Hot Tub Plumbing FAQ's

What size plumbing do I need for my hot tub?

Plumbing for your hot tub can be measured in imperial or metric. Imperial sizes range from 1/2” to 2” but be sure to measure the outside diameter to get the right fitting for you. Use our handy guide to help you find the fittings that you need.

Do I need flex or rigid pipes for my hot tub?

Flex pipes are used to connect to all of your jets so they can bend around your internal components. Rigid pipes are used on the suction manifold because it is under more pressure and a flex pipe could collapse.

What kind of glue do I need to use to create a watertight seal?

We recommend you use a wet or dry cement glue which is specifically designed for plumbing. Have a look at what we have in stock here: Glue product page
