Frequently Asked Questions

Q: Will this nipple work with my Dometic freshwater system?

Q: What's the difference between Schedule 80 and Schedule 40 PVC?
A: Schedule 80 has thicker walls and a higher pressure rating, making it more durable for RV plumbing applications where vibration and temperature fluctuations are common.
