Hot/Cold Water PEX Pipes vs. Welding Method: Comparing Kitchen Plumbing Solutions

Question

Hello, I plan to replace the pipes in the kitchen with cold and warm water from a boiler and my question is what is better to use pexes for clamps or welding methods, please describe why this method is better and why other pipes should not be in the wall

wnojtek · Accepted Answer

Both systems are comparable. Just let a professional work in a system where he works better and has more experience.

Hello. I recommend and use the TeceFlex system. It is expensive but also good, and it goes hand in hand And by the way, every pipe for hot or cold water should be wrapped in lagging for example:

I'm not a plumber or I don't know what peks are, but at home I did everything on plastic pipes and fittings. Advantage? A huge time saver. This has only been done in the UK for over 10 years.

The gentleman who would make me welds is a stabilized welded polypropylene system

roman 18 · Answer

Hello, buddy, do a water installation as proposed by a plumber, welded polypropylene pipes, but they do not have to be stabilized pipes since they will be in furrows in the wall, it is good to fill these furrows with mounting foam to allow squeezing of these pipes. best regards.

Thanks for the hint please further information

Both systems are good for this purpose and widely used in older and new installations.

Hmm or better I would like to do as I took the welded ones

dymior · Answer

I worked with both PEX and welded ones, welds are made faster, but in my opinion PEX works better and in my opinion it is more durable.

Generally, it is more resistant to any impacts, deformations etc. because it is very flexible. For example, you can make bends, bends, etc., without having to install fittings, hence the fewer connections the more secure when it comes to tightness.
Welded PE pipes are only a little flexible, if you have cold water in the pipe and someone collapses vertically, it may burst, I met with it.
In general, they must not be packed into a furrow without protective foam so that they can work!

andrzej lukaszewicz · Answer

Pexa must also be covered in lagging. As many points (bathrooms, toilets), PE comes out much cheaper due to the low price of PE fittings. Pex fittings are expensive, in addition, they have high hydraulic resistance due to large constrictions in tees, knees, but many knees can be avoided by using bending pipes.

mychaj · Answer

I am for PEX:
1.for welded, you need more space, pipes and fittings are larger, so more forging,
2. PEX bends well with a spiral: fewer elbows and fittings
3. PEX can always be improved as if something unsealed - you will tighten or replace the coupling, the welded ones will have to be cut and cut,
4. welded have thicker walls, they look more solid but the same in terms of strength,
5. in tight places it doesn't weld well.
In general, I do not like one-time installations that do not allow corrections - that is, welded, clamped or glued ... but this is my perversion ... :-)

This will be done by a professional but I wanted to find out what is better

The professional said that they would use something to put the pipe in
