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

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.

My shower is leaking and i have tried a new pipe with washers what else can i do

Did you use any teflon tape on the shower arms threads to seal it up. Also check and make sure fitting on shower head isn't cracked once tighten up onto shower arm it could have a crack in it and leaks. Plastic shower heads tend to crack when they are tighten to much.

Just wondering How to turn the water pressure down on a single knobb moen shower fixture? Thanks

unruly is right....if your shower valve is the model that has those isolation valves built into it...If yours does, you will have no problem seeing them once the cover plate is off...If there is no sign of any bulging fittings on each side of the valve, with a slotted drive stem in the middle of each one looking back you, directly in the eye, then you have to take a different approach to solving the pressure problem.
That approach will cost you the price of a new shower head...because that's your only remaining option, (short of hiring a plumbing contractor to install a couple of flow reducing fittings or isolation/metering valves on your supply piping)(a five hundred dollar bill will buy that option), available for a FIY project. A new head can be purchased for under 10-12 bucks....just make sure to take your old one with you when you go to buy the new one....this will identify the means in which your shower head attaches to your shower arm pipe. It wouldn't hurt to pick up a small jar of pipe thread compound or Teflon tape too. Some shower head re-attachment applications require a pretty snug fit to prevent leaks at the connection joint. You see, there will be more pressure on that connection now, because the new shower head you bought has a restrictor built into it, thus your water pressure issue is resolved, but that added resistance also causes higher pressures in the shower arm and piping supplying it inside the wall. That is why you should use thread compound or Teflon tape on the threads when you re-install the new head. ...And also, the threads on the shower arm have been used once already, which deforms the threaded area slightly, making for a loose-er fit when re-used. The Teflon tape can take up the space by adding a couple extra wraps on the threads. And before attaching the new head, paint a light coat of pipe thread compound on top of the Teflon tape, (brush it on in a clockwise direction only...the same direction you rolled the Teflon tape onto the threads)(and take care not to get any pipe thread compound inside the shower arm....the flow orifice in your new shower head will be sensitive to any debris that try to pass through it)(it will be prone to clogging)(and it will continue to slowly clog as time goes by...another reason to do the in-line valve option,.... and require being flushed out occasionally), and that will surely give you a good tight seal. Not to be too commanding, If I could Just suggest one more thing.....Please use a smooth face wrench, (like an open end wrench or adjustable cresant wrench) to tighten chrome finished fittings and pipe. If you have to use channel locks or pliers in the place of a strap wrench, get one of your best wash cloths and wrap it around the pipe or fitting before gripping it with the jaws of the pliers. If you have a might want to keep the wash cloth thing between us guys, but it really needs to be a cloth wit a thick layer of material, otherwise the pliers will pinch right through and be useless....if you have a leather shammy....that would work the very best...
Well I lied....there is one other option, if your real attached to your present shower head, you could purchase an in-line shut-off valve and install it directly behind your shower head, on the shower arm. It would have to be an in-line globe, (best)-needle, (good)-or ball, (okay), valve type of configuration, so you could adjust the flow to a more suitable volume/pressure. Because the new shower head will not be adjustable and you will have the pressure reduced to the set gallons per minute setting that the head was designed and manufactured to flow at. Get a nice chrome plated brass bodied in-line valve, with a globe type valve design and install it just up stream, (directly behind), your shower head and this will be the best DIY option you could take. I would definitely opt for this method to reduce my water pressure out of the shower head....because it not only allows me to adjust the pressure to just the way I like it, but it also makes me a proactive part of conservation of our fresh water supplies, by allowing me to easily turn off the water flow while I lather up with soap, then easily turn it back on to rinse.....This option may cost more around 30 bucks, and it may prove to add a degree of difficulty toward finding the right in-line valve, but I think it will pay for itself in the short/longish run. If you have a "mom and pop", locally owned hardware shop left in or around your town/city, I would suggest looking for the "best" in-line valve there. A shower head in-line metering/shut off plated brass body, 1st-globe valve configuration...2nd-or needle valve....lastly-ball valve configuration, it must have a stainless steel stem and handle/lever for easy operation, and the connection configuration must be 1/2" FIPS inlet side and 1/2" MIPS outlet side for best results, mechanically and aesthetically. You find yourself this exact valve and it's a done deal. Or just get a new head and bing bang bam...pressure problem fixed.....just like that. good luck and may the Plumb Gods smile upon your efforts.....

