Preparation for work

Surely everyone faced the problem of ineffective drainage of water from a washbasin, sink or bath. The reason for the clogging of the siphon, which serves as a kind of water seal, preventing sewer gases from entering the room where the above plumbing fixtures are installed, can be anything: soap, dirt, food debris, hair that partially settles in the siphon, over time making it difficult to drain water.

Preparation for work

No special tool is required to clean the siphon. Required minimum:

• old toothbrush;
• rags;
• sealant or silicone;
• bucket or other container.

We provide access to the siphon.

Advice: for the convenience of performing work, it is advisable to place a rag under the siphon or put a container to drain the residual water.

We unscrew the upper siphon fastening nut.

Tip: remember the position of the siphon in relation to the discharge pipe, this will facilitate reassembly.

We pull off the siphon from the drain pipe.

Remove the O-ring and nut.

We unscrew the nut securing the discharge pipe.

Disconnect the pipe from the siphon.

We disassemble the siphon by unscrewing the bottom cover.

Using an old toothbrush, clean the inside of the siphon and lid.

We wash the cleaned parts under running water.

Tip: it is advisable to flush over a bucket, the contents of which should be poured into the toilet after the end of work. This will avoid clogging the siphons of other plumbing fixtures.

We wash the O-ring.

We clean the drain pipe with an old toothbrush and rinse it with running water, after placing a bucket under the pipe.

We clean the old sealant from the outlet pipe.

We clean the inner surface of the outlet pipe with an old toothbrush.

We wipe the outer surface of the drain pipe with a rag.

We assemble the siphon by screwing the bottom cover onto it without much effort.

We put a nut and an O-ring on the drain pipe.

We bait the siphon, securing it with a nut for several turns.

Apply sealant to the tapered surface of the outlet pipe.

Note: in this case, the connection of the discharge pipe to the siphon is made without a rubber seal. Therefore, a sealant is used to improve the connection. It is not necessary to use a sealant with a rubber seal.

We attach the siphon to the outlet.

We tighten the nut securing the outlet pipe to the siphon until it stops, with little effort.

We expose the position of the siphon relative to the drain pipe. We tighten the top nut with a little effort.

We open the tap in the sink and check the tightness of the siphon assembly.

The water is instantly drained from the sink without lingering in it.
