Exactly… that was constantly on my mind. Last time I hired a plumber to fix a leak while I was away, the plumber was incompetent. Did not find the leak (which was in /exposed/ pipework), charged 200 cash and ran with the money. The plumber actually charged 4 times as much as I paid a doctor to make a house call.
Some plumbers can legally buy sulfuric acid for this purpose. So in fact by law I was essentially being forced to hire a plumber, in effect.
My way of thinking is that I’m going to learn something & my tooling costs will be less than a plumber. I’ll “own” the problem for the next time. This one about drove me to the edge, considering I was about to experiment with borderline parasites.
A pro would have had an expensive snake cam… so there’s that. I would not want to put my own snake cam down the pipe because it’s not made for such filthy environments… would likely ruin the cam.
I blame whatever plumber installed the drain. They used many hard-right 90° fittings that hinder snakes. Then they installed no clean-out. And no vent. I also suspect the pipes under the floor may be goffred (accordian-like). So the lesson here is that snakes are not always the answer if the pipes are lousy.
Where do you live that sulfuric acid is illegal?! It’s a basic chemical, I use it all the time. Tried some last night in an ultrasonic cleaner last night. (Didn’t work for that project. 🤷🏻♂️) You can go to the auto store and get a 5-gallon bucket.
And talk about environmentally neutral, doesn’t get much better. I forget the chemistry term, but it “dilutes” in water instantly. That is to say, it ain’t sulfuric acid anymore. When I’m working with it, I just leave the tap running in case of a spill. Or, just throw baking soda on it, receive water and carbon dioxide.
Most of mine comes from draining old car batteries. If I have to give the battery back for proper recycling and get my $10 back, I’m keeping the acid. What if you do that? Illegal to buy, own or both?
I think it’s like this in all of Europe. I know in the US you can get 32 oz. of it at Menards for $8. But that’s not an option here. I have no idea what people do if they need to build a battery. The stuff I got would be different than what’s in batteries. Probably the battery acid is more pure. What they sell to pro plumbers is a bottle labelled as /drain cleaner/ with sulfuric acid as a main active ingredient. It likely has a cocktail of additives to optimize it for drain pipe usage or perhaps make it inconvenient for other usages.
What if you do that? Illegal to buy, own or both?
I doubt it’s a possession offense. They are controlling the sales. If you go to a pro plumbing shop and try to buy it, they will require proof that you’re buying on behalf of a company that was constituted for the purpose of plumbing.
I subscribe to a Youtube channel of a guy who does nothing but clean drains with a pressure washer setup and have looked at doing similar work on my own house and it’s actually pretty reasonable (like $120). I’m sure OP spent more in time and money than that and could have possibly damage their plumbing with the chemical cocktails.
From watching enough videos, OP’s clog may have been from wipes, sanitary products, roots, grease/fat, or a broken pipe. Almost none of these can be fixed with chemicals.
It’s a kitchen drain but not like in the US. Garbage disposals are banned here. So there would be no way for wipes, qtips, or anything bigger than a pea to enter the drain. It’s a terraced house in a dense city, so no trees, which likely rules out roots.
The city water is /very/ hard, and past residents likely put plenty of oil down the drain. Every time the drain regurgitates something, it’s a stinky white substance that appears to have coffee grounds embedded in it. I know not to put oil or coffee down the drain but past residents are another story. So I think a mass of fat, coffee, and minerals from the hard water could be culprits.
WRT using a pressure washer, I think that would be an option if there were a cleanout with a straight shot. That youtuber would probably be paralyzed when coming into a ridiculous series of tight 90s and no cleanout or vent, and possibly goffred pipes. Or does he have some kind of special extra flexible high pressure hose?
The drain infrastructure in most US cities is relatively modern. The city drain pipes are big & thus able to handle a big amount of food waste coming from residents. I think I heard some minority of US cities also ban garbage disposals because for whatever reason their pipework can’t handle the load.
Old cities have small pipes that could not sustain the onslaught of thick food waste, as I understand it. In my city, rats outnumber humans by 2 to 1 and I think they thrive in the sewer. So I’m not sure if it’s also an effort to not feed rats. In any case, the city’s preferred way of dealing with waste food is to put it in the trash.
Recently they required food waste to be separated into a different color bag than the others. So they collect the food waste together and compost it. In the end, this is probably the most forward-thinking approach despite the sewer system being quite behind.
Thanks! That makes sense. I’m American, so our sewers aren’t nearly as old as other parts of the world. Plus, people like me aren’t even on a sewer system. If I want to jam out my septic system, and pay for it to be cleaned more frequently, that’s on me.
