What Is the pH of Drain Cleaner?

last year

Hey everyone, I have a question about drain cleaners. What is their pH level? Are they acidic or alkaline?

Also, how does the pH affect their effectiveness in unclogging drains? Which type is safer and more effective for home use?

Looking forward to your answers. Thanks!

This is the Australia Houzz site, and your profile says a professional in the US. Therefore one would think you know the answer of your question already. I don’t know whether your products are the same as ours, but I will play the game.

Hey there!

Great question! Drain cleaners can be acidic (pH 1-3) or alkaline (pH 12-14). Acidic cleaners are great for tough clogs but can be harsh on pipes. Alkaline cleaners, on the other hand, are generally safer for your plumbing and work by breaking down grease and fats.

While both types can be effective, alkaline cleaners are usually safer for your pipes. Just be sure to follow the instructions carefully!

Hope this helps!

Are farmhouse sinks overrated?
Q

We have four farmhouse style sinks in two different houses, and all present the same problem. It doesn't have anything to do with the material as two sinks are concrete, one stainless steel, and one composite stone. With the two kitchen sinks it's very frustrating spraying out the food particles from corner to corner. Food particles go from one side to the other, and it's very difficult to corral them to the drain. The two concrete bathroom sinks don't have enough slope, so when shaving and brushing teeth, the water and material flow to the opposite side of the sink. It's annoying to wash a 3' wide sink every time it's used. And gross if the sink isn't cleaned from side to side after every use. As a compromise, we're installing a farmhouse concrete bathroom sink with two drains and more slope. As I evaluate many things in life, a, farmhouse sink is a solutions looking for problem.

Hi, probably too late to comment now as you've already gone with someone on this project. Along the wall is the most common solution as it is easier to create falls, particularly if you have large format tiles. You will get water out of the shower given this is a just a freestanding panel, and it will also be cold in winter (speaking from experience) without a door on it. In the Australian Standards you are required to have a 'water stop' or step down to at least 5mm - most people don't do this and this is where problems can start from a waterproofing point of view. Good luck - hope it goes well

Strange smell from either the laundry or kitchen

Laundry drains can really pong when they're seldom used - the water in the trap can disappear and you get a vile sewer smell. Before going to expensive and highly caustic chemicals try 1 cup of bicarb of soda and half a litre of white vinegar down Let it sit for an hour then follow up by pouring boiling water down the sink and see if that helps - you can do it a couple of times - I do mine every few weeks (kitchen and laundry). You could also run your washing machine (empty) on the hottest possible was with a good amount of bleach in it to help. If it's the rangehood - don't be surprised so many people forget to clean them - pull out the filters and wash them (mine go into the bottom rack of the dishwasher on the highest temperature setting).

MB Design & Drafting, I have to contradict your comment about having only 1 floor waste, we have a large double shower with only 1 floor waste, ours is in the centre of our double shower, our tiles are black and by the time we get out of the shower the water on our shower floor is gone, I always clean the tiles and glass before leaving the shower, I leave the fan on while we dry and by the time we are dried our shower floor is almost dry, we have no trouble at all with only 1 floor waste.. Barbara, we have the same problem, which is not a problem at all, my husband likes his shower much hotter than me but we have our showers turned on to suit each other, we have a small seat at each end to sit on while we wash our hair and feet and each others backs.

Drain cleaners usually have extreme pH levels and are most often alkaline, with a pH around 12–14, though some are acidic with a pH as low as 0–2. The pH determines how they work—alkaline cleaners break down grease, hair, and soap through a process called Saponification, making them ideal for common household clogs, while acidic cleaners are stronger and can dissolve tougher blockages like mineral buildup but come with higher risk. For home use, alkaline cleaners are generally safer and effective for everyday problems, while acidic ones should be used with caution due to their corrosive nature.
