Will this tank fit my RV?
This tank is designed as a direct replacement for RVs originally equipped with Elkhart Plastics part numbers EPI 3472, W1398000, or Myers 221011-2. Verify your existing tank's dimensions (54x32x5.75 inches) and part numbers before ordering to ensure proper fitment.
What fittings or connections does this tank include?
Tank fittings and configurations vary by model. Please verify your existing tank's fitting locations and sizes before ordering. Additional fittings, adapters, or plumbing components may need to be ordered separately or transferred from your existing tank.
How much does this tank weigh when full?
The empty tank weighs approximately 76 lbs. When filled to capacity with 36 gallons of water, the total weight is approximately 376 lbs (36 gallons x 8.34 lbs per gallon + 76 lbs tank weight). Ensure your RV's mounting system can support this weight.
Can I install this tank myself?
Installation requires basic RV plumbing knowledge and appropriate tools. If you're comfortable with RV maintenance and have experience with plumbing connections, you can likely complete this installation yourself. However, professional installation is recommended if you're unsure about any aspect of the process.
How do I sanitize my new fresh water tank?
Before first use, sanitize the tank using a solution of 1/4 cup household bleach per 15 gallons of water capacity. Fill the tank with this solution, let it sit for at least 4 hours, then drain completely and flush with fresh water until the chlorine smell is gone. Repeat sanitization at least twice per year.
What's the difference between this and a holding tank?
