Did you ever play”I Spy” if you’re a child? It’s a very easy game where you find a nearby object, give someone else a hint to what the thing is, and see if they could guess what you spied along with your small eye.

As homeowners, we play a similar but perhaps not nearly as enjoyable version of the game — attempting to identify home issues before they become big issues.

In regards to catching common plumbing issues such as clogged drain, you can actually use a range of senses including sight, sound, and odor. Here are five signs that you have a blocked drain.

A Toilet, Sink, or Tub Drain is Flowing Slowly (or has ceased completely )

This is about as clear of a indication that you can get that there’s a clog. If it’s just 1 fixture that’s affected, the most likely cause is a blockage from the trap, that is the U-shaped part of the pipe below the drain that retains water to prevent sewer gases from coming up. If you can eliminate or push the blockage past the trap, it should fix the slow drain.

Running Water in the Bathroom Causes the Toilet Bowl to fill with Water

Since the drains of a bathroom are connected at some stage, having one fixture or socket affecting the water level of another generally means there’s a blockage early on in the drain line.

Multiple Drains Are Slow at the Same Time

If most or all of the drains in the home are acting up at once, then it is a symptom that the blockage may be located in the sewer line, that is the underground pipe that carries wastewater out to the municipal sewer system. This sort of blockage should not be ignored or you could wind up having sewage backing up into your home.

Bad Smells

If you see a foul and unexplained odor in your home, it could be caused by a plumbing blockage that hasn’t become visible nonetheless. The blockage could be organic materials that have rotted (common in kitchen countertops ) or the launch of a sewage backup from a blocked sewer line.

Strange Sounds Coming from Pipes

Since the majority of the pipes are concealed, it is great to keep your ears open for signs of a clog. This can be sounds such as dripping, bubbling, hissing, or banging.

What to do Next

The way that you unclog a drain is dependent upon where the blockage is located and its seriousness. For example, if you have a slow drain in just a bathroom or bathtub, you can try out plunging or retrieving the blockage with a bent wire. However, if the blockage seems to be deeper into the plumbing system or is affecting numerous sockets, then you ought to have a professional plumber take a look.

We also advise that you do NOT use gel or liquid drain clears to try to purge any drain. These products have harsh chemicals that can produce toxic fumes and can damage your plumbing.
