Intelligence Reports http://www.http://www.repwars.com/rss/rw_updates.xml A single detail on a set of Plumbing Drawings may not be sufficient to address all of the various floor pipe penetrations required in a project. Some penetrations will required sleeves and others may not. All penetrations should be sealed watertight, but some may require sleeves with tops extended above the slab for additional protection at locations where standing water is expected. A Plumbing Engineer should evaluate the various penetration conditions that will be encountered on an individual project and clearly define the requirements that must be met within the Contract Documents. http://www.repwars.com/ Pipe Floor Penetrations RW072708 sUN, 27 Jul 2008 02:30:55 CDT Architects commonly lose control over a design by overlooking plumbing space requirements. A contractor's task is to build based upon an Architect's documents. When walls and chases are not designed to accommodate piping and supports, the contractor will be forced to increase their size. As soon as this occurs, the Architect's dimensions become jeopardized. http://www.repwars.com/193index.html Plumbing Chase Spaces RW071408 Mon, 14 Jul 2008 07:44:12 CDT Plumbing codes are very clear on the relationship between water supply fixture units (fu) and flow in gallons per minute (gpm). On the other hand, they can be confusing to some in regards to the relationship between drainage fixture units (dfu) and gravity flow gpm. http://www.repwars.com/192index.html DFU GPM Conversion RW062408 Sat, 28 Jun 2008 08:50:14 CDT Plumbing design drawings should include more than just the minimum information required to obtain bids and permits. They should also contain data such as capacities, flows, and design intent, to provide the facility's owner with a record that can be used for future troubleshooting and remodeling. http://www.repwars.com/191index.html Plbg Dwgs RW061108 Wed, 11 Jun 2008 09:10:14 CDT Most Plumbing Codes allow solders having a lead content that is more than two percent to be used for joining copper piping in drainage and vent systems. However, no Plumbing Code allows solder having a lead content more than two percent to be used within potable water systems. Plumbing specifications must clarify the solder and flux materials that are acceptable for use in the various piping systems being installed within a project so that the installers and those charged with checking product submittals and inspecting installations will know what is required. -SELECT SOLDER AND FLUX BASICS FROM THE DROP DOWN MENU- http://repwars.com/inreport/irframe.html Solder and Flux RW051208 Mon, 12 May 2008 14:11:52 CDT A leak from drainage piping is never a welcome event and can be unacceptable when it occurs above sensitive areas or equipment. Various codes and regulatory agencies address this issue by limiting or prohibiting the installation of drains above locations where health and safety may be jeopardized. However, most authorities are not always clear on identifying all the areas that they consider as being sensitive, nor are they always clear on specifying acceptable methods for protecting these areas when it is unavoidable or impractical to meet this requirement. This article attempts to address the lack of clarity in existing published regulations and provide recommendations for meeting their intent by providing safe and practical plumbing installations. http://www.repwars.com/IntelligenceReport2.html Drain Leak Protection RW041008 Thu, 10 Apr 2008 08:12:44 CDT This information reflects accepted design considerations based on experience in implementing cross connection control programs and policies set forth by the American Water Works Association, Environmental Protection Agency, USC Foundation for Cross Connection Control and Hydraulic Research and various state and local health departments. These recommendations outline what an acceptable design and installation constitutes and are to be reasonably interpreted. http://repwars.com/RPZBFP.htm BFP Installation RW031408 Fri, 14 Mar 2008 10:10:14 CDT Plumbing Engineers involved with renovation projects are often confronted with floor drains that are no longer required within a building area. A vague note on a drawing simply stating to remove the floor drain does not provide the contractor with enough information to properly perform the work required. http://www.repwars.com/exfd.htm Decommissing Floor Drains RW021108 Mon, 11 Feb 2008 07:30:12 CDT Your knowledge as an Architect is paramount for the success of a project. The profession you chose demands an understanding of all seen and unseen elements within the facilities you design. This knowledge is relied upon, not only by clients, but by the other disciplines helping create your vision. This effort attempts to provide you with basic concepts concerning Plumbing Systems. http://repwars.com/PSP/arch.html Plumbing for Architects RW011108 Fri, 11 Jan 2008 08:22:18 CDT
