– One of the most apparent signs of a blocked drain is slow emptying of the sink or tub. The problem typically becomes worse over time. Slow drainage can also occur in the shower and cause water to accumulate on the floor.
– When a blocked drain is present in your plumbing… water, hair and debris continuously accumulate. Stagnant water and decomposing solids have a pungent odour that can spread through the air and be quite noticeable in the area around your sinks, showers, tubs and toilets.
– A locally blocked drain will often cause the affected fixture to gurgle as the water drains. If you have a main sewer drain blockage, you may hear gurgling in your tub or shower when you drain your sink as well.
Changes in Flush
– A blocked drain can make the water levels in your toilet rise higher when you flush, or it could affect filling and lead to lower water levels in the bowls. A main sewer drain blockage can also cause water to flow into the tub or shower when you flush the toilet.
Also be aware of foreign objects in your toilet bowl, patches in your yard that are always wet and/or cracked walkways from sink holes.
