HISTORY

Having the highest degree of experience and actual first hand knowledge of what did not work compelled  a challenge for product development as well as negating possible personal financial liability that could ensue for selling a failed system.  Dallas Drain Company, Inc. purposely devoted a substantial portion of funding and personal involvement in developing French drain pipe.  Our general clientele became a  laboratory of study with actual situations not available in any other formal forum study.  The key need appeared to be the seemingly impossible task of developing a "filter free" perforated French pipe.  However, Ralph’s plumbing experience provided examples of  pipe systems that would flush waste materials from water closets and sink garbage disposals without stoppage problems. A similar style of smooth bore piping and special slotting process developed into a patented "filter free" product,   certainly a revolution in mechanisms dependent on filters which always require cleaning or replacement.  The service requirements in air conditioning and  vehicle oil systems etc is wearisome but allows access for changing filters.  French drain filter material cannot be cleaned or changed since cost would be equal to new installation.
