Blocked drains can be a frustrating problem and cause many inconveniences. Blocked drains can cause unpleasant odors, slow drainage of water, and even sewage backups. You can prevent blocked drains by understanding the causes.

Blocked drains can be caused by many reasons and, if left untreated, can cause costly damage to your home or business. These are the most common reasons for blocked drains, and how you can prevent them.

1. Foreign objects

Blocked drains can be caused by foreign objects like hair, food particles, soap residue and paper products. These materials stick together inside pipes forming a blockage that prevents water flow.

These blockages can be prevented by:

Dispose of cooking oil in the trash and not down the drain
Avoid pouring leftover food debris or coffee grounds into the sink
To prevent hair accumulation, install drain covers in bathtubs, sinks, and shower stalls
Use minimal toilet paper when flushing

2. Tree roots

Tree roots can often be found growing toward cracked pipes and pipe joints, where they can infiltrate the pipe and eventually block it completely.

To prevent tree root intrusion

Hire professionals to properly install pipes so they’re level
Avoid planting trees next to sewer lines

3. Grease buildup

Blockages can be caused by grease buildup. Many people pour hot grease down their kitchen sink since it’s liquid form making it easily escapes from dishes but congeals quickly once it cools off deep inside your pipes causing stubborn clogs.

You can dispose of grease-laden oils and other greasy substances in your kitchen sink by emptying the trash into a garbage bin, rather than pouring it into your kitchen drainage system.

4. Structural damage

Cracked or collapsed pipes due to age, weather or changes in the soil can cause blocked drains. Signs of structural damage of pipes include:

Slow draining water
Multiple blocked fixtures
Mold growth
Foundation cracks

To prevent structural damages:

Regular inspections of your sewer lines with CCTV inspections are recommended so that professional repair companies can detect and correct any problems.

5. Incorrect pipe installation

Bad pipe design or incorrect installation can cause blocked drains. It is possible for large debris to build up in unreliable areas, causing blockages.

Hire professionals to install pipes correctly and make sure they meet all standards.

Conclusion

If left unattended, blocked drains can cause serious problems. Be proactive about preventing blockages by taking preventative measures, hiring professionals for regular maintenance checks, following plumbing code requirements during constructions, placing catch baskets on screen traps in sink an drain shower outlets to capture any debris before it reaches the drainage system. Take care of your pipes today to ensure that they remain clear tomorrow and in years ahead.
