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. 
                                 
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.  |
