the diverter knob is either stripped or the diverter itself itself may be broken turn the water supply off take the knob off a carefully remove the diverter shaft if the flapper is missing look inside the housing for the broken piece then take the name and model down to Home Depot or similar home store and someone will be able to match it up,. but my money is on the stripped knob
showerThe Bath uses a lot more as the tub spout does NOT have a flow restrictor
Bath tubs don't necessarily contain a shower, and a shower may not have a bath tub. Shower tubs are a combination bathtub and shower; the shower head is usually mounted above the bath tub, allowing for bathing and shower drainage.
Gravity. The shower head is probably 4 or 5 feet higher than the bath tap.
Well this is the difference. A bath is in a bath tub and you sit and clean yourself. A shower is standing up in a tub or shower and you clean yourself.
A tub faucet acts as a shower and can be used to bath in the bath tub. It is a pressure valve which makes the flow of water through it constant and gives a nice shower.
In the shower, bath tub or even when you wash your hands.
It can if you put a tub underneath and possibly a spout on the shower control unit.
Is more water comming out your tub spout? if so change spout
they both distribute water
Shower spouts are usually 60 - 70 inches above the tub floor.
Either you don't have the knob pulled all the way, or the disc in the spout is faulty.
A bathroom would have a toilet-sink-tub and or shower. A half bath has a toilet maybe a sink but no tub or shower.
