Dead Level™ Pre-sloped Trench Drain System - Watts Water ...

Dead Level Trench DrainsHow many feet should I runQ: Q:before adding an outlet?An outlet every 100' (30m) is sufficient in most applications.If there are specific concerns over flow rate orA:volume, consult the Dead Level Flow Rate Chart.A:Does my system have to beQ:Q:sloped? Can I use all neutralchannels?Neutral trench runs are frequently installed where theA:ground is already pitched, or where depth constraintsA:restrict the use of deeper channel sections.If I use neutral channels, willQ: there be drainage problems?Q:Unless there are specific flow velocity requirements (ex.airport runways), neutral channels will not significantlyA:affect drainage. Even a system comprised of all neutralchannels, on a level grade, will drain to the outlet. However, flowthrough a sloped system does help flush debris, and keep the channelsclean.A:Is Dead Level available 12"Q: (305mm) wide, or with curved Q:sections?New 12" wide Dead Level DX is now available. WeA:A:do not make curved sections or “sport track”.What’s the difference betweenQ:Q:polypropylene (PP) and high-densitypolyethylene (HDPE) channels?A:PP & HDPE are similar compounds, which can be freelyinterchanged in all common trench drain applications.If high concentrations of chemical substancesA:are anticipated, specific PP & HDPE chemical resistance chartsshould be referenced.Q:Can I comply with an H20 LoadQ: Rating?A:We show H20 as the symbol for water – it should beA:H20, as in the number twenty.Q:What is the maximum temperatureQ: of water that can be dischargedinto the system? A:Water up to 212°F (100°C) has a negligible effect onA: polypropylene channels.How much time and labor shouldI figure for installation?A two-man crew with rebar driver and laser level caneasily set 100' (30m) in a day.How much field cutting isrequired?Cutting is required only to open outlets, trim end caps,and make catch basin or tee connections. StandardDead Level sections are 4' (122cm) , but odd runs areaccommodated with 1', 2', and 3' (30, 61 and 91cm) sections.For specifications in increments of less than 1' (30cm), the runcan almost always be extended or shortened to the nearest foot.How much concrete is requiredaround the drain? Can I installDead Level in asphalt, or anything otherthan concrete?Concrete should be poured minimum 4" (102mm)around the entire trench system. Dead Level shouldnot be installed in anything other than concrete.What size rebar do I need?#4 rebar - 1 /2" (13mm) diameter.Should I install the grates beforethe pour?Grates should be installed before the pour.Construction covers supplied with Dead Level protectthe grates, and keep debris from entering thechannels.Do I have to seal the channeljoints?Channel joints are not sealed in most applications.If there is a special requirement, joints can be sealedwith a bead of silicone caulk.How do I remove theoutlet and catch basin cutouts?Outlet cutouts can be removed with a 4" (102mm) or6" (152mm) hole saw, or with a reciprocating saw.Use a reciprocating saw for catch basin cutouts.A Watts Water Technologies CompanyS-WD-DeadLevelFAQ 1221USA: 100 Watts Road, Spindale, NC, 28160-2298; www.watts.comCanada: 5435 North Service Rd., Burlington, ON, L7L 5H7; www.wattscanada.ca© 2012 Watts
