A hot water circulation pump can make a morning shower much more pleasant. You won’t have to wait for the water to heat up before you jump in and soap yourself. That wait, which can seem endless when the weather is bitter and wintry, occurs because the hot water has to travel all the way from the hot water tank to the shower. A hot water circulation pump gives you hot water where you need it, when you need it, without any waiting. It's something to benefit all homes.

Step 1 - Location for the Pump

You will find that a new circulation pump will be most effective if you fitting it to the plumbing fixture that’s furthest from the hot water tank in your house. It doesn’t matter what type of fixture this is and it could be a shower or a sink. Find the best location and select a suitable place alongside it for the circulation pump.

Step 2 - Attaching the Pump

First, turn off the water at the house main and follow up by turning off the water to the fixture to which you’ll be attaching the circulation pump. Drain the water from the fixture.

Next, you may need to attach the pump to the wall. Use a stud finder to locate the studs on the wall and mark off your drilling points with a pencil. Now, use a level to ensure the pump is straight and make any necessary adjustments to the appropriate guide marks before drilling, ensuring the holes go through to a stud. Drill the holes and set in the screws to secure the pump into position.

To connect the circulation pump, use the tubing that comes supplied with it. This will be either copper or stainless steel tubing. The lines will connect to the hot water line of the fixture and there is hardly any plumbing involved. Disconnect the hot water line from the fixture then reconnect according to the instructions that came with the circulation pump. The lines will connect using nuts and washers so the only tool you will need to accomplish this is a wrench. Apply Teflon tape to the threads before tightening the nuts and ensure a tight fit is established to prevent water seepage.

Step 3 - Fitting the Control Board

The control board lets you set a timer for the circulation pump so you’re not producing hot water when you don’t need it. This will save you money on your energy bills. It’s best to have the control board close to the pump but it will need to be attached to a stud to make it secure on the wall.

Use the stud finder again to locate the studs and mark them off. Use your level to ensure your control board is straight with the holes for installation set in line against the studs. You should be able to screw the unit directly to the wall without drilling first. Connect the control box to the pump using the wire with the pump kit and following the manufacturer’s instructions.

Now, turn on the water to the fixture and turn the water back on at the house mains. Turn on the shower and you should have instant hot water which will be ready for you to relax in.
