Hello. We are sorry to hear about your poor experience
with the SharkBite 3/4 in. Push-to-Connect PVC IPS x CTS Brass Conversion Coupling. Our products are intended for long- term use, and we stand behind our products with a warranty of 25 years. The most common reason for failure is not pushing the SharkBite to the full insertion depth. For a 3/4 in. SharkBite fitting, the insertion depth is 1-1/8 in. We also recommend ensuring your pipe is cut straight. If you have any questions about installation, feel free to reach out to our Customer Service Team to help (1-877-700-4242).
