Video Transcript: How to Install HotLine Internal Sewer Pipe Heaters

Hello, my name is Blair Corder, owner of HotLine Internal Pipe Heater Company. Please use these easy instructions to measure and install your HotLine.

Why do sewer pipes freeze? [Gary Watson, Certified HotLine Installer]:

Once you have a low spot, that's the start of your dam. Pretty soon it builds up and you have a blockage.

The HotLine will keep it thawed.

We're going to install a HotLine. We have two clean-outs for the sewer here.

Assuming one goes one way and the other goes the opposite direction, we want to double check to make sure we install the HotLine in the correct clean-out.

Once we verify the correct clean-out, we put our fish tape in the line so we can get a measurement and ensure we order the correct length of HotLine.

If the steel tape goes we know the HotLine will go. If the steel tape doesn't go the HotLine won't go in either.

We're going to hit the main line where the sewer and the main come together and I should be able to feel it very soon.

That's it right there. I can feel it hitting. That's our length, where it stopped.

We'll mark the steel tape with electricians tape and that's the length we need for our HotLine.

Now we will pull the fish tape out and lay it down on the ground straight.

Measure from the end of the fish tape to the electricians tape with a continuous tape measure.

It's 25 feet. Now we know the exact length we need for our HotLine.

When you bump into something, back off a few inches for clearance. The line will not freeze in that inch or two of clearance.

After we get our measurement, we want to prepare our connections for HotLine installation.

Pull the cap off the sewer (if present). Make sure you have a collar so the HotLine has something to screw into.

We will glue the collar into the sewer line so it is permanent.

Use plastic cement primer to clean the sewer line and the collar fittings where they connect.

Apply the glue to the same areas.

Let it sit for 30 seconds and it will be permanent. You can't move it again.

Now we're set up to install our HotLine.

Turn on the hot water in the building to assist the installation.

A helper will help you keep the HotLine straight during insertion. If you kink it, the HotLine may break.

Make the angle of the curvature of the Hotline go the same way the sewer pipe bends.

When the HotLine is fully inserted, make sure the fittings are loose so the cap can be turned into the collar and the HotLine can be positioned correctly.

Hold the HotLine stationary while turning the cap into the collar.

The gray fitting on the cap needs to clamp around the copper sleeve of the HotLine.

The strain relief of the HotLine should point in the direction of your transformer location.

Tighten the gray fitting around the copper sleeve of the HotLine.

Now that the HotLine is installed, our next step is to mount the transformer.

We have a transformer mounted inside a Power Center/Nema4 Weatherproof Cover (an add-on accessory available from HotLine on the Power Center/Nema4 Weatherproof Cover page)

We are mounting the transformer outside so it needs a weatherproof cover for proper operation (crawl space installations may not require a box).

When positioning your transformer box make sure the “pigtail” coming out of the box is long enough to easily connect to the HotLine.

Also, double check to make sure the power cord is set up correctly before plugging the HotLine in.

Mount the transformer to a secure, stable object.

(Note: Every installation is unique. Please call (877) 881-2980 or contact us if you have questions about your specific installation.)

Unscrew the cover from the front of the HotLine box.

Unscrew the strain relief from the back of the HotLine box.

Insert the two wires “pigtail” through the strain relief.

The large wire fits the ground. The smaller wire fits the electrode.

Use 7⁄16″ wrenches to attach white wire to ground. Use a Phillips screw driver and a ⅜″ wrench to attach the black wire to the electrode.

Make sure wires are tight to prevent arcing and heat loss but try not to bend electrode as you could break its insulation and cause it to short out.

Pull wires back out of box so they don’t touch inside the box and screw on the strain relief finger tight.

Tighten up bottom gray nut to bottom of box.

Put cover back on and tighten screws.

Loosen compression fitting and push HotLine down until it stops.

Re-tighten compression fitting.

Tighten O-ring seal.

Mount the transformer box and plug in the transformer.

If the green light on the lower-right side of the box comes on the transformer is working. The HotLine will start getting warm.
