Installation Overview
InSinkErator instant hot water dispensers require a standard 1.375-inch diameter mounting hole, which this template provides with precision accuracy. The 4.0-inch clearance diameter marked on the template indicates the minimum unobstructed zone required beneath the countertop surface for proper installation of the mounting assembly, supply lines, and connection hardware. When planning the installation, position the dispenser within comfortable reach of the primary sink workspace, typically 2-3 inches from the sink rim edge. Verify that the selected location provides adequate clearance below for the hot water tank - InSinkErator tanks range from compact 1/3-gallon models (HOT1) requiring about 10 inches of vertical space, to larger 2/3-gallon tanks (H770, HC1100 systems) needing 12-14 inches. The tank should be mounted within 16 inches of the dispenser connection point and requires access to a grounded 115-volt electrical outlet. InSinkErator systems are pre-set to 200°F at the factory and require minimum 30 psi water pressure for optimal performance. Always confirm the specific model's requirements before cutting, as some newer models may have slight variations in mounting hardware.
CNC Cutting Notes
Load this DXF template into your CNC programming software and verify the 1.375-inch hole diameter is correctly scaled before generating toolpaths. InSinkErator dispensers use this standardized hole size across most product lines, making this template universally applicable for the brand. For CNC operations on natural stone, select a 1.375-inch (35mm) diamond core bit and ensure it's properly dressed and cooled throughout the cutting cycle. Program the machine to cut from the top (finished) surface down to achieve the cleanest edge where the dispenser escutcheon will sit - this is critical for InSinkErator's sleek designs where the base plate sits flush against the deck. Set cutting parameters conservatively: for granite, use 2-3 inches per minute feed rate with constant coolant flow; for engineered quartz, reduce to 1.5-2 inches per minute as these materials are harder and more brittle. Ensure complete penetration through the material thickness plus 2-3mm to guarantee a clean through-hole. The 4.0-inch clearance circle is a reference zone indicating required clear space beneath the deck - do not cut this circle. When nesting multiple templates on a slab, maintain at least 8 inches center-to-center spacing between holes to preserve structural integrity. For manual cutting operations, use the template to precisely mark the center point, drill a pilot hole, then core out the final 1.375-inch hole using a diamond hole saw with guide bit.
Material Compatibility
This InSinkErator template is fully compatible with all countertop materials commonly used in residential and commercial applications including granite, marble, engineered quartz (Silestone, Caesarstone, Cambria, HanStone), natural quartzite, soapstone, solid surface (Corian, Hi-Macs, Staron), and ultra-compact surfaces (Dekton, Neolith, Lapitec). The 1.375-inch hole diameter provides excellent structural support while accommodating InSinkErator's quality mounting hardware. For standard 3cm (1.25-inch) thick materials, no additional reinforcement is typically required when the hole is properly positioned away from edges and stress points. In 2cm installations, consider adding epoxy backing plates or support washers to prevent flexing under the weight of the dispenser and during use. Natural stone materials cut cleanly with diamond core bits - always use water cooling to prevent thermal shock and microfracturing. Solid surface materials are more forgiving and can be cut with carbide tooling, with edges easily polished to match the surface finish. When working with ultra-compact porcelain surfaces, use specialized diamond core bits rated for maximum hardness materials and reduce feed rates by 30-40% to prevent chipping. For exotic materials like semi-precious stone, backlit onyx, or ultra-thin porcelain panels, consult the material manufacturer regarding minimum edge distances and reinforcement - typically maintain at least 4 inches from any edge, seam, or other penetration.
Where to Buy
InSinkErator instant hot water dispensers compatible with this 1.375-inch template are widely available through home improvement retailers (Home Depot, Lowe's), plumbing supply houses, kitchen and bath showrooms, and online retailers. Popular models include the Indulge Contemporary (F-HC1100 series), Indulge Modern, HOT1 (compact), HOT250, H770 (2/3 gallon), and combination hot-cold systems. When purchasing, verify the model number includes the mounting hardware and confirm compatibility with this standard 1.375-inch hole - most InSinkErator dispensers use this size, but always check the specification sheet. Complete systems typically include the dispenser faucet in various finishes (chrome, brushed nickel, oil-rubbed bronze, stainless steel) and require a separate hot water tank. Tank options include the compact HOT1 tank (1/3 gallon, ideal for light use), the standard H770 tank (2/3 gallon, most popular for family homes), and the high-capacity HOTTAP (5/8 gallon instant systems). Many systems offer optional filtration components for improved water quality. Professional fabricators should recommend clients have the actual InSinkErator unit on-site during templating to verify finish, handle configuration, and exact mounting requirements. Pricing varies by model and finish, with faucet units typically ranging from $180-$450, and tanks adding $200-$400 depending on capacity and features.
