Re: Bathroom Sink - slow drain

The only thing wrong I can think of is that your waste trap could be clogged with some human debris, like accumulated hair, maybe a cigarette butt or whatever, we don't know. Since you have tried liquid sosa and hot water and it didn't work, perhaps you can try inserting an air hose at the sink drain opening and let pressurized air blow into the narrow waste trap to perhaps push any clogging debris inside to the plastic waste pipe. Try it several times, it might work. 😉 :p

Re: Bathroom Sink - slow drain

Hmnnn... my reply 4 hours ago somehow didn't make it.

That drain cover might be threaded. Try rotating it counter-clockwise. And sometimes the cause of clogging is algae growth. What troubled our sink sometime ago was the growth of black, slimy algae. I just took a tingting from our walis and dislodged all that I can reach. And then washed it all away with water.

For some reason we weren't bothered by it again. And its now more than a year.

Re: Bathroom Sink - slow drain

Some pedestals are lagbolted to the wall, in which case you have to unbolt first,
but usually they aren't really attached to anything. They're not even supposed
to bear the full weight of the sink, which is supposed to be bolted to the wal.

If your bathroom contractor anchored the pedestal's base with white plaster,
you will need to chip/grind/file it away. If portland/pozzolan plaster was used, you
are close to screwed, but you can try anyway. Contractors are supposed to use
white silicone grout for that, but *shrug* old techniques die hard.

After you get the base cleared, what you're supposed to do is get a helper (or
a piece of scrap 2x3 cut to length) to help prop up the sink, just in case its bolts
have lost purchase on the wall: Lift the sink up slightly and prop up, then wiggle
the pedestal carefully out.

That gives you access to the P-trap or U-trap, and a chance at addressing the #1
cause of persistently-blocked sinkdrains: acumulations of human hair, which serves
as a trap for other debris. With the usual bucket underneath to catch wastewater,
use an adjustable wrench or channellock-type pliers to remove the trap and then
clean it out. If the blockage is further down the waste pipe, you can at least use
a drain snake (pleje) to clear it out, since the trap is now out of the way.

You'll need PVC tape for the trap threads, and possibly silicone sealant outside all
plumbing connections, to reinstall. Test for leaks/blockage before reinstalling the
pedestal.

Good luck.

Re: Bathroom Sink - slow drain

Thank you for all the replies.

I figured it could be hair or soap but I could not get to whatever it is because of that sink drain cover 🙁 . If only I can remove that cover and see what is inside that drain.

If I can remove that cover, then may be I can try a few tricks like the walis tingting like joey81 said. If the cover is up there is about less than an inch of space between the cover and the sink and you can barely stick your finger in. I am afraid to use walis tingting at this point because it might break and add to the problem.

The air hose suggestion by rosy might work if only the hose can fit.

After reading what needs to be done to get to the p/u trap... I am thinking that it might be too much for me... basically a newbie. I figured how to remove the p/u trap but to get there is quite a challenge and I do not want to dare playing around with the pedestal base. Thanks horge for the suggestions though. I appreciate the help but with my 'DIY skills' :rolleyes: they are just way over my head.

I tried rotating it counter clock wise but it would not budge. Besides it feels sharp on its edge... may be enough to cut your hand if you hold it so tight and force it to rotate. Plus you do not have that leverage because it does not go that high to give you a good grip at it.

Btw, I checked Google and it showed me the drain cover being sold here in the Philippines at some pinoy websites. I am saying this because I am thinking if it is being sold as a part on its own then there is a way to remove it.

It will help others understand what you're dealing with.

If it's one of these (technically involving a 'stopper' not a 'drain cover'):

you may need to get at the plumbing behind the pedestal to remove it anyway.
The trick ^there is to pull the pivot rod (which pokes through a hole in the
tailpiece pipe, on through a hole or hook at the bottom of the stopper, thus
preventing the stopper's removal), away from the stopper, and this sometimes
means flexing a spring-clip where the rod meets the clevis plate/strap. Other
designs use a tightening screw. You don't need to pull the pivot rod all the
way out of the piping, just back it up enough, so that it no longer retains the
stopper... and you can lift the stopper out of the drain easily.

Here's a labelled diagram, so you can understand the jargon I just used:

No tools required, just strong fingers... and that $%@! pedestal out of your way.
You can actually reach around some pedestal designs and get this done.

With the stopper out, you can try fishing crud out of the trap, but be careful
if you use bent wire-- some traps are cheap plastic, and you can gouge a hole
in them if you get too physical.

