Grohe 28 819 000 Shower bar slips out of brackets

The bar slips down since the two wall mounting brackets do not grip it tightly enough. A black grip handle is supplied to lock the bar and prevent this but it is not effective

SOURCE: Grohe shower assembly leaking

hiit sounds as though the diverter valve is sticking in the mid position although you have turned it to the floor spout as you call it!!
Also it sounds as though the seals are possibly leaking causing the plasterboard (drywall) to get we, or possibly a joint may be leaking. Advice access the pip-work valve etc run shower & check with torch (flashlight) to see where its coming from?
Rectification work replace seals/repair leak...replace diverter valve assembly.

SOURCE: Grohe hand held shower head stopped working

This is a simple fix. The tools you need are: cresent wrench. You want to remove the shower hear off of the pipe coming from the wall. On the inside of the end off the shower head there should be a small plastic disk remove it. It will have a series of holes this is called a water saver. The holes get stopped up with minreals take a tooth pick and clean them out. I see this all the time. If that does not work it will be in the valve

SOURCE: leak where Grohe shower head attached to the threaded pipe

using a pair of vice grips wrapped in a soft towel( to prevent scractching) turn the shower head in a counter clockwise direction to remove it then apply liquid teflon (real-tuf) to the threads on the shower arm and tighten the shower head but dont over tighten it liquid teflon is more effective at sealing leaks than teflon tape and it can be wiped clean

Install grohe shower bar

After removing from wall by unscrewing long screws after removing cap, look inside and you will see a white translucent plastic with 4 wide, flat hooked ends. Take a small screwdriver and gently push each 4 plastic hooked ends and it will come unhooked from the small groove. Push it far enough that the bar will slide out. No need to remove the plastic hooked piece. To replace, push in each hooked end and push in from the opposite end to reinstall.

There may be a tension adjustment screw on the slider that you can adjust to add tension between the slider and bar. If it is an Axor or Hansgrohe wall bar You can call Hansgrohe Technical services. We can help you identify and adjust or reapir this unit. Feel free to give me a call at 1-800-334-0455. Ask for David Scarborough. I'd be happy to help.

Moen 3836...lost installation manual...what size drill bit for the hand held brkt.

There is no single answer that I can give you because it will vary due to material you are mounting to. If you are going to be mounting on ceramic tile or fiberglass shower wall I would recommend you use the plastic anchors that come with the bracket and mounting screws. Use drill size 3/16 drill holes and insert anchors. Mount bracket and screw in place. If you have hollow wall with nothing but sheetrock to hold the bracket I would get small butterfly anchors from hardware store and drill hole slightly larger than the wings on fastener when they are folded back along side the screws.If you have a wood backer board behind shower wall then drill holes with 1/8 inch bit and use screws long enough to reach through shower wall and sheet rock and mount bracket. Hope this helps you. Thanks P.S. If you have to drill thru ceramic tile you will need a carbide tipped bit.

I have a Grohe 28917 Relexa Ultra Five 24 Inch Shower Set, and it is not mounted well to the wall so that it is loose. Also, the slide bar also goes up and down too easily. Can you help me?

the 2 mountings have caps on them, pop them off to get to the screws. If the plugs in the wall are busted you can use spring toggle bolts and it will give you a very strong mounting. Just don't over tighten to the point that you damage the wall.

The slide bar may need rubber cleaned since soap scum will make it slippery. Do this while you have the bar off the wall.

Leak where Grohe shower head attached to the threaded pipe

Hello, Many shower heads have similar problems. (Very frustrating as you now know) The problem is the threads at the end of the (cheap plastic) shower neck are not flat. They are tapered (has an edge) - so it does not seat flush with the base of the shower head. Actually cuts around the rubber washer causing a leak.

What to do about it?

File the end of the neck some to create a flat surface. However, go slow. Be sure you can still screw on the shower head. Add a flat rubber washer in the shower head and plumbers tape on neck threads too.

Or Purchase a new shower neck that has a better design. The neck should unscrew from the front. Check and make sure you have an access behind the shower just in case you need to access the plumbing.

I replace the shower neck myself if there is an access.
