How Do I Determine If My Stormwater Pipes Are Blocked?

There are numerous indicators that your stormwater drain is clogged. Several of them include the following:

Pooling water or boggy areas in your backyard indicate that water is not escaping into the drainage system, indicating a blockage or simply insufficient stormwater drainage.

Once a stormwater drain or pipe becomes clogged, it often overflows. This is because stormwater drains are typically capable of handling a large volume of water. As a result, clogged stormwater pipes can result in a variety of serious problems, including the following:

 Property and environment damage:

A clogged gutter may allow water to enter your home. It is capable of passing through doors and causing damage to your floors.

Mild dangers to health:

Rainwater that collects on the ground may attract additional mosquitoes or promote algae development, which may create a slipping danger. If rain is unable to reach your stormwater drainage system, water may back up onto your roof, resulting in leaks into your house and the possibility of mold development.

As a result, it is essential to take all necessary precautions to avoid a stormwater drain obstruction. This will protect your house from a potential flood and the associated damage.

The Natural Way To unblock stormwater pipe

If your drain is blocked only by soap or fat, you should always attempt to unclog it with boiling water (but be cautious not to burn yourself or melt the sink seal!). If this is ineffective, a good next step is to use natural enzymes, so in the following sequence, pour 1/2 cup salt, 1/2 cup bicarb, 1 cup vinegar, and 1 cup boiling water down the drain. This procedure is completely safe for you, the sink, the pipes, and the environment, and may be performed as many as necessary… but will have limited impact on serious clogs. Alternatively, your local health food shop or pharmacist may sell bacteria-based enzyme cleansers that are as effective and often smell rather nice!

The Time-Honored Method To unblock stormwater pipe

There is no substitute for the good old-fashioned plunger when it comes to forcing the block from the plumbing line. The power of the push propels air through the clog-clearing pipe. 

Cover the overflow with a moist towel before plunging to guarantee a secure drain seal and to drive air out through the drain obstruction. If you have a double kitchen sink, check that the second drain is blocked to maintain proper pressure. Perform this exercise many times before throwing your hands in the air. 

Numerous do-it-yourselfers have noted that this is one of the most effective approaches.

The Technical Route To unblock stormwater pipe
