Installation instructions for Pentwater Farmhouse Sink

Installation instructions for Pentwater Farmhouse Sink
General Recommendations:
Please read installation and maintenance instructions thoroughly.
Inspect your sink for any noticeable damage before installation.
Check all local applicable plumbing and building codes.
These instructions are based on application to composite material or solid surface countertop
installation only; countertop application to stone, marble, granite or butcher-block should be
referred to an experienced countertop fabricator for custom installation.
Farmhouse sinks are individually hand-crafted and Pentwater suggests using experienced and
professional installers only. For custom cutting of countertop and installation of the actual sink,
on-site installation is also recommended. Acceptable variances are approximately 1/8 of an
inch. Alignment to the cut-out and precise application and trimming of any adhesive sealant are
critical to a superior fit and finished look. Please take extra care in this regard.
Farmhouse sinks require custom order cabinets.
Pentwater does not accept any liability for damage to countertop, sink fixture, faucets, or
personal injury during installation. Warranty is void if installation instructions are not followed.

Installation Options:
Farmhouse sinks offer installation options depending on your design.
Under mount Installation
Flush mount Installation
Built-up Installation
Caution: All installation types need to allow room for faucet installation. Ensure adequate
clearance behind the sink for any faucet and backsplash, as well as full range of motion for
faucet spouts and handles.
Typical flush mount and built-up installation
Built-up installation may expose sink sides to be raised up to 1" above the countertop.
1. Prepare the Sink Base Cabinet
Farmhouse sinks require custom order sink base cabinets with a front cutout to accommodate a
10" deep sink. Build a plywood platform on a support frame inside of the sink base cabinet.
Platform must support the weight of the sink and any attachments such as garbage disposals.
When the sink is placed onto a platform, make sure the top of the sink is evenly flush against
the bottom of the countertop. Allow clearance for water supply line and drains or garbage
disposal, as necessary.
2. Make a Template and Cutout
3. Set the Sink
Set the sink on top of the cabinet or into
the cabinet front cutout. Apply sealant if
necessary as a gasket between the sink
and cabinet.
4. Install the Countertop
Depending on the installation option, make
proper cutout of the countertop.
Pentwater recommends a 1/4" reveal on 3
sides when installed under mount style.
For a flush mount or built up installation,
cut countertop along with outside line of
the sink profile. The front end of
Farmhouse sinks is designed to be installed
3/4” extended out beyond the front end of
the countertop.
Cut countertop accordingly. No template is
provided due to the custom nature of each
application and installation.
The actual sink is used as the template
for each installation.
After centering the sink and allowing for any faucets and backsplashes, use a pencil to outline
the sink as your guide for the cutout, allowing for any reveal before the actual cutting.
Carefully clean bottom of countertop and top flange of the sink with denatured alcohol. Apply
bead of silicone adhesive (not supplied) around the top edge of the sink. Place countertop onto
the sink. Remove excess sealant from the lip or any surfaces with a cleaner recommended by
manufacturer of adhesive sealant.
Care and Maintenance
Clean everyday by thoroughly rinsing with a mild soap and warm water and wipe dry.
Rub lightly with a soft cloth in the direction of grain lines on a regular basis for additional
preventive cleaning.
Keep the sink free of any standing water as this can cause a buildup of mineral deposit, which
can affect the appearance of your sink.
Any stubborn stains should be removed by scrubbing in the direction of the grain with a mild
abrasive such as Comet. Always rinse the sink after using any cleaning agent and wipe dry.
Clean any mineral deposits built up over time with a mild solution of vinegar and water followed
by a thorough flushing with water.
Remove any scratches with a Scotch-Brite pad and cleaning agent rubbing in the direction of the
 Leave water spots, steel cookware or utensils in the sink for lengthy periods; iron particles often
develop rust spots in the stainless-steel surface.
Use a steel wool or scoring pad as it damages the sink surface and causes discoloration.
Let household cleaning agents or bleach sit in your sink for long periods of time as this may ruin
the finish of your sink.
Leave rubber mats, sponges, or cleaning pads in the sink overnight as this will trap water and
could stain and discolor the sink surface.
Use any drain cleaning products containing sulfuric or hydrochloric acid as this will attack the
Silver cleaners can also contain acids that will damage the sink surface.
Use the inside of the sink as a cutting surface.
