Installing a Cast Iron Sink Installing a Cast Iron Sink
Having a cast iron sink is a thing of beauty, thanks to its designer look. It is also strong and durable, and unlike stainless steel it comes in many colors, making it suitable for the bathroom as well as the kitchen. This article shows how to install one. Since sinks are heavy, lifting the cast iron sink into place can be a tough task. It is suggested to get a friend to help you.
Step 1 – Measure the Sink
Use the template that came with the cast iron sink to make the proper cutout in the counter. If there isn’t a template, measure the sink and create one from scratch. Make sure the counter is suitable to carry the weight of the sink.
Step 2 – Install Basket Strainer
It is best to install the basket strainer and faucet before installing the sink. Mount the basket strainer first. Remove dust and debris from the drain hole with a damp cloth in order to ensure a good seal. Apply a generous amount of plumber’s putty the underneath of the basket and push it into place. From under the sink, put the large rubber washer over the exposed thread followed by a second thinner washer (all this will have come with the basket strainer). Screw the large metal nut onto the thread. As it becomes fully tightened the putty will ooze out, which will need to be cleaned immediately with a cloth.
Next, the faucet will need to be installed by following the manufacturer’s instructions in order to comply with the manufacturer’s terms and conditions. The installation process varies for each brand.
Step 2 – Installation of Cast Iron Sink
To install the cast iron sink turn it upside down while protecting its top surface from damage (also protect the sink and basket strainer if they have already been installed). Squeeze some silicone sealant around the edge of the sink and ease the sink into the cutout in a centered position until it is in contact with the counter. Begin the process of removing the excess sealant to complete the installation. Once the excess sealant has been removed allow it to fully dry—one full day should be sufficient. Excess sealant is difficult to take off if not removed before it dries.
Step 3 – Connect the Sink to the Plumbing
Next, connect the cast iron sink to the pipes and drain. Connect the drain tailpiece to the basket strainer. Use the pipe cutter to trim the ends of the hot and cold pipes. Join them to the faucet using the manufacturer’s instructions.
Step 4 – Check Faucet and Drain Connections
Turn on the main water supply and open the faucet shut-off valves. Check carefully for leaks. If there are any, you may have to retighten everything you installed. Usually, little more than a quarter turn is needed. The cast iron sink project is now complete.
