Purple Primer
Purple primeris used to pick and soften the PVC tobacco pipe ’s surface before utilise PVC cementum for reattachment . It avail in removing any dirt , oil , or ordinary adhesive remnants from the Earth’s surface of the pipe , ascertain a clear area for the Modern adhesive .
The ground also softens the top layer of the PVC , which allows for a in force bail bond when the new PVC cementum is applied . Its purple color helps to visibly designate the areas where it has been applied , see comprehensive coverage .
Clear PVC Cement

Couplings are especially utilitarian when you take to get in touch two cut organ pipe stop together , provide a secure and passing water - test copy joint .
How to “Unglue” and Glue PVC Pipes
Here ’s what to do :
Avoid the Heat Method
Using a heat gun or propane torch on PVC pipework posture significant danger due to the nature of PVC material and the high temperature involved . PVC , when exposed to high heat , can releasetoxic fumesincluding chlorine gas and dioxin , which are harmful if inhaled and can cause respiratory problem , eye irritation , and other wellness yield . The risk is compound in poorly ventilated area where these fume can accumulate .
Moreover , applying hotness to PVC requires deliberate control;excessive heatcan lead to the pipe melting or deforming , compromise its structural unity and potentially cause leaks or shift in the plumbing system . There ’s also a ardour luck to consider , as the in high spirits temperatures can ignite the PVC or nearby inflammable materials . Always expend safety goggles , obviate peel liaison , and work in a well give vent arena .
