Why does my spa drain into the pool?
Most commonly, it is simply due to a failed, or stuck check valve in the plumbing at your equipment. A raised body of water that actually shares the same system as the main pool that is lower than the spa naturally wants to drain into the main body of water below it because of gravity.
Why did water drain from hot tub?
If anything gets trapped within that valve, such as debris, it can disturb the flap and prevent the valve from sealing properly. That allows the water to flow backward and drain instead of remaining inside your hot tub.
Why is my spa draining when pump is running?
There is normally a check valve in the plumbing at the equipment pad to stop water from draining from the spa to the pool. There could be debris in the check valve or it could be failing due to age. A pic of the equipment pad might help.
Why is spa draining in spa mode?
The suction valves need to be adjusted properly. Turn the spa suction valve to the “off” position and make sure you have the spa return valve at least partially open. This will help the flow between the pool and spa. You may also want to see if the actuator has gone bad if the suction valves are fine.
How does a spillover spa work?
Spillover spas are hot tubs that connect directly to your pool through a small curtain or fountain of water. This water moves directly from the jacuzzi into the swimming pool, spilling over a ledge or a series of ledges.
Is it normal for a hot tub to lose water?

Why does my pool lose water when the pump is on?
Pressure-side Return Leaks. Generally, if you're losing water when your pump is running, you have a pressure-side return leak. When you're running your pump, the plumbing after the pump is under pressure. Often times, this can lead to small leaks and water sprays through your line (from the filter to your return jets.)
Why is my hot tub going down?
It may simply be that your tub's inflation valve or deflation valve adapter is faulty, or that it's too loose. A loose inflation valve is likely to be a key cause of air escaping through a Lay-Z-Spa. Once again, it can be uncommon for problems like this to arise in the most robust of tubs.

Why is my hot tub leaking from the bottom?

Why does my pool pump not seal?
When the pump shuts off, water cannot flow back through the pool returns, which prevents the spa from equalizing and allow it to remain full. The parts inside of the valve can become worn over time, and in turn, cause it not to seal correctly after the pump and filter system times out.
What happens when the pool level is higher than the spa level?
If the spa's water level is higher than that of the pool, when the pump stops pushing water to the spa and pool, the spa will equalize itself to the level of the pool in a process known as equalization. No water is being lost.

A pool/spa combination pool uses the same water for both the spa and pool. Most use the same pump; some may have an added spa pump. Valve position is the main factor in determining where the water is flowing. The most common position for valves is to direct water to both the pool and spa in order to create a spa "overflow" or fountain effect ...
What is a spa spillover valve?
The most common position for valves is to direct water to both the pool and spa in order to create a spa "overflow" or fountain effect when the spa is not in use. This is referred to as "spa spillover". Many systems are now using automatic valves called "actuators" that are motorized and controlled by the touch of a button via an installed ...

Why does my pool drain water?

What is a check valve in a pool?
The check valve prevents back water flow from going into the pool. Sometimes, that valve goes bad or gets stuck allowing the water from the spa to drain back into the swimming pool. It’s an illusion! There is no actual leak. Essentially, it is just moving.
Why should the spa drains be cracked open?
They should be set so that there is more water going to the spa than the pool to get the waterfall effect into the pool the spas drains should only be cracked open to help keep it clean. These valves may have gotten out of sinc due to a power bump /someone moving them with the switch etc.
Why is my vac pump draining down?

Where does water go in a pool pump?
water enters the front of the pump , is pumped to the filter then to the heater [ and or solar , if you have it ] and to the return jandy valve to the pool, however if you look at the return plumbing you should see a pipe connecting the pool return and the spa return with a check valve , this is the spa by-pass .
Why are my jandy valves out of position?
They should be set so that there is more water going to the spa than the pool to get the waterfall effect into the pool the spas drains should only be cracked open to help keep it clean. These valves may have gotten out of sinc due to a power bump /someone moving them with the switch etc. Its probably just a valve setting if you haven't seen a water lose or you don't see air bubbles from returns when running, which would be a sign of an air leak on the equipment.

Is The Spa Leaking?
If It Doesn't Leak, Why Is It draining?
- If the spa's water level is higher than that of the pool, when the pump stops pushing water to the spa and pool, the spa will equalize itself to the level of the pool in a process known as equalization. No water is being lost. Although it's not very noticeable, the pool actually receives the amount of water that has equalized from the spa.
What Is Causing This, and Can It Be fixed?
- This canbe fixed! The cause is what is known as a check valve. There may be either an existing check valve installed that needs replacing or no check valve at all. This valve uses a spring (or floater ball) inside it to allow the water to flow in only one direction. When the pump shuts off, water cannot flow back through the pool returns, which prevents the spa from equalizing and all…
