This evening, suddenly found the water in the kitchen sink flowing very, very slowly. I contacted a few plumbers and sent video, they quote between rm250 to rm380 if it is a simple and straightforward issue.

Before I get there, anything that I can try?

I’ve never faced this issue before.

I’m considering getting a plunger and some Mr Muscle declogger liquid (not sure how safe and useful is this). Worth a shot? Anything else that can be tried?

We don’t knowingly pour down cooking oil or things like that down the sink. But it’s been 5+ years, not surprised it can get clogged from normal everyday use.

By the way, to add, I believe the clog is near the surface. Cause even after letting the water fully recede and waiting for an hour, just turning the tap on for 5 seconds results in the water clog being visible coming out of the sink hole.

Get a garden hose, make sure high pressure a bit not budak kencing power, unscrew your sink exit pipe underneath nearest the wall and put the hose down the outlet. Turn on water and flush out debris. Expect a lot of dirty water to splash back when you unscrew the outlet have a water basin on standby.

Anything that doesn’t involve unscrewing the underneath of the sink? Cause got knows I’ll just make the matter worse potentially.

plumber actually tackling the root cause and check whether you will need a pipe replacement.

yes you would need to open up the down pipes to check what is the issue.

• buy drain rod
• buy drain snake

pick which one is suitable for you. You want to save money you gotta get your hands dirty else just pay up for the convenience. They'll most likely be using the tools I mention as using chemicals to declog is waaaay slower. Do work for 20 mins ask you to pay RM300

The Mr Muscle solution or plunger doesn't work that means?

Cheapest and easiest. Plumbers do the same.

Didn't work for me. Drain snake from DIY only RM21 and I can reuse for decades to come while Mr cleaner 1 bottle what? RM10? Single use

Bought a chemical from hardware store would help

buy the acid type from shopee. rmber wear mask . the smell really strong

means the clog is too heavy ed apa lagi

you think years of clog can remove so easy? like many others said ed, either you pay that RM300 to be clean and get someone else to be dirty

OR

you do the dirty work, and dig the shit inside the pipes out, elbow grease style. its gonna be enlightening when you DIY

Have you cleared the bottle trap below the sink first?

Clear the bottle trap first

Then if possible get the flexible drain clog remover (can buy from hardware shop) to remove all those dirt inside the pipe.

If you dont know what you should do then pay others to do it.

Usually check the traps first and see if it is blocked. If nothing there, can try test drainage of any pipes nearby to see if blockage is only on the sink. If only sink and nothing on traps, maybe you flush something down and it become stuck or the years of pouring cooking oil into the sink have resulted in a massive hardening of oil clump in the pipe which could only be clear with high pressure cleaning.

No I've not tried it, but nobody is recommending pouring some Mr Muscle declogging liquid, or using a plunger.

SO my question is, why? Are those things not gonna work?

It's a kitchen sink, at best there are food scraps and related items in there. There can't be anything big flushed in there, since there is a cover on the sinkhole anyways. No pouring of cooking oil either, but yes cooked food that's on the plates or other cooking utensils get washed down while washing them.

Will a declogger liquid also clear the bottle trap? Assuming that anything in there is going to be food-related (i.e. organic) waste?

drain snake is more effective to me

Try the commercial declogger used by shoplots...

but carefull can melt your flesh to the bone,

better get nitrile gloves when handling these products.,

Then put a pail under your sink trap and open it to see if thats the main reason it was clogged. Run the tap to test while you are at it.

Do you use hand soap at the sink too? Hand/bath liquid soap will cause the accumulation of black colored gel like that will block the water flow as well. You will see if you have them when you open the trap to check.

