Predicted depth of penetration into the ground zero of temperature should be set:

* Based on observations of the actual depth of freezing in the cold, calculated and little snow in winter;
* Experience of PEX tubing operation in this area taking into account possible changes previously observed freezing depth as a result of proposed changes in the status area (removal of snow cover, the device improved road surfaces, etc.).

In the absence of observational data the depth of penetration into the ground zero of temperature and its possible changes due to assume the changes in landscaping should be liquid nails.

To prevent heating of water in the summer depth of the tubing plumbing should be taken not less than 0,5 m, starting from the top of the tubing. Allowed to take a lesser depth of the water lines or sections of water mains, provided justification thermo calculations.

Tubing made of PEX can be used both for plumbing and sanitation pressure.
