If a drain is blocked, could it unblock itself if there is rain or water continuously flows through it?

Answer 1

depends on the blockage

Answer 2

Well first, if a drain is blocked, you wouldn't get any flow through it. So this premise is wrong. Now for other possibilities. If you allowed water to back up above a clog, you might conceivably build enough back pressure (due to the height of the water) to loosen or even free the clog. It is not very likely since you would not get much pressure on the clog this way, but stranger things have happened. Another possibility is the clog was caused by a blocked vent line, and the vent was clogged because of freezing. Then the clog may disappear because the temperature rose enough to melt the vent clog and free the line.

Answer 3

No, if water is moving slowly through it, you could have a partial stoppage, sometimes consisting of things like potato peelings, or rice, or even grease. If you have a vent pipe for that particular drain, there might be something restricting the vent from doing what it is supposed to do. Use a plunger, and maybe that will help, but hold something over one of your basket strainers, to create back pressure while using a plunger on the other side of the sink. Good luck.

Answer 4

properly first, if a drain is blocked, you does no longer get any circulate by it. So this premise is incorrect. Now for different possibilities. in case you allowed water to back up above a clog, you're able to conceivably build sufficient back tension (by way of top of the water) to loosen or perhaps unfastened the clog. it isn't possibly because you does no longer get lots tension on the clog this type, yet stranger issues have occurred. yet another risk is the clog replaced into brought about via a blocked vent line, and the vent replaced into clogged by way of fact of freezing. Then the clog might disappear by way of fact the temperature rose sufficient to soften the vent clog and unfastened the line.

Answer 5

Yes, pressure build up can make the clog go through, but what the clog caught on might still be there.

Unless the clog was a once in a lifetime event, say, a tedy bear as opposed to, say, a long haired showering person, it will be fine.

If the clog was something likely to recur, then you'll have to face it.

Answer 6

yes, your vent pipes are open to rain & if the clog is toward the end of the line the water pressure would be great!
just like when you clear a clogged toilet buy flushing it till the water comes to the top of the rim +/- 6 gallons of water is allmost 50lbs resting on the clogg!
