw the repair coupling together. Tighten with the wrench.

Turn the water supply back on. Run the faucet. Check the hose for leaks.
