How do you use Caustic soda to stop your sink from plugging up?

[craigslittleangel]

I've had these for ages, and read on a post on MN, someone using them regularly to keep pipes clear. So, how much do I use? Do I just pore it down the sink and wait? Do I use anything else with it? How often should I use it?

Thanks

I just done this yesterday, mix 100g with 1l cold water and mix and pour down sink and just leave. dont pour down neat and then run water as they harden its important to add them to water and not add water to them. They are very very poisonus so I mix outside in a small bucket I keep in garage and use a stick to mix them. I tend to do it every few months or less often just a couple of times a year when I think the sinks are draining slow.

this bunged sink, does anyone put cooking fat down it?

no I pour fat into a cup and flush down the toilet.

ah

it will slowly block the soil pipe then which the sink waste will eventually join.

If you pour it into an old tin can, you can put it in the bin (or, if solid, out for the birds)

cooking fat

surely no worse than poo

eww just read your link, wow, i flush alot of sloppy food waste down the toilet, gravey, soups etc.

"no I pour fat into a cup and flush down the toilet."

You shouldn't do that. If it will solidify, just pour it into an old tin can or disposable container, put it into the fridge to solidify and then throw into the bin. If it is cooking oil, pour it into a disposable conatiner and put some kitchen towel in to soak up the oil, then throw into the bin.

Cooking fat should not enter the waste water system.