To return the stopper, drop it in with its hole/hook aligned with the pivot rod,
and then push the pivot rod back into place so it goes through the stopper's
hole/hook. It may take a few tries, lol. This is not a job for pansies: it takes a
manly disregard for the risk of small cuts in a fairly germ-laden environment.
That said, have some betadine or alcohol on hand for post-repair washing. 🙂

Although all my projects install sinks with them, I personally think stoppers are
a load of bullchips: we wash our hands/faces with running water, not standing
water in a drainless basin (panahon pa ni Rizal ang ganung style, lol).

Re: Bathroom Sink - slow drain

halos ganyan din yung sink namin, pero may space between that pedestal to the wall, mga 7-8 inches na gap so accessible yung p trap... and yung pedestal pwedeng alisin, not bolted nor cemented whatsoever, check mo muna sir then try pulling dahan dahan

good luck!

Re: Bathroom Sink - slow drain

@horge... I am a bit confused between a stopper and cover... my bad. It is not what you showed in the pictures because it does not have a lift rod. I think based on what I found in Google, I have a spring loaded/push button style pop up. The sink is almost similar to this even the faucet is similar to what we have and the stopper/cover that I was talking about looks something like

Re: Bathroom Sink - slow drain

Ooookay...

I've never worked with one EXACTLY like that, but I've dealt with another
push-down/popup stopper before, and this is how I uninstalled it.

Pop the stopper up. It'll only go up by 1/3 to 1/2 inch, but that's enough.
Use a piece of sheet rubber (slingshot band or even a rubber kitchen glove)
to grip the stopper cap, and twist counterclockwise, while pulling up slightly.
Be careful here because the cap will come off with a wide rubber washer
under it, and more importantly, a delicate spring hanging from its center.

DO NOT DROP ANY OF THESE PARTS INTO THE SINK/DRAIN.
SET ASIDE AND CLEAN ELSEWHERE IN A PLASTIC BASIN.

With the cap removed you'll see a threaded metal sleeve upright in the drain
holding another spring and a plastic collet inside with 4 "claws" facing up. Lift
the spring (and any plastic collar if there is one) out and set aside. Now you're
left with the threaded sleeve and the collet. You'll need pliers to GENTLY grip
the threaeded metal sleeve and ease the whole thing counter- clockwise...
'unscrewing' it until it's loose enough for you to keep unscrewing via fingertips,
then lift it out: sleeve and collet together.

DO NOT DROP ANY OF THE PARTS INTO THE DRAIN.
SET ASIDE AND CLEAN ELSEWHERE IN A PLASTIC BASIN.

You'll have clear access down the tailpiece, and the trap below it, using
a piece of wire or an old toothbrush to fish out the gunk/hair.
Reverse the disassembly steps to reassemble.

YMMV.

I only did this once, and on a different-looking push-down, and it was
not a lot of fun. I had no choice however, as I could find no plumber
familiar with the system. I eventually changed the whole drain, from
sink flange down to the P-trap, because I didn't want to have to deal
with so many small parts again, and because the whole design seemed
more clog-prone than a traditional stopper.

Re: Bathroom Sink - slow drain

@horge... hey thanks bro... very informative and detailed. I think I am able to follow your instructions. Let me try it... If I fail... I can always call the building maintenance. 🙂

I will keep you posted.

Thanks again.

Re: Bathroom Sink - slow drain

Finally it is fixed.

I cannot remove the stopper cap based on horge's instructions because the cap is stuck for whatever reason. So I went to get a pop up drain with p-trap and called the building maintenance to do it for me. A little over Php 1000.00 total cost but I think I learned something from it.

So what caused the slow drain? It was all that gunk, black, slimy stuff that obstructed the flow. The pop up drain pipe as I noticed has 2 holes smaller than a Php1.00 coin where water could flow thru. The 2 holes are not easily accessible for cleaning unless you remove the whole pop up assembly. The assembly is not that strong too that if you tighten it too much it may crack.

Next project is to replace the shower valve. I am hoping I can do this myself now. 🙂

Thank you to the members that replied to my posts and guided me on what I need to do. I appreciate the help.

Re: Bathroom Sink - slow drain

Try using a wet/dry vacuum cleaner to remove the clog form your sink. That is if you have one and you were successful in removing the stopper. Just fill the sink with some water, use the blow side of the vacuum cleaner to push water into the clog. Run it for about a minute, then immediately transfer the vacuum hose to the suction side of the vacuum cleaner and run it for another minute. Do this several times to loosen the clog. Most often the clog will be suctioned out after several repetitions. Just make sure that the seal of the vacuum hose to the sink hole is tight. You can just wrap a wet towel around the end of the vacuum hose and push it firmly against the sink to make a tight seal. Be ready to get wet during the blow cycle! I hope this helps.

I have read and read a lot of your posts, great, your article has very good and very useful content, thank you for sharing. temple run
