Knife Valves

A knife valve is comprised of a blade that slides between two flexible seals allowing the water flow to be shut off for any repairs need to the equipment with out draining the spa. The flexible seals can be damaged by acidic water when high levels of sanitation are present.

A ball valve, also called a quarter turn valve, is a valve that opens by turning a handle 

attached to a ball inside the valve. The ball has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked.

Spring Check Valve/Swing Check Valve To replace a check valve you will typically need to add in a piece of piping to allow for the piece cut out. If you do not have the slack in the piping to make the glue joint bottom out a leak may occur.

When gluing the valve into place try to hold the valve in a way that any access glue will not run into the valve seat. Damage to the valve seals will occur and a new valve will be needed.

The hose bib or drain valve is installed and connected to the bottom drain in the hot tub to allow customers to drain their spas using a typical garden hose. You will find it inside the equipment area.

To replace a hose bib you will need to use Teflon tape on the threads or a leak may occur.

Do not over tighten or you may crack the female threaded fitting.
