Sewer and Water Gear for Your First Camper Season

The part nobody demonstrates at the dealership

Two systems share this section because they share a workflow: at every site you connect fresh water in and, at some point, you send waste water out. Done correctly the sewer job takes ten minutes and you never think about it again. Done badly it becomes the story you tell for years, and the difference is almost entirely about having the right four items and doing them in the right order.

The fresh water side is less dramatic and more expensive to get wrong. Campground water pressure is unregulated and varies enormously between sites; RV plumbing is not built for the top of that range. A burst line inside a wall is a repair you cannot see happening.

What to buy first

Four things, and they are all cheap: a 20-foot sewer hose, a clear elbow so you can see when the tank is actually empty, a pressure regulator, and a drinking-water hose. Add disposable gloves, which cost almost nothing and which you will not want to be without.

On length: fifteen feet reaches most sites, twenty reaches nearly all of them, and a 10-foot hose will eventually strand you with no workaround available. That question is worth settling properly — what size sewer hose you need.

How the category divides

On the waste side: the hose itself, a support so the run falls downhill the whole way, and tank treatment to keep things breaking down between dumps. On a site with no sewer connection at all, add a portable waste tank so a week-long stay does not end at the sink.

On the fresh side: a pressure regulator (protection), a drinking-water hose (safety — a garden hose is not rated for this), and a filter (taste, and optional on a first trip).

What decides price

For hoses, wall construction and fitting quality. A cheap hose is thin-walled and its fittings are the part that fails — usually at the worst possible moment. Upgrading here is the most commonly recommended first upgrade for a reason, and the direct comparison shows exactly what the extra money buys.

For regulators, adjustability. A cheap plastic inline regulator sets a fixed low pressure and reduces your flow to a trickle, which is why people remove them and then forget to put them back. An adjustable brass one holds a usable pressure and stays installed, which makes it the one that actually protects you.

The mistake first-season buyers make

Leaving the black tank valve open on a full-hookup site. It seems sensible — why not let it drain continuously? Because the liquid leaves and the solids stay, drying into a mass around the tank sensors that is genuinely difficult to clear. Keep both valves closed and dump when the tank is nearly full, so there is enough volume to carry everything out.
