Common Concerns Answered
The initial cost seems higher than non-bladdered tanks. Is it worth the investment?
Yes, the GROCO PST-2's bladder design prevents waterlogging and reduces pump wear, leading to a longer system lifespan and more consistent pressure, justifying the initial investment through reduced maintenance and improved performance.
Some users report a decrease in pressure over time. How can I prevent this?
Proper maintenance, including periodic checks of the air charge pressure, is crucial for sustained performance. Ensure the tank is installed according to manufacturer guidelines to maintain optimal functionality.
Is the setup process complex for a DIY installer?
While it requires basic plumbing knowledge, the GROCO PST-2 includes mounting hardware and clear specifications to guide installation. Understanding your existing water pressure system is beneficial.
Frequently Asked Questions
How does the GROCO PST-2 prevent waterlogging?
The integrated rubber bladder physically separates the air charge from the system water, preventing the air from being absorbed into the water, which is the cause of waterlogging in simpler systems.
Can the GROCO PST-2 be used for both fresh and saltwater systems?
Yes, this tank is suitable for use with both fresh and saltwater applications, providing consistent pressure for a variety of onboard water needs.
What is the drawdown capacity of the GROCO PST-2?
The GROCO PST-2 offers a significant 1.4-gallon drawdown capacity, meaning it can supply this volume of water before the pressure switch activates the pump.
What is the thread size for connecting plumbing to the GROCO PST-2?
The GROCO PST-2 features a 3/4" NPT thread for secure and reliable connection to your marine plumbing system.
Can the GROCO PST-2 be mounted in any orientation?
Yes, the stand mounting design of the GROCO PST-2 allows for installation in virtually any position, offering flexibility to accommodate various onboard configurations.
