PROBLEM
SOLUTION
Pulsation Flow - Pump cycles on and off
Restricted pump delivery. Check dischrage lines, fittings and valves for
undersizing or clogging. Clean screens in faucets. Some filters or purifiers
are highly restrictive. Filters/purifiers with high pressure drop may require
a separate line and/or the installation of an accumulator tank in the
system.

Restricted intake or dscharge line
Air leak in intake line
Punctured pump diaphragm
Debris under flapper valves
Crack in pump housing

Empty water tank
Punctured pump diaphragm
Discharge line leak
Defective pressure switch

Sanitizing
WARNING:
BEFORE SERVICING PUMP, TURN OFF PUMP AND DRAIN WATER FROM SYSTEM!!
TROUBLESHOOTING
www.jabsco.com
Potable water systems require periodic maintenance to deliver a consistent flow of fresh water. Depending on use and the
environment the system is subjected to, sanitizing is recommended prior to storing and before using the water system after a period
of storage. Systems with new components, or ones that have been subjected to contamination, should also be disinfected as
follows:
(
NOTE: The sanitizing procedure is in conformance with the approved procedures of the US Public Health
Service.)
1. Use the following methods to determine the amount of common household bleach needed to sanitize the tank:
A. Multiply “gallons of tank capacity” by 0.13; the result is the ounces of bleach needed to sanitize the tank
(30 gallons X .13 = 3.9 oz bleach).
B. Use the number of liters of tank capacity to determine the number of mililiters of bleach needed to sanitize the tank
(120 liters of tank capacity = 120 mililiters of bleach).
2. Mix into solution the proper amount of bleach within a container of water
3. Pour the solution (water/bleach) into the tank and fill the tank with potable water.
4. Open all faucets (hot and cold) allowing the water to run until the distinct door of chlorine is detected.
5. The standard solution must have four (4) hours of contact time to disinfect completly. Doubling the solution concentration allows
for contact time of one (1) hour.
6. When the contact time is completed, drain the tank. Refill with potable water and purge the plumbing of all sanitizing solution.
