CWS CWS Service Documentation & Warranty Management 2

Question 1

A service contract for a water treatment system should specify at minimum:

Accepted Answer

Service frequency, scope of work covered, response time, and cost

Answer

A well-written service contract must clearly define service frequency, what work is included, guaranteed response time, and pricing to set mutual expectations.

Question 2

When documenting a water softener's salt usage during a service visit, the technician should record this information to:

Accepted Answer

Track regeneration efficiency and detect abnormal salt consumption that may indicate a malfunction

Answer

Tracking salt usage over time helps identify inefficient regeneration cycles, salt bridges, or control valve malfunctions that increase operating costs.

Question 3

Which of the following should be included in a post-installation performance verification report?

Accepted Answer

Pre- and post-installation water hardness, iron, or other targeted contaminant test results

Answer

A performance verification report must show that targeted contaminants have been reduced to the specified levels, confirming the system is working as designed.

Question 4

For which scenario would a dealer most likely void a manufacturer's warranty on water treatment equipment?

Accepted Answer

Installation was performed by an uncertified technician using non-approved parts

Answer

Most manufacturers require installation by a certified professional using approved components; using unapproved parts or uncertified labor typically voids the warranty.

Question 5

A customer asks what their 'limited lifetime warranty' on a tank covers. A CWS professional should explain it most likely covers:

Accepted Answer

The tank vessel against defects, but not valves, electronics, or consumable parts

Answer

Limited lifetime warranties on tanks typically cover the tank vessel itself against cracking or structural defects but exclude control valves, electronics, media, and consumables.
