Buying Guide
What should I look for in a city water inlet?
Key factors include material quality (prefer brass for durability and safety), backflow prevention (check valve presence), thread compatibility (common sizes are 3/4 NH to 1/2 NPT), and housing durability (plastic vs. metal). Consider whether you want a ready-to-install flange and if you need lead-free components for drinking water safety.
Brass vs. plastic housings
Brass inlets offer superior longevity and strength in outdoor environments. Plastic housings are lighter and can resist impact, but may show wear more quickly under harsh conditions. For rugged camping trips, brass with a sturdy mounting flange is typically more reliable.
When is backflow prevention essential?
Backflow prevention prevents contaminants from your RV’s system from entering the external water supply. If you camp in areas with variable water pressure or older hookups, a device with a reliable check valve is highly recommended.
Installation considerations
Check thread compatibility with your existing hoses and fittings. Some inlets require adapters or a specific flange size. If you are replacing an old inlet, match the thread size and mounting footprint to minimize modification work.
Pros and cons at a glance
- Best overall durability: Inlets with brass bodies and sturdy housings, designed for frequent use.
- Best value: Simple inlets with reliable check valves for casual campers.
- Best for lead-free safety: Inlets explicitly using lead-free brass.
