The water will not hold in the tank and the water is constantly dripping from the tall column on the left(sorry I don’t know official name). Thanks for help.
Tall col. on left is ballcock. Sounds like your flapper is leaking and makin your ballcock run to replace water. Put some egg dye in tank and see if it leaks in the bowl ,if so replace and if ballcock still runs try to ajust are put in new one. Let me know what it is.
