Sewer
drain problems are usually indicated by your toilet or shower drains.
Such an issue should not be ignored or delayed, considering that the
water in your plumbing system does not have anywhere else to go, it
will ultimately find its way to any other plumbing fixture in your
house.
How
will you know if you have a drain problem? One of the sure signs is a
foul odour coming from your bathroom or from the drains, which means
that something is blocking the flow of the drain line. Bigger sewer
drain problems usually begin manifesting itself in the toilet, which
has the most direct line to the sewer. Also, you might notice that
your shower or tub drains won’t begin to work the way they should,
since these two fixtures sit lower than a sink drain.
