How To Fix (and How Not To Fix) a Blocked Drain

Published by Point Loma Electric, Plumbing, Heating & Air

It’s an all-too-familiar tale: First, water starts going down the drain slower than normal. Then it barely seems to be draining at all. Before long, water pools up and won’t budge in the slightest. It’s a blocked drain, and anyone will agree that it can’t get fixed a moment too soon. 

So in the interest of solving the problem as quickly as possible, many people reach for the first available option. Unfortunately, this doesn’t always turn out to be the best one – or even close to it. That’s why this article will go over three different methods frequently used for clearing drains, two of which are highly effective and one of which does more harm to the plumbing system than good.

Drain Augers (aka Drain Snakes)

One popular method for clearing drains is the auger or snake. This durable, flexible metal coil ends at one end in a portion of wire resembling a corkscrew. This end of the coil is sent down the affected drain to drill into the blockage, either breaking it apart or “hooking” it so that one can pull it out. 

Drain snakes come in varying lengths and can be fed into the drain by hand or with an electric motor. They are commonly used by plumbers and DIY’ers alike. However, a drain snake can scratch porcelain fixtures in untrained hands and severely damage pipes made from less durable materials. When performed by a pro, snaking is a safe and effective way to clear blocked drains and even clean the pipe walls to some degree.

Hydro-Jetting Machine

Another great method for unclogging drains is hydro-jetting, which involves using a special kind of high-powered pressure washer. The operator of this machine feeds the water hose into the drain. The hose nozzle sprays a powerful jet stream straight ahead to blast away obstructions while several smaller jets spray behind the nozzle at an angle, helping to propel the hose forward.

Once the blockage has been broken up and washed away, the operator pulls the hose back up while the rear-facing jets spray the pipe walls once again to remove any leftover residue or grimy buildup. Hydro-jetting is used for both fixing stubborn clogs and routine drain cleaning. Due to the extremely high water pressure involved and the equipment’s specialized (and expensive) nature, this is another drain clearing method best left to the pros.

Chemical Drain Cleaners

The final method on this list is very popular among homeowners due to its accessibility, affordability, and relatively easy application – chemical drain cleaners. These products, sold in most hardware stores and supermarkets, contain harsh chemicals which react to the water and organic matter in a drainpipe to generate heat and dissolve the clog.

Unfortunately, the pipes themselves are not immune to this chemical reaction and may get damaged in the process. It’s also not uncommon for these products to “scar” fixtures like sinks and tubs. In addition, they can produce toxic gases, cause severe burns, and be fatal if swallowed, so great care must be taken when using them. In general, the risks involved in using chemical drain cleaners are not worth the rewards.

I am very pleased with this company because they have great people working for them. [My technician] was organized and all were at the house in 2 days. Paper booties were worn. The electricians knew what they were doing and produce excellent work. I had 3 new circuits put in along with updating box. All this was done in one day. This co also sends a pix of technician who is coming to your house. Every person had lovely manners, and cleaned up, even vacuumed under stove when it was moved. A fine experience and I’d use them again.

I had a water leak at my house and its cause was extremely difficult to find. Our tech spent a long time carefully analyzing and testing all possible options until he found the cause of the leak, like really a true detective, that nobody else before him was able to find. He demonstrated not only that he is a truly top professional but the he also is kind, patient and understanding. He explained all the issues very well and was also mindful of my time and convenience. He works very fast, efficiently and reliably and is extremely nice human being.

Point Loma Electric and Plumbing did electrical work in our house once and we liked the service the first time so we called them again. The technicians have been nothing but friendly and professional both times. They walked us through every step of the process. They showed up on time and completed the work in a timely manner. If we had any concerns they made sure the address them, if anything was needed, they handled it. We will definitely use Point Loma Electric and Plumbing again. Johnny who oversaw the work is the best!! Thank you

Had an emergency water heater leak. Called Point Loma. Within the hour, James shows up and goes to work. And by the next day, we have a tankless water heater up and running. Thanks to James for the excellent customer attention, service and hard work!

Always great to work with them - years 2011 for new electrical panel, and 2025 for some minor upgrades. Erich and Leo corrected 3 problems with old wiring we were having. Very great team and very much appreciate their work.

My a/c has not been working for some time. I called Point Loma Electrical and they sent Nicholas Mullins to stop by and check it out. What a great guy. He was very respectful, honest, evaluated the situation and made recommendations that I felt were straight forward. This company is top notch and I would recommend them to any of my friends and family. This is now my go to ac repair company.

We had Point Loma Elec rewire our entire 62 year-old house's electric. They worked efficiently and were thorough letting us know what was discovered and done each day. Timely, neat, and responsive and affordable with great financing. Highly recommend.

This is a great team. I had to replace some fluorescent lights in the kitchen. I couldn't do it myself because the ballasts had to be replaced and that's above my skill level. Anthony and Matt came today and put in new led lights (with a 10 year warranty- fluorescent lights are ancient tech). Anthony and Matt were very professional and efficient. I would recommend them highly!