Small punya hal. Go to MR DIY, buy 1set Snake chain tool (Super dredging tool). Don't buy expensive one. Bcos you won't sakit hati if you want to throw it after used.

careful with those chemical TS,. u dont want to be making chlorine gas inside your house.,..

because plunger or those declogging liquid dont work for known heavy clogs. go ahead and try it then, why asking the dumb question here instead of trying those first?

i tried these 2 already. plunger i already have. Mr Muscle i regret buying since cannot fix and wasted RM9-10-11 when snake RM21 kautim everything. u think i really want to spend RM21 if plunger + liquid solve the issue?

like giftfre said, u can throw away if u don't want to wash and dry it for reuse

Check the bottle trap first. Just take a pail put under the bottle and unscrew it. After long time of usage the organic will clump together. Put declog only going to the surface.

hope this help

U condo or landed ?
Landed sink, sometimes maybe got animal masuk tat water pipe hole?

declogger liquid or baking soda unlikely to work on those hardened stuff (already hardened over the years from your food waste) in the pipes.

I managed to get things going. I plunged for quite a while. Poured some powder stuff in there too.

got some powder selling at shopee... pour in wait few minute then flash water.settle... if not settle pun only few linggit jer

i'll let you know if the acid from shopee works.

bought it recently, have yet to receive it.

My plumber advised against chemical. Health hazzard one thing. Another u could be fucking things up further down the line creatung more issues. Not all piping can tahan those chemical.

Also dont get indon newbie plumber, they will just jolok and use plunger force the fuck out of everything without checking root cause. Most of the time they got no plubming knowledge, their best trait is willing to go dirty do stuff for u. Dont expect them to provide professional advice.

U really need to get ur hand dirty if u want to save $$$. I wouldnt bother with this and spend rm300. The amount is not big, even if u minimum wages also its like 1/5 ur salary. Thats why very important to save up emergency fund. Dont go YOLO BNPL evrything. Just make sure u hired proper plumber.

Malaysia is really one crazy country. Too many dumb dumb that cannoy weight their options.

chemical is ok as long as you follow as per instruction...

of course plumber dun like it as they get less business if everyone use them.

hot water 60-70deg down the drain, not boiling as it might damage the pipes. they will melt any fatberg in the pipes.
vinegar sometimes can help, but chemical is better as it is stronger can disolve the hair and gunk better.

drain snake is good, no jolok with thick plunger as sometimes the excessive force can cause damage.

if got baby wipes, hair and oil stuck long way down the pipes, only plumber can help. last time got relative come and stay a few days, after they cabut few weeks later got blockage in pipes and toilet as well. Tried all but not working. Seems like something outside the house got clogged, plumber say wet wipes, show photo of the gunk as proof. conclusion someone in that group must have flush wipes down the toilet since got toddler.

buy the solution from the hardware store, one bottle I think around RM25-30

Alternative to Mr Muscle which is quite exp.

Get this and unclog it every month. Make sure to use warm to hot water. It works very well for me.

If still flowing even a little, get that enzyme thing at diy. very cheap and it works.

if completely blocked then no choice, need to use snake.

declogger liquid clears up blockage inside the pipe, but that's also assuming the clog is not severe.
The bottle trap catches debris to ensure it does not go down the drain pipe. When your sink clogged, the first and easiest troubleshooting you do is to open up the bottle trap and pour away the content, then clean out any object that is stuck inside.
All you need is a bucket and glove. Just turn the slip nut and remove the bottle.

Even if you don't pour cooking oil, it can accumulate in the pipes from normal washing and become a plug.
Pouring a drain unclogger is the usual thing to do, or use lye (soda panas). Have to follow the instructions carefully, usually its to pour it in and wait 5-15mins and then follow up with hot water. The water mustn't be too hot because the usual pvc pipes are not rated for temps above 60C. Depending on how your pipes are done, you may need a long hose to pour the unclogger/lye solution so that it doesn't just sit in the wrong place and may potentially cause leaks.

Using a drain plunger carefully if you're in an apartment because the pressure might cause leaks downstairs. Don't use a high pressure air drain gun or drain blaster type devices, it caused the access cap downstairs to break and dump water when my plumber did it.
