RV Campground Hookups Explained for First-Time Travelers

Quick practical answer: what "hookups" mean and what you actually need

If someone says a site has “full hookups,” they mean three services: shore power (electric), potable fresh water, and a sewer connection. Each service has a few common variants—most importantly 30 amp vs 50 amp power and the way sewer hookups accept your hose. For first-time RV travelers, the basic checklist is: plug in safely, hook to a clean water source with a pressure regulator, and attach your sewer hose securely while keeping the connection sanitary.

Electric hookups: how to tell 30 amp from 50 amp and what to bring

Campground pedestals usually have clearly labeled outlets. 30 amp is a single-phase round or “A” shaped connector common on smaller RVs; 50 amp is two 50A poles that supply more power for larger rigs with multiple AC units, electric heaters or residential-style appliances. If your RV has a 30 amp inlet and the site is 50 amp, you’ll need a 50-to-30 amp adapter; the reverse (30 amp site for a 50 amp RV) will limit what you can run and may trip breakers.

• Bring: shore power cord (the right length), one high-quality adapter if your rig needs it, and a portable surge protector or electrical management system (EMS) to guard against bad wiring or unsafe voltage.
• Tip: inspect the pedestal before plugging in—look for frayed wires, burn marks, or loose outlets. If anything looks suspect, alert the host and request a different site.

Fresh water hookups: keeping water clean and protecting fittings

Fresh water means a potable spigot you connect to your RV’s city-water inlet. Use a dedicated drinking-water hose (not garden hose), and always install a water pressure regulator between the spigot and your hose—campground pressure can exceed what your RV’s plumbing tolerates. Some rigs prefer to use onboard tanks and fill periodically; for extended stays, city connection is more convenient.

• Bring: a white potable water hose, an inline pressure regulator rated around 40–60 psi, and a threaded spigot adapter if the campground uses nonstandard fittings.
• Sanitation: keep hose ends capped and flush the system if a campsite’s water tastes or smells off. Consider a small RV water filter if you frequently boondock or travel in areas with questionable supply.

Sewer hookups: the common types and how to avoid a mess

Sewer hookups normally provide a short standpipe or drop-in fitting at the site where you attach a sewer hose from your RV’s waste outlet. Colors and heights vary; some sites use an elevated box, others a ground-level inlet. The basic process is: close valves, attach hose to your RV, lead hose to sewer, then open gray (sink/shower) first to dilute and finally black (toilet).

• Bring: a heavy-duty flexible sewer hose, correct threaded fittings or adapters for the campground connection, and a support or ramp to level the hose so waste drains downhill without kinks.
• Tip: keep a removable elbow or elbow adapter and a short hand-held brush for terminal cleaning. Use disposable gloves and a spray bottle with a mild sanitizer for fittings when disconnecting.

Choosing adapters and extras that make hookups reliable

Adapters and accessories save frustration: an RV water pressure regulator, a quality surge protector/EMS, the right shore power cord length (25–50 ft depending on site spacing), and a robust sewer hose assembly with threaded connectors are core items. Also consider blind-spot extras like a sewer support kit (to create a downward grade), a 12V-to-120V converter if boondocking, and a set of spare fuses for the electrical bay.

Safety and etiquette at hookup sites

Safety is both personal and communal. Never leave electrical connections exposed to standing water; if a pedestal is wet after rain, ask for a different site. Use surge protection and confirm your ground is showing properly (many EMS units indicate wiring faults). For sewer etiquette, keep the connection covered, minimize hose exposure in public areas, and never drain black water into anything but the designated sewer inlet.

• Respect site sizes—don’t extend hoses or cords across another site without permission.
• When in doubt, ask the host. They can point out site quirks like low water pressure, occasional power trips, or shared sewer boxes.

Common hookup problems and simple fixes

• Power trips when AC turns on: try a lower-draw setting, move items off a single circuit, or request a 50 amp site if you regularly run multiple appliances.
• Low water flow: check the regulator, clear any kinked hose, and inspect your RV inlet screen if present.
• Sewer backups or leaks: confirm seals, tighten threaded connectors, and use a support to prevent reverse slope toward your RV.

When to skip hookups and when they’re nonnegotiable

Hookups are optional if you plan to boondock or dry camp for a night or two and have sufficient fresh water and battery capacity. They become nonnegotiable for long stays, hot-weather travel (AC), or when your itinerary requires frequent laundry and showering. Renting or towing a travel trailer? Plan hookups to match your rig’s service needs—don’t assume every site has a specific outlet until you book or arrive.
