As a result of water freeze, the brass body is more susceptible to fracturing.
What is a vacuum leak?
A vacuum leak is a small hole in one or several parts of the system that allows the uncontrolled entry or exit of gas. The leak rate is dependent on several factors, including the size of the hole, gas type, and the pressure differential (between the inside and the outside of the system).

How to identify a vacuum leak?
How do you identify vacuum leaks? There are four ways to identify vacuum leaks: the bubble test, the pressure decay test, the pressure rise test and the helium sniffer mode/helium vacuum test. The tests – in order of mention – correspond to low to high vacuum respectively.
What is the purpose of vacuum leak testing?
Leak testing and measurement, therefore, are just to identify the position of a leak and the rate of leakage. Once the position and rate of leakage are recorded, steps can be taken to minimise it.
Why is helium used to measure vacuum leaks?
Helium is typically used not just because of its ability to measure small vacuum leaks, but also because it’s very mobile (low mass), completely inert/non-reactive (and therefore harmless) and is available at a relatively low cost. Find out four ways to find vacuum leaks using helium.
How to minimize leakage?
Once the position and rate of leakage are recorded, steps can be taken to minimise it. Here’s what you can do: 1. Check your seals. Most leaks occur in a vacuum system at joints to components (seals). This includes pump lines, chamber doors and electrical leadthroughs.

How does a vacuum breaker work?
When the water is on, water pressure forces the diaphragm down, opening the valve and allowing the water to flow. When the water is off, a spring or the force of atmospheric pressure forces it back against the water inlet, forming a seal that prevents any water from flowing backward. If a vacuum develops in the water line, it only serves to strengthen the seal.
