Learn how to replace the water tank on your DREO RO Water Filter 112 or 114. Simple steps, common mistakes, and practical tips for a mess-free refill.

Quick Answer

To replace the water tank on your DREO RO Water Filter 112 or 114, simply remove the old tank, clean the base, and snap the new 0.8-gallon tank into place. No tools are needed, and the whole process takes less than five minutes.

Why Replace the Water Tank?

Over time, the water tank in your RO filter can develop mineral buildup, cracks, or stubborn odors that regular cleaning can't fix. Replacing it restores the clean, fresh taste you expect and prevents leaks that could damage your countertop.

The replacement tank is designed specifically for the DREO Water Filter 112 and 114, so you don't need to worry about fit or compatibility. It's a straightforward swap that keeps your filtration system working as intended.

What to Check Before You Start

Before ordering a replacement, confirm your filter model. The 112 and 114 share the same tank design, but other DREO models (like the 511) use a different pitcher. Check the model number on the back or bottom of your filter to be sure.

Also, inspect the tank for cracks or warping. If the tank is damaged, replacing it now prevents leaks and keeps your water safe. If you're only noticing a taste issue, a full filter replacement might be needed instead.

Step-by-Step Replacement

Remove the Old Tank: Lift the tank straight up and out of the filter base. If it resists, gently rock it side to side. Empty any remaining water into the sink. Check the tank for cracks or mineral buildup before disposing of it.
Clean the Filter Base: Wipe the inside of the base with a soft, damp cloth to remove dust or debris. Do not immerse the base in water. Make sure the base is completely dry before placing the new tank.
Prepare the New Tank: Rinse the new tank with cold water. Do not use soap or detergent, as residues can affect taste. If the tank has a sticker, remove it completely before use.
Place the New Tank: Align the tank with the opening in the filter base and lower it straight down until it sits flush. It should not wobble. If the tank doesn't sit level, remove and reposition it rather than forcing it.
Refill and Test: Fill the tank with fresh water, replace the lid, and run a cycle. Check for leaks around the base and confirm the water flows through the filter. If you notice a leak, reseat the tank or contact support; do not use the filter until it's resolved.
