Trench Layout Guidelines. If the soil has been graded

and deemed acceptable, the next step is to gauge the

type of soil so that proper installation can proceed.

Installations shall be made in an acceptable soil

condition or prepared soil condition that supports the

tube against future settlement. ASTM D2774 and AWWA

report TR31 shall be additionally referenced for plastic

tube used for service work.

Installation In Different Soil Types

Good Soils. Tube may be directly installed on the trench

bottom. Code should be referenced for embedment

practices and necessary spacing requirements of the

tube in the ground. Tube should be laid into trench with

slack. Trench bottom is to be clear of any pits or humps

as well as sharp objects. Test tube. Compact initial

backll to prevent settlement. Test after backll.

Rocky Soils + Solid Rock. Tube shall have an additional

6" of trench dug below desired level of service tubing.

Prepared trench bottom shall have a 6" layer of pea gravel or

other non-sharp substrate trench base installed (pea gravel

suggested). Prevent humps or pits where tubing will be laid.

Test tube. Compact initial backll to prevent settlement.

Backll with 6" of the substrate used for the base. Test

after backll.

Unstable Soils. Tube shall have an additional 4" of

trench dug below the desired level of the service tubing.

Prepared trench bottom shall have a 4" layer of pea

gravel or other non-sharp substrate trench base installed

(pea gravel suggested). Prevent humps or pits where

tubing will be laid. Test tube. Compact initial backll to

prevent settlement. Backll with 6" of the substrate

used for the base.

Water Service Installation & Limitations

Getting Started. Local codes should be referenced for

acceptable pressures as well as special precautions

on use of PEX, system ttings, layout and installation

requirements for service piping. Typical water service

pressure requirements often mandate that the service

is capable of withstanding 1.5x the operating pressure

of the system it is supplying. See listed PEX pressure

ratings. Ensure the ttings and tubing being installed

are acceptable for potential pressures, stresses, and

application requirements.

Preparation. Check all tubing and ttings for proper

listings. Check all tubing and ttings for structural and

manufacturing integrity as well as issues that may have

arisen from transport or initial installation. Remove any

tting or tube section that has been subjected to cuts,

gouges or other excessive installation hazards. Make

sure proper analysis of soil and soil chemistry has been

completed. Make sure trench is prepared according

to guidelines.

Soil Analysis. Do not install PEX tube or ttings in areas

where known chemical spills have occurred or where a

likely chemical spill can occur. Do not install PowerPEX

tubing in soils contaminated with solvents, fuels, organic

solvents, pesticides or other harmful materials for

plastic tubing or its tting systems. Local plumbing code

authorities and Sioux Chief should be contacted if there

is a question on the installation or area of installation.

Note 1: Do not allow backll weight to cause tube

to become out-of-round beyond 5%. Do not over

compact backll.

Note 2:

Sioux Chief recommends using a sleeve material

for the entire length of the buried service main.
