Installing a boiler circulator pump can be accomplished over the course of a weekend with some effort and preparation on your part.
Step 1: Gather Tools Needed for the Boiler Circulator Pump Installation
Purchase a replacement or new boiler circulator pump for your boiler along with the tools listed above. The pump can be purchased from a plumbing supply store or at a local home improvement center.
Step 2: Turn off the Electricity and Locate the Boiler Circulator Pump
To avoid electrocuting yourself turn off the electricity to the boiler before engaging the pump. With the electricity off match the replacement pump. Make sure that the pump matches before proceeding. If it does not match, return it for the correct part to install to your boiler.
Step 3: Remove the Existing Boiler Circulator Pump
Use the plies to remove the existing wires from the pump. You may also need the wrench depending on how the pump is attached to the boiler. With the existing pump removed from the boiler place it in the box of the new pump to be returned to the retailer who recycle core parts.
You will need to be able to catch any water that may leak out of the boiler while you are removing the existing pump assembly. Have plenty of towels available to mop up any water that spills out as you remove the existing pump. Be sure to keep the wires away from any water and dry at all times. If you fail to do this, you may cause a short when you hook up the new circulator pump.
Step 4: Attach the New Boiler Circulator Pump
In the reverse process that you used to remove the existing circulator pump, attach the replacement boiler circulator pump to the boiler. Tighten the hoses and wires using the pliers and wrenches as needed and make sure that the pump is properly seated in place.
Step 5: Turn on Water Supply and Electricity
Turn the water supply on for the boiler and restore the electricity of the pump. Manually start the pump to see if it sounds like it is working properly.
This will complete the installation of your circulator pump to your boiler.
