A full report on how to replace the faucet that could not supply water to the pot with an easy-to-use shower type

The faucet (faucet fitting) in the kitchen of the GIGAZINE editorial department is very simple without a water purification function or a water flow switching function. Even so, I came without any major complaints, but from the time I renewed the electric kettle, the problem that water supply was difficult because the pot was too big to fit under the faucet emerged. I've been fooling myself, but I decided to replace it with a hand shower type because I think it's finally necessary to solve the problem fundamentally.

The faucet before replacement looks like this.

KVK 's KM5011NTHT is a simple faucet that does not have functions such as water purification.

I didn't have much trouble with it for everyday use, but when I changed the electric kettle in the kitchen to '

Steamless VE Electric Mahobin <Tokuko-san> PIE-A500 ', the height was 40 cm, so water was supplied. Sometimes even in the sink, there is a problem that it does not go under the faucet.

In order to supply water directly from the faucet, we needed a slightly strange method of tilting the pot a little and inserting it under the faucet. However, there is no pot of the same size and capacity as before, and if you reduce the capacity, there will be cases where the kettle will not be in time, so we decided to replace it with a faucet that can use the pot.

A minimum length of approximately 60 cm is required from the base to the tip of the faucet to allow water to be supplied without dropping the pot into the sink.

'Speaking of products around the kitchen,' I decided to search for products sold by ' TOTO ' and ' LIXIL .'

First, access the page of TOTO's kitchen faucet fittings. There was a 'hand shower type' in the item 'select from functions' in the center of the page, so click it.

There are two types of faucets, one is a 1-hole type and the other is a 2-hole type, which is installed in the faucet mounting hole of the sink, and there is also one that is mounted on the wall. In the case of the kitchen this time, there were 5 types of '1 hole with stand' type and hand shower type products.

Next, access

the page of LIXIL's kitchen faucet fittings and click 'Kitchen faucet one-hole type'.

Since the catalog opened, I searched for it and found that 6 items of 'hose drawer type' and 'one-hole type' were lined up on page 939. Although the name is different from that of TOTO, it seems to have the same function.

The question is, is there a product with a maximum length of about 60 cm when the hose is pulled out from the base of the faucet to the tip of the faucet? When I looked it up, there was no page that stated that 'the length from the base to the tip of the faucet is this'. However, I found detailed pages such as 'faucet length' and 'length when the hose is pulled out' for all products, so I will calculate the required length myself.

For example, if you look at

the specification list on the product details page of TOTO's TKS05308J , there is a description of 'spout length 255 mm' and 'hose drawer length 450 mm'.

When I searched for a product called

SF-HB452SYX from LIXIL, the product page stated that 'the spout length was 250 mm' and 'the hose drawer length was 400 mm'.

' Spout length ' and ' spout length ' are 'the length of the

heart from the base to the tip of the nozzle'. For example, the spout length of KM5011NTHT is 300mm. In other words, we came to the conclusion that there would be no problem if we chose a product with a spout length + hose pull-out length exceeding 600 mm.

That 's why I focused on LIXIL's SF-A451SYXU product. The spout length is 250 mm, and the hose drawer length is 400 mm. The total length is 650mm, which is enough for the required length. It doesn't have unnecessary functions such as water purification function, it looks like KM5011NTHT, and it can be used without any discomfort even if it is replaced.

First of all, I bought the product, and when it arrived, I asked a water supplier to install it. This is the one that arrived about a week after I ordered it.

The internal use is the faucet body. After installation, the hose part that is hidden inside the sink and cannot be seen is exposed.

And there are 6 small parts. I put the iPhone 12 Pro for size comparison.

When I called the water supplier, he would come to the construction on the same day. There is one worker. First, I removed the drawer under the sink and closed the water stopcock.

There was a color label on the hose so that even an amateur could tell that the left was hot water and the right was cold water.

Then remove the hose from the stopcock.

Next, the metal fittings and plates near the faucet mounting holes will be removed.

After some work, the old faucet was completely removed.

It is the removed KM5011NTHT.

Next, we will install a new faucet. First, attach a group of small parts to the mounting holes ...

I will go through the hose.

Tighten the screws to complete the installation.

Finally, it is attached to the water stopcock under the sink and the position of the hose is adjusted.

The construction was completed in about 30 minutes, and water began to come out.

Now you can supply water without dropping the electric kettle into the sink.

The actual length when the hose was pulled out was about 43 cm. The length is roughly as specified.

Water now reaches the corners of the sink, so cleaning is sure to be quick.

The construction was very fast and completed in no time, and the environment around the water became comfortable. Even if it is a rental house, you can replace the faucet by negotiating with the landlord to 'make it better than the product you are currently using' or by consulting on the condition that the faucet will be restored to its original state when you move out. He often does it. There are various advanced faucets such as 'water purification function' and 'touchless type' that were not included in the candidates this time, so it may be worth considering.

The cost this time was 24,782 yen including tax for the purchase of 'SF-A451SYXU' and 8,800 yen including tax for the construction work.
