I don't know how to open the shower. It only works the water below

You may have a very small access panel on the front of the shower pan or through an access point in a cabinet on the backside of the shower wall. I have seen the shower tail piece get cut too short and as a result is becomes disconnected from the "P" trap under the shower.

just turn the water valve down some

Hansgrohe hand showers have filtration sometimes on the inlet side of the hand shower. You must unscrew the smooth conical nut from the handshower to expose the filter and the flow restrictor. If your hand shower is not equipped with a filter gasket, you should use one to protect your hand shower from the particulate.

Filter gaskets can be used at your body sprays and shower head as well if you have them. If you have a Hansgrohe thermostatic valve you don't need the little filter screens, because the valve is filtering the water good enough. We do not recommend opening your handshower for cleaning. There would be a strong chance you may not get it together again, or it may become damaged.

If your concern is with a buildup of lime on the spray faces, you can use a decalcifying agent to dissolve the deposits, but do not soak for more than 10 minutes and then rinse well with clear water.

Take the gasket to your local hardware store and have them match it up.The answer is no, the gasket is not supposed to be split. It was probably tightened too much.

You have to turn main water off to house, then in side shower head is a gasket / otherwise known as a 0-ring, that needs replacing. Yes, a 50 cent part is causing this. If you don't know how to replace shower head 0-ring, just take shower head to any home depot,they will put it inn for you. Just make sure you turn main water line to house off, otherwise real leak. Let me know if helps. Thanks mike

Is the valve being opened all the way? Sometimes the levers crep bend and it is un-noticed until it bumps into someone like you who knows the difference. Good luck and don't use a chair.

certainly indicates that the unit is not holding water (hence not starting on every flush). as you are seeing water in the shower - this is obviously where it is going. It may be that the internal flap (non return valve) is stuck open or damaged. If damaged you can put a new non return valve in your 40mm pipe run where the shower pipe enters the saniflo - about a tenner from most suppliers.

you can check the pipe lines there are normally more thane one way to set the pressure of the water one by the shower knobs 2 by the behind the head in the wall there are some water valves that may need to be opened up or by the water heater there are some valves there one coming off the heater one just on a pipe by the heater they may need to be opened. try that if that doesnt work come back and let us know and see what else you can do to fix it

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.

o you multitask while you wait for the shower to get hot? Brush your teeth? Make the bed? Maybe even pick out your clothes or iron a collar? Many of us do—and don’t know that while we’re feeding the dog or grabbing that second cup of coffee, two-and-a-half gallons of hot water per minute are funneling down the drain. The automatic trickle reduces the flow of the water as soon as it reaches a comfortable 95 degrees. This way your hot water is no longer running down the drain while you’re away from the shower. The automatic trickle allows your showerhead to warm your shower without wasting hot water and tell you (hear) the when your shower is ready. Evolve is the leading manufacturer of this kind of products.
