Q: I’m upgrading my pump. Do I need new tubing as well?

A: Congratulations on the purchase of your new toy! To get the maximum flow out of your pump, you’ll need to make sure your tubing size lines up with your flow rate.

Here’s what we recommend:

  • Up to 500 GPH: ½ inch tubing
  • 501 – 900 GPH: ¾ inch tubing
  • 901 – 1,500 GPH: 1 inch tubing
  • 1,501 – 2,700 GPH: 1¼ inch tubing
  • 2,701 – 3,600 GPH: 1½ inch tubing
  • 3,601 – 5,400 GPH: 2 inch tubing
  • 5,401 – 13,500 GPH: 3 inch tubing

When it comes to selecting a type of tubing, you can choose from three different types: flexible PVC tubing, flexible kink-free tubing and flexible black vinyl tubing. Each has its own unique features and uses. Here’s what you need to know:

Flexible PVC Tubing

Ideal for water features, flexible PVC tubing can have water in it year round without damage from freezing temperatures, and the pipes can be buried. To join the lengths of pipe and plumb your pump, you will need to use schedule 40 PVC fittings and PVC glue. Flexible PVC is the most expensive of the bunch, but it’s your best choice for high-flow pumps. It comes in 1½” to 4″ diameter.

Flexible Kink-Free Tubing

The most popular and widely used water feature tubing, flexible kink-free tubing makes plumbing jobs a breeze as it requires few pipe cuts and unions. The heavy-duty tubing can withstand freezing temperatures and being buried. Connect the tubing with barbed and insert fittings and hose clamps rather than messy glue. We have it in ½” to 1½” diameter.

Flexible Black Vinyl Tubing

Ideal for smaller pumps, fountains and statuary, flexible black vinyl tubing is connected with insert fittings and hose clamps. It’s not sturdy enough to withstand being buried or left out in freezing temperatures. We carry 3/8″ to 1″ diameter tubing.

Get the most out of your new pump with the right tubing in the right size. You’ll be glad you did!
