If you are considering using an off the shelf Bunning's chemical drain cleaner, here are a few points to consider.
A blocked drain usually happens to all homeowners once in their life. The first port of call is to run to the hardware store and grab a chemical drain cleaner. While sometimes this may work, if misused can be dangerous. People who use chemical drain cleaners tend to have no plumbing experience, and this is where hazardous mistakes occur. Chemicals are toxic, and the safer option would be to contact a drain cleaning plumber if you have a blocked drain.
1. The Chemicals are dangerous
Most drain cleaners have sodium hydroxide and sulfuric acid. And, contact with skin can cause irritation and chemical burns.
Fumes emitting from chemical drain cleaners can also damage lungs, eyes and cause difficulty breathing. Plumbers are not doctors, but still, give you the advice to avoid using chemical drain cleaners. A blocked drain plumbers charge is a lot cheaper than a hospital visit.
2. Drain Cleaners Can damage pipes.
Unless you have experience of using chemical drain cleaners, it is quite easy to make mistakes. Chemical cleaners can be a short term fix but not an effective one. Drain cleaning chemicals can erode at galvanised or cast iron pipes, causing leaks, causing water damage. The blockage might be gone, but you can guarantee it will probably re-block. Drain cleaning chemicals are expensive, so it is just as cost-effective to use a drain cleaning plumber.
3. Environmentally Unfriendly.
Experienced plumbers are trained to use machinery to unblock drains that are both safe and clean for the environment. Plumbers do not recommend chemical drain cleaners. Don't think by running off to the hardware store to buy a chemical drain cleaner you are going to save money. A drain cleaning plumber with the right tools can safely make sure that drain blockages never happen again, saving homeowners money in the long run.
