How do I keep my RV’s plumbing system running smoothly?

Regular maintenance is key! For your freshwater system, use a water filter to keep everything clean and free of contaminants. Adding a water pressure regulator is a good idea too—it protects your pipes when you’re hooking up to different water sources. For the sewer side of things, using tank treatments can help break down waste and keep odors in check. And don’t forget to check your hoses and fittings for leaks or wear now and then.

What should I look for when buying a sewer hose?

You’ll want something long enough to reach dump stations—15 to 20 feet is usually a safe bet. Look for durable materials that can handle regular use without puncturing, and make sure it’s easy to store. Collapsible hoses or ones with storage bags are super handy for keeping things tidy.

How can I make sure the water in my RV is safe to drink?

First, use a drinking water hose that’s made specifically for potable water—don’t use a garden hose! Add a good water filter to improve taste and remove contaminants. And when you’re connecting to an outside water source, a water pressure regulator will protect your system from damage caused by high water pressure.

Do I need special fittings for my RV’s water system?

It’s a good idea to have the right fittings on hand. Things like hose adapters, elbows, and couplers make connecting everything a lot easier. If you want to save time at the campsite, quick-connect fittings are super convenient, too. Just make sure the fittings match your hose diameter and material.

How do I winterize my RV’s plumbing?

Winterizing is a must if you’re storing your RV in cold weather. Start by draining all the water out of the system, including the water heater and tanks. Then, use a water pump converter kit to run RV-specific antifreeze through your plumbing. Turn on all your faucets, showers, and toilets until you see the antifreeze come through, and pour some down the drains to protect the P-traps. It’s not hard, and it’ll save you from costly repairs later.

What is a tankless water heater, and why should I consider one for my RV?

A tankless water heater heats water on demand, meaning you only use energy when you need hot water. Unlike traditional water heaters that store hot water in a tank, these units provide a continuous flow, so you’ll never run out. They’re also compact and energy-efficient, making them a great choice for RVs where space and efficiency matter.

Many RVers switch to tankless systems for their convenience and efficiency. Just make sure the unit fits your existing space and matches your RV’s plumbing and power setup. Some units may require slight modifications during installation, so check the instructions or consult a professional if needed. For a complete guide, check out our article.