ps....peel off the excess Teflon tape and wipe off the excess pipe thread compound when you finish attaching you new head/in-line valve. Beautiful...pss...there are a few web based retailers that sell hard to find fittings and valves the in-line valve I've suggested...I can only remember a part of one of the retailers names....McMasters and???. that should get you there.

I haven't had a lot of experience with Grohe brand but have had twenty eight years as plumber, 22 years as master plumber and the bottom port of every tub or tub/shower valve that I installed used the bottom as main supply port.

The shower head has a leak around the ball area

Take the showerhead off above the ball. You may need to hold the pipe with one wrench and turn the showerhead with the other. Put teflon tape on the threads that are exposed on the pipe and then put the showerhead back on as tight as you can get it.

I am installing a Grohe 35015 shower valve. I bought threaded adapters to mate with my 1/2" pipe. Do I solder the threaded adapters or just tighten them? I am concerned about the heat damaging plastics.

Be concerned and follow manufactures recommendations. Often you make sure any plastic seats are not closed if soldering the valves.

The only connection for copper pipe I know of that aren't soldered are either the flared fittings OR the compression ones using the littl "ball" type collars.

Grohe ladylux plus is leaking

I believe there is a cartrige that has some washers in the unit. There may be some debris caught in there since it was a little loose. I would turn the water off and disassymble the unit and replace any obvious washers and clean everthing up. Replace it all and try it again. If it still leaks, contact Grohe for more trouble shooting. Faucets have fantastic warranties and companies usually will send replacement parts free of charge at times. Hope this helps.

Walk in shower leak into room below

I would unscrew shower head pipe and either pipe dope it or tefilon the threads and then reinstall it. I would also take the handle(s) rosettes off and look for a leak from there with a flashlight, while shower is on. I believe the most comon leak for walk in showers are the door seals. Are you sure it is not coming out from under the door? Another test that yuo may want to preform is to Stopper the drain, fill the shower pan with water and watch for bubbles, or look for leaks from below.

Dripping shower head

If it is dripping from the connection where it goes to the water spout you can unscrew the connection and wrap teflon tape or Pipe Joint Compound on the Threads. Now you can Thread the Shower Head Back on, with No Leak. IF..... It is leaking from the Shower Head Itself There May Be a Problem with the diverter handle/lever. If it has a Pull Type Lever, sometimes you can screw the Lever up or down for the proper water restriction to the Shower Head. However if the Hot and Cold Handle/Lever is OFF, There should not be any Water coming out from anywhere! If water is coming out off the Tub Spout, with the Shower Off, then you will have to replace some washers or Cartridges in the faucet(s) to stop the dripping. You can do this easily....Just Ask) Remember though, that some shower Heads may Drip for a Few Minutes After they are Turned off. There is still water in the Supply neck and needs to escape, either though the tub Spout or Shower Head.......Hope this Solution Helps you with your Drips.....Joe

Tub shower combo... newly installed but leaks from shower head when turned on

Some shower heads require a rubber washer that would fit in the opening in the shower head. That may be all you need and would be the simplest fix. Check that first.
Sounds like you need some teflon tape available at any hardware store. The teflon tape should be wrapped around the pipe threads with 2 or 3 wraps and then screw the shower head on to the pipe. If the leak is in the wall, remove the shower head pipe from the wall pipe elbow and apply 2 or 3 wraps of teflon tape to the shower head pipe threads and reinstall to the elbow in the wall. You may need a pipe wrench if the pipe is real tight. Good Luck
