Pipe Sealant

A widespread bathroom faucet offers a choice of hot or cold water coming out of the faucet. This type of faucet has two handles, which are typically 6-inches apart. The distance can also be adjusted up to 12-inches. The two handles are used to choose between hot or cold water to come out of the faucet.  This bathroom faucet configuration is perfect for bathroom sinks that have three holes, one for the spout and two for the handles. Here is a guide to installing a widespread bathroom faucet.

Step 1 – Preparation

Make sure that the water supply that provides water for the bathroom is shut off. Check the pipes that lead to the bathroom and see if there is any damage. Leaks need to be repaired first in order to ensure that all the water from the source goes directly to the faucets. If there are any water leaks in the plumbing system, make use of a pipe sealant to repair them. If the installation is to be done on an old sink, make certain to remove the putty from the previous installation.

Step 2 – Install the Spout Shank

Before installing the spout, apply a generous amount of putty on the underside of the spout. If the package comes with a putty plate, apply it on the plate according to the manufacturer’s instruction. Insert the spout into the center hole. Insert the metal washer as well as the nut through the spout shank and hand-tighten the nut. To secure the spout in place firmly, use an adjustable wrench on the nut. Remove the extra putty that comes out as a result of the tightening.

For thin stainless steel lavatories, it is necessary to insert the dished washer though the spout shank first before inserting the washer and the nut. Once the three are inserted, tighten the nut using an adjustable wrench, but make sure not to tighten it excessively. 

Step 3 - Install the Hot and Cold Water Valves

One of the valves is intended for cold water. It is usually marked blue by the manufacturer for guidance. The “cold” valve should be installed to the right of the widespread bathroom faucet. Insert the body of the “cold” valve into the right hole of on the sink and apply a sufficient amount of putty on the underside of the valve. Insert the washer and the nut through the valve’s tubing. Next, rotate the body of the valve until the copper tubing faces to the outside of the sink. Tighten the nut until the valve is secured in place.

For the “hot” valve, make sure to insert it on the left mounting hole. Follow the same steps as that of the “cold” valve. Once the valves are in place, make sure that the nuts are tightened well enough but not too much. After tightening, remove any excess putty.
