Valterra Hydroflush 45° sewer tank rinsing attachment, clear bayonet-fit with removable anti-siphon valve

The Valterra 45° Hydroflush (F02-4100) is a clear, bayonet-fit sewer tank rinsing attachment with a removable anti-siphon valve that helps flush and break up solids for easier RV, camper, and trailer draining.

If you maintain an RV, camper, or trailer, an efficient sewer tank rinsing tool makes tank cleanouts faster and more sanitary. The Valterra Hydroflush is built with durable clear material, fits standard bayonet connections, and includes an internal backflow preventer so you can rinse without risking contamination of your fresh water supply. Its 45-degree shape and pre-installed fittings create a snug, leak-resistant connection so water is directed where you need it.

How does the Hydroflush improve tank cleanouts?

The Hydroflush directs high‑velocity water into the tank to dislodge solids and wash residue from walls, pipes, valves, and the drain hose. Because you can see flow through the clear housing, it's easy to tell when the rinse runs clear.

• Angled nozzle targets hard-to-reach corners and baffles.
• Clear body provides visual confirmation of clean water return.
• Water stream helps break up and flush away compacted material.
• Works with standard RV sewer hose setups for quick connection.

Will this device protect my fresh water from backflow?

Yes. The Hydroflush includes an internal anti-siphon/backflow preventer that helps stop wastewater from siphoning back into the potable water line. The valve is removable for servicing or replacement when needed.

• Internal backflow preventer reduces contamination risk.
• Removable anti-siphon valve simplifies maintenance and replacements.
• Designed for compatibility with common RV water fittings.
• No special tools required for valve removal.

How easy is it to install and get leak-free performance?

Installation is straightforward: the Hydroflush uses bayonet-style fittings that lock securely to standard sewer hose connectors. Pre-installed fittings and a tight seating design minimize leaks so you can run a robust rinse without wasting water or making a mess.

• Bayonet attachments provide a secure, quick connection.
• Pre-installed fittings eliminate guesswork during setup.
• 45° angle simplifies positioning at dump stations or hose ends.
• Durable materials resist cracking and abrasion from regular use.

What maintenance or care does the Hydroflush need?

Maintenance is minimal: rinse the attachment after use, periodically inspect the removable anti-siphon valve, and replace it if worn. Storing the unit out of prolonged UV exposure will extend its service life.

• Flush with clean water after each use to remove debris.
• Inspect seals and valve for wear before long trips.
• Replace removable anti-siphon valve if it shows damage.
• Store indoors or shaded to preserve clear housing integrity.

Who is this for: The Valterra 45 Degree Hydroflush F02-4100 is designed for RVers, campers, and trailer owners who want a faster, more reliable way to rinse sewer tanks and hoses. It's ideal for frequent travelers, rental fleet managers, and anyone who performs routine septic maintenance and prefers a visible, secure connection with built-in backflow protection.
