Mr Rooter's Tip Of The Day: Most toothed blades, like a hacksaw blade, will leave jagged edges so it’s best to cut poly pipe with a ratcheting scissors.

Use ratcheting scissors when cutting polyethylene pipe to get a clean, un-jagged cut.

If only the band is stainless, it’s an automobile hose clamp, not a marine clamp, and it will rust when buried in the ground.

“Most toothed blades, like a hacksaw blade, will leave jagged edges so it’s best to cut poly pipe with a ratcheting scissors,” says Bob Beall, president of Mr Rooter Plumbing in Northeast Ohio and Southwest Pennsylvania. Normally, according to Mr Rooter, “polyethylene pipe is fastened to fittings with stainless-steel clamps.” Both the band and screw must be stainless, not just the band. “If only the band is stainless, it’s an automobile hose clamp, not a marine clamp, and it will rust when buried in the ground,” says Beall.

Look for “all stainless” stamped on the band. If the clamps come in a blister pack, read the instructions on the back to see if the screw is stainless.

Mr Rooter’s Tip Of The Day

Tip #1 Soften the end of the pipe so it will slip easily on the fitting. Use either a hair dryer or the heat from a torch (not the flame).

Tip #2 When the pipe end is very warm, push the fitting onto it. Use a rubber mallet to seat the fitting until all the barbs are inside the pipe.

Tip #3 Slip two marine clamps over the barbs, rotating the clamp heads to opposite sides to distribute the clamp pressure evenly on the barbs. Tighten the screw with screwdriver or 5/16-inch hex-head driver.example of stainless steel clamps

IMPORTANT TO REMEMBER: If the screw is anodized, do not use the fitting in underground plumbing. Non-stainless clamps will carry only the manufacturer’s name (bottom clamp).
