If your shower is draining slowly you can be sure you have clogged pipes.
Although most people will choose a chemical clog remover as the first method of drain cleaning, it’s a very controversial method.
Some say that these products are harmful to pipes; others say just the opposite.
If there is a serious problem, chemical drain cleaners, will be of little effect.
Because these products may back up into other pipes, they should be used very carefully. A backup into the washing machine or dishwasher would cause a serious problem.
Most plumbers agree that chemical cleaners are rarely effective and are used too frequently by consumers.
Rather than using one of the chemical cleaners, plunging the shower drain might solve the problem.
If your shower is draining slowly and you have not been able to correct the situation, it’s time to call a local professional plumber.
