Decide if the Back U-Bracket is the right replacement for your WaterPORT Day Tank mount, with fit checks, installation rules, and compatibility guidance.
Quick answer
Buy the Back U-Bracket only if your WaterPORT 4 Gallon Day Tank's existing bracket is damaged or missing and you need to reconnect the tank to its mount plate. It is a direct replacement part, not a universal adapter for other tanks or racks.
A replacement part, not an upgrade
The Back U-Bracket is the specific bracket that mounts to the WaterPORT 4 Gallon Day Tank and then slots into the mount plate. If your tank and plate are intact, you do not need this part. If the bracket is bent, cracked, or lost, replacing it restores the original mounting interface without changing how the tank attaches.
Because it is a replacement component, the bracket does not add new mounting positions or increase load capacity. Treat it as a repair item that returns your setup to its intended configuration.
Fit depends on the Day Tank and mount plate you already own
The bracket is designed for the WaterPORT 4 Gallon Day Tank and the matching mount plate. It is not listed as compatible with other WaterPORT tanks, third-party plates, or improvised brackets. Before ordering, confirm that your tank is the 4 Gallon Day Tank and that you are using the original mount plate.
If you are building a new mounting system from scratch, this bracket alone will not solve the problem. You need the correct tank and plate first; the Back U-Bracket simply connects the two.
When a repair makes more sense than replacing the whole setup
If only the bracket is damaged, replacing it is the lowest-cost way to keep using your existing tank and plate. Replacing the entire tank or plate is unnecessary unless those parts are also damaged. However, if the mount plate itself is cracked or the tank body is leaking, a new bracket will not fix those issues.
Inspect the bracket and plate together before ordering. A bracket that looks fine but sits loose may indicate a worn plate or missing hardware, not a bracket defect.
Decision rules for buying the Back U-Bracket
- Your bracket is damaged or missing: Order the Back U-Bracket if your WaterPORT 4 Gallon Day Tank's bracket is cracked, bent, or lost and the tank and mount plate are otherwise in good condition. Check the mount plate for cracks before ordering; a new bracket will not fix a damaged plate.
- You own a different WaterPORT tank: Do not buy this bracket if your tank is not the 4 Gallon Day Tank. The catalog lists it only for that tank, and no compatibility with other models is stated. Confirm your tank model before purchase; this bracket is not a universal fit.
- You need a new mounting solution: If you do not already have the matching mount plate, this bracket alone will not let you mount the tank. You need the full tank-and-plate system first. The bracket is a connector, not a stand-alone mount.
- You are unsure about fit: When in doubt, compare your existing bracket shape and mounting points to the product images. If your bracket looks different, contact support before ordering. A visual match is the simplest pre-purchase check.
Product facts
- Back U-Bracket: The Back U-Bracket mounts to the WaterPORT 4 Gallon Day Tank and slots into the mount plate. This tells you the bracket is specific to that tank-and-plate pairing, so it will not adapt other tanks or racks.
