Water Hammer Arrestor Isolation Valve With Bleeder Drain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Water hammer arrestors in plumbing systems require replacement or servicing, which often necessitates shutting down the entire system and lacks a mechanism for pressure release and fluid drainage, making the process cumbersome and inefficient.
Innovation Solution
A tee-shaped isolation valve assembly with bleeder drain ports and a flow diversion mechanism that allows for pressure release and fluid drainage adjacent to the water hammer arrestor, enabling simplified replacement and servicing without shutting down the plumbing system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional water hammer arrestor is installed in a plumbing system, then water hammer pressure waves are absorbed and plumbing damage is prevented, but the entire plumbing system must be shut down for replacement or servicing and there is no mechanism to release pressure or drain fluid
Solution Approach 1:
The valve assembly is divided into multiple functional sections: isolation valve portion, bleeder drain portion, and flow diversion member. This segmentation allows independent operation of each function - the isolation valve can close off the water hammer arrestor for servicing while the bleeder drain can release pressure, and the flow diversion member can redirect flow to facilitate drainage without shutting down the entire system.
Solution Approach 2:
The flow diversion member acts as an intermediary mechanism that redirects water flow between different pathways. It can divert flow away from the water hammer arrestor to enable draining through the bleeder drain port, or redirect flow to maintain system operation, thereby mediating between the need for servicing and system continuity.
2Reliability
If a traditional water hammer arrestor is installed in a plumbing system, then water hammer pressure waves are absorbed, but replacement or servicing requires shutting down the entire plumbing system causing downtime
Solution Approach 1:
The valve assembly is divided into multiple functional sections: isolation valve portion, bleeder drain portion, and flow diversion member. This segmentation allows independent operation of each function - the isolation valve can close off the water hammer arrestor for servicing while the bleeder drain can release pressure, and the flow diversion member can redirect flow to facilitate drainage without shutting down the entire system.
Solution Approach 2:
The bleeder drain port and flow diversion member enable preliminary actions to be taken before servicing - pressure can be released and fluid can be drained from the water hammer arrestor while the rest of the system remains operational, preparing the arrestor for quick replacement without system shutdown.
3Reliability
If a traditional water hammer arrestor is installed in a plumbing system, then water hammer pressure waves are absorbed, but there is no mechanism to release pressure or drain fluid adjacent to the arrestor
Solution Approach 1:
The isolation valve, bleeder drain, and flow diversion member are merged into a single integrated valve assembly that couples with the water hammer arrestor. This combination provides pressure release and drainage functions without requiring separate, additional components, thereby reducing overall system complexity while adding necessary functionality.
Solution Approach 2:
The valve assembly serves multiple functions: isolation of the water hammer arrestor, pressure release through the bleeder drain, and flow diversion for drainage. This multi-functionality consolidates what would otherwise require separate components into a single universal device.

AI summary
A water arrestor valve assembly permits the servicing and/or replacement of a water hammer arrestor in a segment of a plumbing system. The water hammer arrestor can be isolated from the incoming and outgoing water supply by a valve or a tee-shaped valve body. In addition, the bleeder drain valve(s) can be located on the tee-shaped valve body to reduce the pressure and drain fluid before removal of the water hammer arrestor and can also be used to isolate, reduce the pressure and drain the length of piping of the fixture/appliance that is downstream of the water hammer arrestor.
