Through two cross tests at KTL Korea Testing Laboratory,
99.9% odor blocking rate was thoroughly verified.

Drain trap structures that haven't changed for over a decade!
Now it's time for a change.

Even when used with a washing machine, if you position the hose in the center,
it will drain directly without overflowing.

Of course!Multi-Guide for Washing Machines is even better when used together :)
(See below for detailed instructions)

Remove foreign substances
So easy, right? :)

※ Only the DOMUS product line can be installed,
If you are unsure, please send us a photo via inquiry,
and we will guide you after checking.

※ After installation, do not press the main body located in the center of the product!

It will never come off under normal usage conditions.
However, due to the elastic nature of silicone,
it may come off if pressed strongly.
Do not press the main body while it is installed.

*When cleaning, 
Be sure to remove the drain trap from the drain before cleaning.
Please clean it.
(Most people drop it into the drain hole while cleaning!)

# When removing the product or cleaning it, always hold the 'protrusion' on the surface to take it out.

If you hold the protrusion to remove it, you can manage it much more easily.

# Never step on it with your foot when the drain cover is not in place.

[ Trap Ring(Blue, Gray) Usage Instructions ]

The purpose of having two trap rings is
To allow 'installation' in various environments, Therefore,
Please use them according to that purpose, And
The following methods are examples.

1) How to use only the blue silicone trap ring
(The most common usage form)

*For drains with a hole of about 50mm,The gray expandable trap ring is not used,
There is absolutely no risk of the product falling out.

2) How to use only the gray expandable trap ring
(Recommended: When the drain hole is 80mm or larger, or when the hole is too big)
(No matter how hard you press the main body, it will not come off)

# If you use the gray expandable trap ring, please cut along the trimming line with scissors.

Tip. It is easier if you insert the gray expandable trap ring in the default assembly state and then decide where to cut.

※ Please be careful with your hands when using tools, and it is easier to cut with large scissors like kitchen scissors.

※ Occasionally, the inside of the drain may be narrow or have become narrower.

If the product is installed but drainage is poor,
There may be lime or foreign substances inside the drain (see example photo).
This can interfere with the blocking part and prevent proper drainage.

In this case, use a drain cleaner or a wire brush,
and thoroughly remove any foreign substances attached to the inner wall before use to resolve the issue.

Hello, supporters!
This is Suwan Kim, the maker of the ultimate drain trap.

Have you been well?

Warm spring has already come close.

Cherry blossoms are in full bloom in front of our company.

The flowers are really beautiful these days, haha.

These days, I am working hard at my job!
I am also living diligently, raising two children and diving into the depths of parenting~!

I've even tried making those trendy Ghibli-style photos lately, haha.
(Maybe the trend... has already passed? Hahaha)

Someday, when my children grow up,

they will see the products I made,

and I want to be able to proudly show them off without any shame!

So I always do my best in developing and producing them, haha.

We would like to express our respect to all the parents in the world,

We also wish all our supporters the best of luck!

For this encore, we are introducing the newly improved honeycomb strainer,
and we are pleased to meet you again!

This time, we have developed and applied
the development goals of the #HoneycombStrainer as follows.

1. Improve the issue where foam or mucus clumps together to form a barrier and hinders drainage.
2. Add circular guide lines that make it easy to cut to fit the size of the drain hole.
3. Improve usability so that when installing with the multi-guide for washing machines, you only need to cut the central circular frame.
4. Improve the product color so that soap scum is less visible.

While still filtering debris as before,
we have put great effort into ensuring that drainage performance is not compromised.
We applied the honeycomb structure, which is the most space-efficient in the same area,
and created a new mold so you can use it even more neatly.
The color has also been changed from black to gray,
so you can use it even more cleanly.

Although the strainer does not have a major impact on the product's function,

Still!

There were some areas where usability could be improved even a little,
so we worked hard to make it.

You will probably be satisfied once you try it!

We will continue to work even harder in the future,
to ensure that we become the best product!

Thank you!

Sincerely, CEO Kim Suwan of Petrikoswan Co., Ltd.
