Common Concerns Answered
Some users report a slight decrease in pressure over extended periods if not properly maintained. How can this be avoided?
Maintain the air charge pressure according to the manufacturer's specifications. Periodic checks of the air bladder's integrity and system pressure will ensure consistent performance and prevent gradual pressure loss.
The initial cost may be higher than simpler, non-bladdered tanks. What justifies this investment?
The GROCO PST-2's bladder technology significantly reduces pump wear by minimizing cycling, leading to longer pump life and reduced replacement costs. The improved water pressure consistency also provides a more comfortable user experience.
Initial setup can be confusing for novice installers. What guidance is available?
The unit includes mounting hardware and requires basic plumbing knowledge. Referencing the provided manual and ensuring proper connection to the pump and water line will facilitate a successful installation for most users.
Frequently Asked Questions

The internal rubber bladder acts as a barrier, separating the air charge from the system water, thereby preventing the air from being absorbed into the water, which is the primary cause of waterlogging.
Can the GROCO PST-2 be used for both fresh and saltwater systems?
Yes, the GROCO PST-2 is suitable for use in both freshwater and saltwater onboard marine systems.
What is the drawdown capacity of the GROCO PST-2?
The GROCO PST-2 provides a usable drawdown capacity of 1.4 gallons before the pressure switch activates the pump.
What is the thread size for the GROCO PST-2?
The GROCO PST-2 features a 3/4" NPT (National Pipe Taper) thread for its water connections.
Can the GROCO PST-2 be mounted in any position?
Yes, the design of the GROCO PST-2 allows for mounting in any orientation, providing flexibility during installation.
