Our hand held shower head does not stay in a straight downpour position. When the head is put back onto the bracket, the head turns either towards the wall or the shower curtain. The coil is stainless steel covered with plastic. We've tried twisting the coil but it still doesn't point downwards.

Probably it is due to a losen hand shower holder. You need to take it out and fasten it.

Something is clogged - take them all out and snake them out.

you really can not because of the overhead piping holds lots of water and so does this big head....that is just normal for these things...i am a licensed plumber for over 34 years and have done these...its just draining out all the overhead water....

It sound as if the hose end is no longer crimped onto the hose nut fitting. You need a new hose. If you have the purchase reciept call Hansgrohe and they can replace it under warranty if you qualify.

im sure that home depot or lowes (worst case you will have to go to a local plumbing supplier) will have one (by another brand) that will do the trick. you should bring the shower head/hardware w/you to make sure but culligan does not sell the part seperately. (bums) hope this helps but if you need anything else just ask:)

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.

Have you checked to see if the hose was put on backward? Some hoses have backflow preventers on them and it wont work if they are on backward.

Probably the fitting is not working properly. Please change the fitting.

you have to take the handle off
there should be an insert that you can adjust by pulling out and turning
