About Us

Since 1981, Valterra Products, has been a leading supplier of brand name product lines to the RV, pool & spa, and plumbing industries.

In 1971 Bert Grengs started Grentec Inc., a plastic injection molding company in Burbank, CA. They began manufacturing RV gate valves, RV toilets, plumbing fittings and later some of Southern California’s iconic plastic skateboards like the “banana board”.

In 1981 Bert retired and Valterra Products, Inc. began with his son, George Grengs, daughter-in-law, Patricia Grengs, daughter, Barbara Glennon, and son-in-law, Dennis Lunder owning the new company.

Although the RV products were the primary business they reintroduced a skateboard line in 1984 that focused on wood decks, exciting graphics and precision bearings.

In 1985 Michael J. Fox rode a Valterra skateboard in the movie “Back to the Future” which introduced Valterra skateboards to the whole nation.

Eventually Valterra moved away from the skateboard business and focused on the expansion of their RV business with the acquisition of many important product lines including sewer hoses, RV locks, Fridgemate Fans, and ABS tanks.

The main gate valve product line continued to grow as the line expanded into pool & spa, plumbing and industrial applications.

Valterra acquired the Blue Devil Pool & Spa Accessories line in 2002 which expanded the pool & spa assortment beyond plumbing to a full line of Blue Devil maintenance accessories.

The line specializes in pool water test kits, reagents, valves, vacuums, brushes, nets, and poles for use by consumers and pool service professionals.

In 2008 Valterra established a contract manufacturing division to offer low-cost custom manufacturing and assembly services to client companies seeking to reduce costs and improve the bottom line. A year later, Valterra joined C-TPAT (Customs - Trade Partnership Against Terrorism).

With 39 injection molding machines, 3 profile extrusion machines, JIT (just in time) warehousing with a global supply chain, prototyping, bottling, assembly and packaging, Valterra can handle a multitude of contract manufacturing projects. Our molding facility became ISO 9001:2008 (International Standards for Quality Management System) certified in 2015.

In 2013, Valterra management successfully completed a corporate restructure and recapitalization.  This has assisted Valterra in acquiring several leading brand companies to round out product offerings in the RV, truck and motor coach markets.

The recent acquisitions include Mighty Cord, Phoenix Faucets, Odorlos eco-friendly tank treatments, Diamond LED lights, GoPower! solar systems, Minder Industries tire pressure monitoring and Monochem deodorizers and cleaning products.

Valterra has, through organic growth and strategic acquisitions become one of the premier RV suppliers in North America serving both the RV OEM and RV Aftermarket.

Though Valterra has grown through the years, the company continues to operate as a family business with many of the employees having worked here for 20, 30, even 40+ years!

With 430+ employees and 160,000 square feet of production, warehousing, and shipping space, the Valterra team is here to help with all your RV, pool & spa, plumbing, industrial and custom manufacturing needs.
