Whole-Home Pressure Relief at Hose Bibs With Visual Pressure Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure relief valves are difficult for average homeowners to install and do not effectively relieve pressure before water heaters burst, especially when positioned outside the home's plumbing system.
Innovation Solution
A whole-home pressure relief system with a main body, inlet and outlet ends, and a flow restrictor channel, designed for easy installation on existing connections like exterior hose bibs, featuring a visual indicator to show pressure buildup through a transparent sight cup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pressure relief valves are used, then pressure relief function is provided, but installation difficulty increases and homeowner accessibility deteriorates
Solution Approach 1:
The pressure relief valve is nested within the main body housing, which itself connects to standard hose bib threads. This nested structure allows the complex pressure relief mechanism to be contained within a simple external interface that homeowners can easily install using standard plumbing connections.
Solution Approach 2:
The main body acts as an intermediary component between the standard hose bib connection and the pressure relief valve mechanism. This intermediary structure provides standard threaded connections for easy installation while housing the specialized pressure relief components internally.
2Ease of operation
If pressure relief valves are installed outside the home's plumbing system, then installation simplicity improves, but pressure relief effectiveness deteriorates
Solution Approach 1:
The device is designed with universal threading that matches standard hose bib connections, allowing it to be installed externally while still effectively relieving pressure from the entire home's plumbing system. The flow restrictor channel ensures proper pressure regulation throughout the system.
Solution Approach 2:
The device segments the pressure relief function into a separate, externally-installable unit that connects to the existing plumbing system through standard hose bib threads, rather than requiring integration into the main plumbing infrastructure.
3Reliability
If pressure relief valves are installed inside the home's plumbing system, then pressure relief effectiveness improves, but installation complexity increases
Solution Approach 1:
The main body serves as an intermediary that connects the external installation point (hose bib) to the internal pressure relief mechanism, simplifying installation while maintaining effectiveness.
4Difficulty of detecting and measuring
If visual indicator is added to show pressure buildup, then pressure monitoring capability improves, but device complexity increases
Solution Approach 1:
The sight cup uses visual indication through water presence or color changes to show pressure buildup conditions, providing clear pressure monitoring feedback to users without requiring complex electronic sensors or indicators.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables homeowners to easily install a pressure relief system that visually indicates pressure issues, relieving excess pressure throughout the entire home's plumbing system, preventing damage from high water pressure.
Implementation Method 1
a flow restrictor channel extending from a bottom end of the inlet end toward a central portion of the main body

AI summary
A whole-home pressure relief system for relieving pressure from a home's plumbing system may include a main body having an inlet end, an outlet end, and a hollow interior; inlet threads extending into an interior wall of the inlet end, the inlet end and inlet threads configured to removably engage with female threads on a conventional hose bib; a flow restrictor channel extending from a bottom end of the inlet end toward a central portion of the main body; a valve chamber within the interior of the main body, the valve chamber in fluid communication with the flow restrictor, wherein the valve chamber is configured to accept a pressure relief valve such that a valve inlet is in fluid communication with the flow restrictor; and outlet threads extending into an interior wall of the outlet end.
