Hello everyone, my plumber wants to install a ring circuit for cold and hot water in my bathroom (see sketch).
He plans to extend the 18mm (3/4 inch) hot water supply line through the bathroom and then connect it at the end of the loop to the 15mm (1/2 inch) hot water circulation line... Is this really the correct method?

Thanks

Good evening
The hot water ring main is already fine as it is.
Cold water can be installed like this, but it is not necessary.

The I-box should definitely be secured at all four designated points; otherwise, it might bend at another spot since these plastic fasteners are not as sturdy as they appear (this happened to me).

The insulation should cover every part of the pipe; otherwise, heat will be lost and condensation might form at the uncovered sections.

The pipe installation can be done like this, but it doesn’t exactly reflect well on the plumber.

Here’s how it looks at my place:

Round metal connector with four outlets; red and blue pipes in the basement.

Geberit installation frame with flush tank; blue and red plumbing pipes in the shell construction.

Red and blue water lines leading to a green round valve body on a shell construction site.

You can do the cold water that way, but it’s not necessary.

The I-box should definitely be secured at all 4 designated points; otherwise, it might bend at another spot since these plastic mounts aren’t as sturdy as they look (this happened to me).

Insulation should cover the entire length of the pipe to prevent heat loss, and possibly also condensation at that point.

Hello and thanks for the reply. Actually, it doesn’t matter whether the pipes are neatly installed since plaster will cover them, but it still annoys me because it was just carelessly slapped onto the wall. Yours looks similar.
