How do install delta shower

If you are looking to replace only the shower head, you'll need two plumber's wrenches, a cloth, and Teflon tape.

First and foremost, read the install instructions that come with the new shower head...

After you clearly understand what the instruction's say, shut of the water supply lines for the hot & cold water.

Take one of the wrenches and apply it to the neck of the water supply tube coming out of the shower wall (a.k.a. goose neck or supply nipple, or arm, depending upon the design). It'll have male threads (the threads are on the outside of the fitting). I would place a cloth of some sort around it before placing the wrench on it so you don't mar the finish of the water supply tube.

Place the second wrench on the shower head assembly (which has the internal, female threads). and unscrew it by turning the shower head assembly counter-clock-wise (to the left) while holding the water supply nipple with the other wrench.

You need to do this, so you don't snap or deform the water supply nipple coming out of the shower wall- and/or possibly causing leaky damage to the fittings behind the shower wall.

To replace the shower head, you reverse the removal process- the only difference is, you wrap Teflon tape around the male threads of the water supply nipple before spinning on the new shower head.

Somethings to be careful of, and I can't stress this enough, DO NOT cross thread the new shower head onto the water supply nipple. You should be able to screw it on the new shower head by hand- where it is hand tightened- then using the double-wrench method that you used to take off the shower head, turn the new shower head an additional half to three quarter turns with the wrench, clock-wise; and I mean gently.

Here's a nice short video on the subject, illustrating my instructions:

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 just installed the valve new. I have a shoewe head and a hand held that feed from the unit. It was intended to 1) serve the shower heas alone, 2) serve the hand held unit alone, 3) put water to both...

Assuming that your two heads are fed from the typical curved wall mounted shower pipe, what you need is a diverter valve. Removed both heads till it's down to just that curved pipe. Get a diverter valve from a plumbing supply store. Tell the sales folks that you want to install a diverter valve so that in one position, the hand held receives water and in the other, it cuts the hand held and puts it to the reg. shower head instead. They should give you a "T" sort of fitting. The female threads of this screws into that curved shower pipe. Then you will find two male thread ends. These connect to both your shower heads. Finally there will be a push/pull knob that is operated to control which head gets the water.

My contractor installed a 4 port diverter. The hot and cold are ok, but when I turn the shower on, the flow starts in the hand held shower head and not the main shower head. According to Grohe, whichever...

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. As far as the instructions from manufacture like I said I have not used that particular brand much,so I really couldn't say. Hope this helps some. Thanks

Hot water not working - no shutoff valve in line, and hotwater works at sink.

From what you've described, it's got to be a block between the main supply line and the shower head.

If you have never used this shower after its installation, it's possible that the temperature limit stop is set too low.

Otherwise, either the hot water valve or the balance spool need maintenance. The instructions on pages 4-6 of the link below should be helpful for correcting the problem.

My thermostatic concealed shower valve only gives either boiling hot water or cold water, there is no inbetween temperature? the cold is fed from mains and the hot from a combi boiler. the plumber has said...


If the hot and cold are fitted the wrong way round then the thermostat on the shower unit cannot operate properly!

Most thermostatic mixer showers have a 'bi-metallic' thermostat, if you supply the hot to the cold and vice versa IT WILL NOT WORK.

It is like wearing the left shoe on the right foot and the right on the left! It doesn't work.

Re-install the hot and cold to the correct supply, and this will sort it.

I hope this helps.

Verify the height from the shower valve to the Shower head, the instructions specify the correct distance if it is too short the pressure could be getting up to the shower head.

Perhaps the water pressure it too high at the valve not allowing all the water down the faucet outlet, there are set screws on the sides of the shower valve to adjust the water allowed in the mixing chamber.

Something is restricting the water flow to the faucet, creating enough pressure to send some of the ater supply up to the shower.

I hope some of these ideas help

I have installed an AS 2555.501 Pressure Balance Vave and now the water pressure in the shower is low

this problem happens quite regularly as the valve will reduce the pressure but sometimes it will reduce too much, you can adjust it up, but you havent mentioned which type of shower valve it serves?
as the shower may not be suitable for the plumbing supplies it connects too , & how they are installed?
i am thinking its from the cold water main & that the valve requires storage feed instead of incoming water main supply? possibly thats why you installed a reducing valve??

Let me know?
