How To Clear Your Drain

Plungers are often the easiest way to clear a clog. Hot water can also help with some clogs if they’re caused by congealed fats, which would be liquid at a higher temperature. 

Caustic liquid plumbers, which could clear clogs, can also damage your plumbing or make your clog bigger by breaking material loose from the walls of your pipes, so they’re a poor choice in most cases. 

Ultimately, any clog that resists gentle prodding and hot water is best left to professionals who can remove it completely and safely, like our team.

How can I prevent clogs in my business’s drains?

Be mindful of what goes into your drains, clean them with enzymatic cleaners, and run enough water along anything that passes into a drain to carry it through to the sewer. Taking these steps can lower the risk of creating clogs in your plumbing system.

Can hard water cause clogs?

Yes, untreated hard water can lead to slow drains and frequent clogs by allowing sediment to accumulate inside your pipes and narrow them.

What causes drain backflow?

There are two possible causes of backflow: a clog somewhere in your drainage, which causes water to find an alternate route up another drain, or high pressure in your lawn combined with a gap in your sewer, allowing water to push into your pipes.
