What "Connect RV" Means and Where to Start
Connect RV refers to the process of linking your recreational vehicle to permanent or semi-permanent utility services — typically water, sewer, and electrical hookups at an RV park, campground, or private property. Unlike boondocking (dry camping), a connected RV draws power from a pedestal or shore power line, drains waste into a sewer system, and fills fresh water from an external source rather than onboard tanks.
The connection itself is straightforward in mechanics but requires you to understand what your RV needs, what the site provides, and what equipment sits between them. Most RV parks have standardized hookup configurations, but the details — voltage available, water pressure limits, sewer connection type — vary enough that knowing what to check before you arrive saves time and prevents damage.
Your first step is confirming what your RV can accept. Check your owner's manual or the exterior of your RV for the amperage rating (usually 30 or 50 amps), the fresh water inlet location, and the waste outlet configuration. Then contact the park or property owner to learn what they provide and whether it matches what you need.
Key Takeaways
- RV hookups come in three types — electrical (30 or 50 amp), water, and sewer — and your RV may not need or accept all three.
- Electrical pedestals at parks supply either 30-amp or 50-amp service; plugging a 50-amp RV into a 30-amp pedestal requires a special adapter and limits your power use.
- Water pressure at the site can damage your RV's plumbing if it exceeds 60 PSI, so most RVers carry a pressure regulator to install between the park spigot and their fresh water inlet.
- Sewer connections vary by park — some use pull-through drains, others require you to connect a hose to an underground outlet — so confirm the method before arrival.
- You will need specific cables, hoses, and adapters; buying them piecemeal at parks costs more than bringing them from home.
Understanding the Three Types of RV Hookups
Most RV parks offer hookups in three categories: electrical, water, and sewer. Not every site provides all three, and not every RV uses all three. A small travel trailer might need only electrical and water; a Class A motorhome with a full waste system needs all three.
Electrical hookups deliver power to your RV's onboard batteries and appliances. The two standard sizes are 30-amp and 50-amp service. A 30-amp pedestal has a single outlet that looks like a large three-prong plug; a 50-amp pedestal has a four-prong outlet. Your RV's shore power inlet matches one of these. If your RV is rated for 50 amps but the park offers only 30-amp pedestals, you can use an adapter, but you will be limited to drawing 30 amps total — meaning you cannot run your air conditioner and electric water heater simultaneously.
Water hookups connect to your RV's fresh water tank or directly to your onboard plumbing. The park provides a spigot or outlet; you connect a hose from there to your RV's fresh water inlet. The critical detail is pressure: municipal water systems often run at 60 to 80 PSI, which can burst RV pipes and fittings designed for lower pressure. Most RVers install a pressure regulator between the park spigot and their hose to keep pressure below 60 PSI.
Sewer hookups drain your gray water (sinks and shower) and black water (toilet) tanks. Some parks have pull-through drains where you position your RV over a grate and open your tanks; others have individual outlets where you connect a sewer hose. The hose itself is rigid or flexible, and the outlet connection varies — some use a standard threaded fitting, others a different size or type. Confirm the method and bring the correct hose before you arrive.
Electrical Connections: Amperage, Adapters, and Safety
Your RV's electrical system runs on 12-volt DC power from onboard batteries and 120-volt AC power from shore power (the park's pedestal). When connected, the pedestal charges your batteries and powers your appliances. The amperage available determines how much you can run at once.
A 30-amp service delivers 3,600 watts (30 amps × 120 volts). A 50-amp service delivers 12,000 watts (50 amps × 240 volts, split into two 120-volt legs). If your RV is wired for 50 amps and you plug into a 30-amp pedestal using an adapter, you get only 30 amps total. Running a 13,500-BTU air conditioner (about 15 amps) and an electric water heater (about 12 amps) simultaneously will trip the breaker.
The shore power cord connects your RV's inlet to the pedestal outlet. Standard cords are 25 feet long; longer cords are available but introduce voltage drop over distance. Inspect your cord before each trip for cracks, cuts, or corrosion. If the cord is damaged, replace it — a damaged cord can cause electrical shock or fire.
When you arrive at a site, inspect the pedestal before plugging in. Look for cracks, water damage, or loose connections. If the pedestal looks unsafe, ask the park to inspect it or move to a different site. Once you plug in, your RV is energized; treat the connection as live electricity.
Water Connections: Pressure, Hoses, and Tank Management
Connecting to the park's water supply fills your fresh water tank or feeds your plumbing directly. The connection is straightforward — a hose from the park spigot to your RV's inlet — but the details matter.
Water pressure is the main concern. RV plumbing is built for low pressure; city water often runs at 60 to 80 PSI or higher. Pressure above 80 PSI can crack fittings, burst hoses, or damage your water heater. A pressure regulator screws onto the park spigot and reduces the incoming pressure to a safe level (usually 40 to 60 PSI). This is a cheap, essential tool — bring one from home rather than buying one at the park.
Your fresh water hose should be food-grade and rated for potable water. Standard garden hoses leach chemicals into drinking water. A typical RV fresh water hose is 25 feet long; longer hoses are available but take up storage space. Before connecting, run the park water for a few seconds to clear debris from the spigot, then attach your hose.
