How to mount connections ⠀
⠀
It’s not enough to choose a quality product, ⠀
it is necessary to lay the pipeline correctly and mount reliable connections. Most often, water PND connections ⠀
make on collet fittings. ⠀
⠀
🔰 Since there are no metal parts in the flow part of compression fittings, this increases the corrosion resistance of the piping system made of this material. ⠀
⠀
Mounting ⠀
On collet fittings, some key features must be considered. ⠀
⠀
🗣 - Assembled the system. Despite the use of fum tape and a decent tightening, some HDPE fittings are leaking. ⠀
⠀
When mounting a collet fitting, do not use flax, tow or fum tape “for extra reliability”. ⠀
⠀
🗣 - Collet fittings are simply tightened by hand and that’s it. ⠀
⠀
The longer the fitting, the more turns must be made to clamp it. Pipes for water supply are inserted into the fitting until they stop, and not until the rubber band. ⠀
⠀
⠀
Sometimes you can hear the opinion that if you lay the PND pipeline on the ground, then nothing will happen to it, but this is not so. ⠀
⠀
⠀
⠀
🗣 - PND products are unstable to sunlight. According to GOST, they are allowed to be stored under the sun for a maximum of two months. And this is in ideal conditions when the manufacturer fully complies with the technology and uses pipe polyethylene. ⠀
⠀
Therefore, the pipeline from HDPE is best buried in the ground. And to do it better to a depth below freezing, this will allow the fittings not to freeze. ⠀
⠀
A high-quality modern HDPE pipe withstands a large number of freezing and thawing cycles without destruction, but for fittings, even the most expensive, any freezing is fatal. ⠀
⠀
⠀
⚙ The installation process itself is as follows: ⠀
⠀
1. Dig a narrow trench 2 meters deep ⠀
⠀
2. Stones are removed from the trench, otherwise they can push through the walls of the product ⠀
⠀
3. Lay the pipe (not tight, this is a general rule!) And sprinkle it with sand ⠀
⠀
4. If necessary, the water supply is additionally insulated ⠀
⠀
5.⠀
The trench is completely buried ⠀
