## Overview

The Camco RV Water Tank Filler with Shutoff Valve is a compact, efficient accessory that speeds up water tank filling by using a large 5/8" tube for near full-pressure flow while minimizing backflow. Its quarter-turn valve offers precise water flow control, enabling solo operation and preventing spills. Certified low lead and compliant with federal and state regulations, this device is a must-have for hassle-free RV water management.

## Description

Camco RV Water Tank Filler with Shutoff Valve helps fill your water tank in a fraction of the usual time and eliminate “bubble-back.“ Large 5/8" fill tube allows you to fill your camper, trailer or motorhome water tank at or near full pressure while minimizing line backflow. Quarter-turn pressure-sealed valve allows you to selectively control water flow.

Review: More useful than I first thought - This is a very simple but very useful device that does its job and does it well. It's an attachment to a water hose that helps you fill a water tank via a "gravity fill" (i.e. non-pressurized) port. It does two things: (1) extends the hose into the pipe behind the gravity fill port, reducing spills, and (2) provides a useful valve to regulate and stop the water flow once your tank is full. It does both well; I have no complaints. This device isn't strictly necessary for filling your water tank, and I originally didn't think I'd need it. But now that it's solved the problems it's designed for, I can't imagine going back to life without it. For example, filling our water tank used to be a two-person job: one person to hold the hose to the fill port and watch for overflow, and another to hover over the water spigot (which might be some distance away) and be ready to turn it off at a moment's notice. Now the water flow can be turned off quickly via this device's valve, and we no longer need that second person.
Review: Works Great! - It works, what else to say. Careful though, its plastic and can easily break.

## Questions & Answers

**Q: Under what circumstances would you need this device instead of just attaching your water hose to the RV water inlet?**
A: You may not. The only advantage is that this device has a shut off valve which is very handy for me. But the clear vinyl hose has a larger diameter than the inside of the water inlet on my RV. I had to find a smaller diameter vinyl hose to attach to the filler hose and use a small hose clamp to secure them together. It may fit your inlet on your RV but it was too large for mine.

**Q: Is this safe for potable water?**
A: I use this filler to fill my fresh water tank.  It is as safe as the water you use.  I do make sure it is completely dry before I store it until the next use.

**Q: Can this be used to pull water from a 5 gal bucket using a pump attached to the rv fresh water hose? so water bucket, camco tube, pump, rv hose, rv?**
A: Probably not. It is designed to filter the water from a water bib [faucet] and remove some contaminents as the water enters the RV supply hookup. I doubt you can pull water through it using an RV pump. You can fill your fresh water tank from a water bib and use the filter before the water enters the holding tank. They your RV pump will pull the water through the RV system.

**Q: Is it very bendable?**
A: Yes  firm  but bendable. attaches to end of water hose . Inset plastic tube into filler hole  turn on water . You do not need to stand there holding hose while your tanks fill.
