Common Concerns Answered
What is the expected longevity of the rubber bladder?
The rubber bladder generally offers excellent durability, though longevity can be influenced by very high-use cycles or specific water conditions. Regular inspection and maintenance are recommended for optimal performance.
Is it difficult to set the correct air pre-charge pressure?
Achieving optimal pre-charge pressure requires basic understanding and potentially specific tools. We recommend consulting the installation manual or a qualified marine technician if you encounter difficulties.
Does the tank have a high initial cost?
While the initial investment may be higher than basic diaphragm tanks, the GROCO PST-1's advanced bladder design and superior pump protection provide long-term value through reduced maintenance and enhanced system reliability.
