20 Gallon Metal Reverse Osmosis Tank

This 20 gallon tank is manufactured specifically for reverse osmosis water using the finest FDA approve materials. The water chamber is made with a virgin polypropylene line, a high-grade Chlorobutyl diaphragm and the patented stainless steel water connection. Additionally, every diaphragm is “post cured” to remove any harmful materials or chemicals prior to being assembled, which ensures that you will have tasteless, odorless and contaminant-free water.

When it comes to structural integrity, deep drawn steel domes and precision weld seams give this tank unparalleled reliability and every tank is tested for integrity. This tank is maintenance-free because of the sealed brass air valve and o-ring sealed air valve caps. Once you install it and check that the air pressure is 5-7 pounds, you should never have to touch it again.
