Fixing Kitchen Sink Leak: Sealing Accordion Drain Pipe & Wall Connection

51105 16
Best answers

How can I stop a leak at the kitchen sink drain joint where the accordion pipe inserts into the wall pipe, without calling a plumber?

The proper fix is to remove the accordion pipe, replace the black gasket in the wall connection, and reassemble it correctly; silicone or glue is not a durable solution [#18233655][#18236128][#18236285] Before putting it back, clean and dry the parts well, and if the fit is loose because the accordion is 40 mm while the wall pipe is 50 mm, use the proper reduction/adapter or sealing tape so it fits snugly [#18230643][#18230700] If the gasket is hardened or the pipe is hard to insert, dishwashing liquid can help it slide in, but the joint should still be sealed by the correct gasket, not by roofing or sanitary sealant [#18234143][#18236734] One reply noted that raising the siphon so the accordion pipe sits diagonally instead of horizontally stopped the dripping temporarily, and all siphon nuts should be slightly tightened [#18234294][#18236285] If the gasket cannot realistically be reached and replaced, the consensus was to call a plumber rather than try to glue the socket joint [#18236128][#18236319]

    It is no coincidence that the harmonica is 40 mm in diameter and the pipe in the wall is 50 mm in diameter. You can fold the end of this pipe with an accordion with sealing tape so that it fits snugly into the pipe in the wall. You can also try to make a donation.

    Silicone will do the trick, you just need to thoroughly clean the surfaces and dry them. After applying the silicone, do not release the water for several hours so that the silicone dries well. The drying time depends on the thickness of the layer. If, as you write, the play is small, then silicone, if it is like your friend @ jerry1960 wrote, these are reductions that must be applied. Without undressing and looking at it, it is just a guess.

    I don't think the silicone will last, in my opinion only replacing the black gasket will do the trick.

    Or the gasket has hardened (overgrown with stone) and the author of the topic does not have the strength to push the stub into the drain. Brush the end of the harmonica with dishwashing liquid and try again :-)

    Jesus .... Sculpture in shit is blooming! The socket-socket connection is not glued. I wonder what you will do when changing the siphon? Will you cut? Because you can't break the silicone.

    I don't know, it is possible, although the backlash doesn't seem that big.
    Measure in your hand and measure the diameters of both pipes. As the same, it is the gasket in the drain to be replaced. If it is impossible to replace, the plumber will help.
    Don't think about gluing it at all. It's a waste of money and time, because it will open anyway. Replacing the gasket on the flare will help permanently.

    Exactly! This type of case is handled in the simplest way, i.e. making it as predicted by the manufacturer with the use of the right quality elements.

    Only the access there is so difficult that I would rather not be able to pick it out :(

    There is no "I can't do it" option. This gasket is already thrown away, so any method of gouging it out is possible.
    betmari wrote:

    In general, I picked up the siphon, because it was somehow low and the accordion pipe was quite horizontal. Now it goes diagonally and it has stopped dripping, so I still haven't pulled it out yet.

    It is also possible and you did it correctly. Only all the nuts in this siphon must be slightly tightened (tightened).

    And what do you think about sealing with something like this: https://archiwum.allegro.pl/oferta/penosil-si...karski-bitum-sealant-penosil-i6882374496.html - the packaging says that it also sticks to wet surfaces

    This is glass wiping. And your siphon doesn't look like a roof at all.

    If you can't pick out the gasket, how would you like to make the seal with some silicone or other g ..?
    I would bet the gasket seized and leaks. If so, you'd have to take it out, clean the groove and gasket, and put everything on something slippery.
    Take a picture of that pipe in the wall.

    This accordion part may not end up inside the pipe.
    However, if you do not like my advice, then do it yourself. There is no obligation to apply them, and there is no criminal liability for ignoring them.

    The one that is in the wall, you can only see the opening itself, and at an angle, so that its edge is partially in the wall, and all this is behind the cupboard under the sink, so you would have to climb into the cupboard :P

    Seriously? And I thought that siphon was somewhere in the living room.

    I do not understand? After all, it is just now that the harmonica goes into the one in the wall. Of course, only this smooth part of the accordion pipe is inserted into the pipe in the wall

    So it's okay, I misunderstood your text.

    1. Photo of what is in the cupboard.
    2. It is possible to climb into each standing cabinet.
    3.The quickest, surest and easiest seal is the easiest way.
    Unless you want to forcefully accept your idea.

    A specialized roofing sealant, about PLN 20 works with water, seals and never dries up.

