If you are not a qualified plumber, you should avoid tackling more serious plumbing problems as this can lead to further damages and cost you a lot more than fixing the original problem.
However, it is always useful to know what the most common types of plumbing problems are, what causes them, and how they can be prevented.
Clogged sink: this is the most frequently encountered problem that is caused by soap residue, grease, hair, and other foreign objects that clog the drains. The main symptoms of such problem are slow drainage and even water coming back into the sink.
Tub problems: are also almost always caused by a clogged drain and you are likely to see the water drainage stopping completely or slowing down.
Shower problems: if you feel that the temperature of the water fluctuates, then this is likely caused by the thermocouple of your water heater. Other common problems of the water heaters are damaged shut-off valves and corroded pipes.
Toilet problems: if not fixed on time, these are the problems that are likely to cost you the most in water bills. If your toilet flushes, but the water keeps running, then you will have to fix your toilet flush tank and the most common problem there are flush valves that don’t seal properly, refill valve leaks, and float that is too high or too low. Flushing tissue in the toilet can also cause troubles and can result in blocked or slaw drainage.
This advice should be helpful in many problems.
