Frequently Asked Questions

Click a frequently asked question below to see the answer.

What is included with the PB4SQ?
The PB4SQ comes with 4 Quick Connect fittings and a 6’ length of Polaris Softube® for installation.
How is it so much more efficient?
The multistage design progressively pressurizes the water as it passes through each stage – effectively moving more water with less energy.
Do you have to adjust the cleaner speed after installation or change restrictor discs?
The cleaner should be checked for proper speed after installation of the PB4SQ booster pump and any necessary adjustments made.
How much quieter is it?
It is much quieter than the PB4-60 and has been designed with a TEFC motor and new fan that reduces noise.
What is a TEFC motor?
TEFC stands for Totally Enclosed Fan Cooled. It is a motor that does not permit outside air and requires a fan to cool it. TEFC motors are generally more durable and operate quieter than open motors.