Topic summary

✨ A user reported a leak in the kitchen sink's drain pipe, specifically at the joint between an accordion drain pipe and the wall connection. Various suggestions were made regarding sealing methods, including the use of silicone sealant, butaprene for better adhesion, and specialized roofing sealants that can adhere to wet surfaces. Some responses emphasized the importance of replacing the gasket rather than relying on sealants, as silicone may not provide a long-term solution. The user expressed difficulty accessing the joint due to its location behind a cupboard. Ultimately, the discussion highlighted the need for proper sealing techniques and the potential necessity of professional assistance if the gasket cannot be replaced.

FAQ

TL;DR: Most kitchen sink leaks happen at the 40 mm-to-50 mm slip joint; "the harmonica is 40 mm … wall pipe is 50 mm." Clean, reseat, and fit a proper reducer or sealing tape for a tight, drip‑free connection. For DIYers fixing the sink-to-wall leak today. [Elektroda, jerry1960, post #18230643]

Why it matters: You’ll stop the drip fast, avoid damage, and keep the drain serviceable.

Quick Facts

How do I fix a kitchen sink leak where the accordion drain meets the wall?

Measure both diameters. If they match, the wall gasket is worn. Replace that gasket on the flared drain connection. Do not glue this joint, or you will lose serviceability later. “The socket-socket connection is not glued.” [Elektroda, telecaster1951, post #18236128]

What size reducer or gasket do I need for a 40 mm hose into a 50 mm wall pipe?

This joint is typically 40 mm (hose) to 50 mm (wall). Fit a 50×40 reducer or a matching rubber gasket. As a temporary option, wrap sealing tape on the 40 mm end for a snug fit. “The harmonica is 40 mm … wall pipe is 50 mm.” [Elektroda, jerry1960, post #18230643]

Will silicone sealant stick to polypropylene sink pipes?

Yes, for small gaps, if surfaces are cleaned and dried well. After applying, avoid water for several hours to cure. Thicker beads need longer. “Silicone will do the trick” when prep is right. Use it as a stopgap, not instead of the gasket. [Elektroda, mariuszp19, post #18230700]

Can I prime with butaprene or glue the joint to stop leaks?

Avoid primers and glues on this joint. It must remain disassemblable for future service. Replace the wall gasket instead of bonding parts. Gluing may force you to cut the drain later. [Elektroda, telecaster1951, post #18236128]

Is roofing bitumen/silicone sealant (e.g., Penosil) OK on sink drains?

No. Roofing sealants are for roofs, remain tacky, and complicate disassembly. Use the correct sanitary gasket or reducer. As one pro put it, “This is glass wiping. And your siphon doesn’t look like a roof at all.” [Elektroda, retrofood, post #18236285]

I raised the siphon and the drip stopped—did I fix it?

Changing the angle can reduce pooling and stop a minor seep. However, the underlying seal can still be weak. Inspect the wall gasket and reseat the connection. Retest under full flow. [Elektroda, Anonymous, post #18234294]

How long should I wait after applying silicone before using the sink?

Do not run water for several hours after application. Cure time depends on bead thickness. Let it fully polymerize before testing. [Elektroda, mariuszp19, post #18230700]

How do I replace the wall spigot gasket with tight access?

Use the designed method. “There is no ‘I can’t do it’ option.”
  1. Pull out the 40 mm tailpiece from the wall socket.
  2. Gouge out and discard the hardened black gasket; clean the groove.
  3. Insert a new gasket, reseat the tailpiece, then lightly tighten the nuts. [Elektroda, retrofood, post #18236285]

What lubricant helps the stub slide into a tight gasket?

Use dishwashing liquid on the end of the tailpiece. It eases insertion without harming the rubber. “Brush the end of the harmonica with dishwashing liquid and try again.” [Elektroda, Lisek64, post #18234143]

Do I need to retighten siphon nuts after adjusting the angle?

Yes. After repositioning, snug all siphon nuts to prevent weeping. Avoid overtightening. “All the nuts in this siphon must be slightly tightened.” [Elektroda, retrofood, post #18236285]

Is wrapping sealing tape a permanent fix?

Treat tape as a stopgap to snug a 40 mm tail in a 50 mm socket. The durable repair is a new wall gasket. “Replacing the gasket on the flare will help permanently.” [Elektroda, telecaster1951, post #18236128]

Access is tight—should I still attempt this or call a plumber?

You can reach it. “It is possible to climb into each standing cabinet.” Use the quickest, surest fix: replace the gasket or reducer. If you cannot extract the old gasket, call a plumber. [Elektroda, palmus, post #18236697]