If you are filling your fresh water tank rather than running directly from the park supply, position your RV so the inlet is accessible and the hose does not kink. Most tanks hold 50 to 100 gallons; filling takes 10 to 20 minutes depending on water pressure. Turn off the water when the tank is full — overfilling can damage the tank vent.
Sewer Connections: Hose Types, Outlet Configurations, and Waste Management
Sewer connections drain your gray and black water tanks. The method varies by park, so confirm before you arrive.
Pull-through drains are the simplest: you position your RV over a grate, open both tank valves, and let gravity drain the tanks. No hose is needed. This method is fast and common at many parks, but you cannot leave the tanks open while parked — you must open them only when actively draining.
Individual sewer outlets require you to connect a sewer hose from your RV's outlet to the park's inlet. The hose is rigid (PVC pipe) or flexible (accordion-style). Rigid hose is durable but harder to store; flexible hose is compact but more prone to kinking and damage. The outlet connection varies: some parks use a standard threaded fitting, others a different size or a bayonet-style lock. Bring the correct hose and adapters, or ask the park what they use before you arrive.
When connected to an individual outlet, you can leave the gray water valve open (it drains continuously), but keep the black water valve closed until the tank is full. This prevents solids from settling in the hose. When the black tank is full, open the valve, let it drain completely, close the valve, and rinse the hose with fresh water if possible.
After disconnecting, cap both your tank outlets and the park's inlet to prevent spills and odors. Store the sewer hose in a dedicated container — never in the same space as fresh water hoses or food.
Essential Equipment and What to Bring
Before you connect at a new park, you need specific items. Buying them at the park costs significantly more than bringing them from home. The table below lists what you need, why, and what to watch for when purchasing or using each item.
| Item | Purpose | Notes |
|---|---|---|
| Shore power cord (25 ft) | Connects RV inlet to pedestal | Match your RV's amperage (30 or 50 amp). Inspect before each trip. |
| Fresh water hose (25 ft, food-grade) | Fills tank or supplies plumbing | Never use a standard garden hose for drinking water. |
| Water pressure regulator | Reduces incoming pressure to safe level | Essential. Prevents damage to plumbing and fittings. |
| Sewer hose (flexible or rigid) | Drains gray and black tanks | Confirm park outlet type before buying. Store separately from fresh water hose. |
| Hose adapters | Connect mismatched hose sizes | Parks use different outlet sizes. Bring common sizes (3" and 4"). |
| Tank caps and outlet caps | Cap tank outlets and park inlets | Prevent spills and odors when disconnected. |
| Electrical adapter (if needed) | Converts 50-amp inlet to 30-amp pedestal | Only if your RV is 50-amp and you park at 30-amp sites. |
Most RV supply stores sell kits that bundle the essentials — shore power cord, fresh water hose, pressure regulator, and basic adapters — at a lower total cost than buying items separately. These kits are worth the investment if you plan to use hookups regularly.
Disconnecting and Winterizing Before You Leave
When you are ready to leave, disconnect in the reverse order: sewer first, then water, then electrical. This prevents backflow and contamination.
For sewer, close both tank valves, disconnect the hose from your outlet, cap your outlet, and cap the park's inlet. Rinse the hose with fresh water if available, then store it in a dedicated container.
For water, turn off the park spigot, disconnect the hose from your inlet, and cap your inlet. If you are leaving for an extended period or heading into freezing weather, drain your fresh water tank and all plumbing lines to prevent freeze damage. Your RV's manual will explain how to access the drain valves.
For electrical, turn off all major appliances (air conditioner, water heater, microwave) before unplugging. This reduces the surge when you disconnect and protects your RV's electrical system. Unplug slowly and store the cord in a dry location.
Frequently Asked Questions
What happens if I plug a 30-amp RV into a 50-amp pedestal?
Your RV will work fine. The 30-amp inlet accepts the larger 50-amp plug with an adapter. You will draw only what your RV needs (up to 30 amps), so there is no risk of overload. The adapter is inexpensive and worth carrying.
Can I leave my tanks open while parked at a site?
You can leave the gray water valve open — it drains continuously and does not cause problems. Always keep the black water valve closed until the tank is full. Leaving it open allows solids to settle in the hose, which causes clogs and odors.
What water pressure is safe for my RV?
Most RV plumbing is rated for 40 to 60 PSI. Pressure above 80 PSI can damage fittings and hoses. A pressure regulator keeps incoming water below 60 PSI and costs $15 to $30 — much less than repairing burst pipes.
Do I need to winterize my RV if I am staying connected all winter?
If you are staying connected and the park does not freeze, you do not need to winterize. If temperatures drop below freezing, drain your fresh water tank and all plumbing lines, and use RV antifreeze in the gray and black tanks. Your RV manual explains the process.
What is the difference between rigid and flexible sewer hose?
Rigid hose (PVC) is durable and does not kink, but it is bulky to store and harder to connect. Flexible hose is compact and straightforward to store, but it can kink and is more prone to damage. Most RVers use flexible hose for convenience, but rigid hose lasts longer if you have storage space.
