Your toilet can get plugged up, or it could be that it is constantly running, or it could even be leaking. These are the main problems many people face with home Plumbers in Rockville Centre. They are fairly common and easy to repair.
Two things that could be the cause of the toilet running constantly are you either need to change the flapper or adjust the float. To change your flapper you will need to turn off the water to your tank and flush the toilet; once this is done you can easily remove the flapper from the chain and where it sets at the bottom of the toilet bowl. Now you can install the new flapper and hook it back to the chain.
If you find that after replacing the flapper that your toilet is still running then you may need to adjust your float as the water is running into the overflow tube. All you need to do is locate the adjustment screw that is found at the top of the fill valve, until your water stops flowing. The water level should be around one inch below the top of the overflow tube.
For clogged toilets all you need is a plunger and possibly a drain snake. If plunging by itself will not work to get that clog out then you may need to get yourself some sort of drain snake. Drill snakes are the best for a job like this. You simply feed the snake all the way into the toilet drain letting it drill through whatever is clogging the toilet and break it up allowing you to plunge and flush the toilet until the clog is gone.
