How do I put my pull out faucet back?

Under the counter there is a weight on the hose. If it gets stuck on something you placed in the cabinet under the counter then the weight can't help you put the faucet head back in the fixture. Check the cabinet under so that the hose and weight are free.

After turning water on to 10 year old grohe shower faucet pressure rapidly drops to nearly nothing

If you spin the shower head off there should be a metal screen inside. If it is clear, Soak the shower head in CLR for about 4 hours. After 10 years even the best water supply will leave behind a build up that can plug the tiny holes.

The thermostatic stop is set too low. Havent set a grohe before but most other thermostatic shower valves work similar. pull off the handle(however a grohe handle comes off . . ) there should be a notched ring or stop which keeps the handle from going all the way hot. pull out the ring and turn it a few teeth hotter put back and reinstall handle try water temp and adjust again if necessary.

The temperature in my shower is very luke warm only at the shower

Do you mean the other faucets in the house are hot and only the shower is warm? If so there is an anti-scald adjustment on the faucet that needs to be turned up a few notches. Havent adjusted a Grohe faucet but most faucets you rmove the handle and behind the handle is a nothced adjustment ring that prevents the faucet from getting too hot. This ring, or stop, is pulled out and twisted clockwise(or counter clockwise to set higher or lower max temp, then pushed back. maybe you can look up grohe to see which way ring or stop adjusts for hotter water.

Water flow is reduced to a trickle after only 2 mos. of use with the quick&heat water heater. we are in San Diego and water is nit that hard. Lawrence

Lawrence; there are several potential points that can reduce your water flow. Try these items and let me know. Check hoses under sink for any kinks.......take the aerator off the faucet and run water if trickle is still there then aerator is fine......check the valve that the water comes from and make sure it is turned all the way on. If these do not solve your problem let me know. Thx

Grohe ladylux faucet is loose

if you have an access panel behind it, take it off then wedge a peice of wood between the pipes and the wall, if you do not have an access panel take the cover plate off and wedge the wood thru this hole, do not over tighten just snug it you will be fine, remember to chaulk around the cover plate when done let set up for 24 hours

Grohe bath faucet adjustments

grohe is a faucet all by itself ,,, I would recomend to have you call there repair dept. and explain this to them, you said you put in the new cartridge and thats about all there is to it, when you put on the handle make sure it is not over tightened, sometimes it pulls on the cartridge and makes it come on by itself good luck

You need to flush your heater..or try to. This is going to be a minreal build you from what you are saying. I advise people to drain there heaters yearly in areas with water that has high minreal content. I hope it is not to late for you. The tools you will need are ; channel locks, and a flat head screw driver, water hose. There will be a faucet on the bottom of the heater. Connect the water hose to the end of the faucet, make sure your hose has a good rubber washer in it or you will have a mess from water leaking. You will want to disconnect the flex hoses from the top of the heater. The will break the vacum and allow the water to flow. You will want to run the hose out side. Try to keep it from going up hill. turn the faucet on. If you faucet does not have a handle and only has a notch you will need to use the screw driver. I hope this will work
