RAINES™ Stainless Steel PEX Fittings

RAINES™ Stainless Steel PEX Fittings

In 2014 we were the first to introduce crimp type Stainless Steel PEX Fittings to America. Others try to make that claim, but we were, now and will be providing innovative high quality PEX fittings and significantly good prices.

Now in 2021 we are pleased to expand our RAINES™ PEX offerings to 7 styles in sizes 3/4” and 1”. All RAINES™ PEX Fittings are manufactured with beautiful high quality 316 Stainless Steel to maintain purity of water and provide longevity to your rainwater collection system.

These RAINES™ PEX Fittings include new design innovations that will make them more practical, reliable and a joy to work with.

Walrus Pump HQ800H

PUMPS We offer the Walrus HQ800H 1hp, but we can special order all Walrus models. It is a very good on-demand pump and can also work with a pressure tank to prolong pump life. Please read technical data: Walrus Pump Technical Data.pdf

BASIC SYSTEM  Our approach is ‘keep it simple’

  • Dry System piping from gutter into tank with First Flush
  • Begin with one 2500 or 3000 gallon polyethylene tank.
  • Polypropylene valve/SS nipple, then flexible connection to polyethylene pipe to pump
  • Flexible pump SS connectors lead to garden, or to house with filters and UV unit
Enduraplas Water Tanks

TANKS We like either the 2500 gallon or 3000 gallon tanks as they are the most cost effective. As your system grows, these tanks can be chained together. Also, they can easily be handled by two people… no cranes. The height of the tank should be a foot below the gutter level.
