When pump and filter are off, spa drains into pool: spa water drains down to intake valves at bottom of spa, pool water level rises. Have been told this problem may be due to a faulty check valve; how to locate check valve so I can take it out and bring it in to the pool store to buy a new valve? I don't know what product to choose on the product list.

if you have a sand filter. you can economize and perform a long backwash cycle. this will clean the sand and lower the water level. otherwise, just use the drain/waste option. if you have a cartridge filter, your manufacturer should have installed a three way drain valve between the pump and filter. by turning this valve, the water will be diverted from the filter to waste
if the pump is above water level there is no need for valves. If the pump is below water level, partially drain pool until water level is below pump, then install unions and shut off valves when you remove the pump.
VALVE SETTINGFUNCTIONS OF VALVE POSITIONSFLOW DIRECTION THROUGH VALVEFILTER
PUMP - TOP - THROUGH FILTER - BOTTOM - RETURN
For normal filtration and vacuuming pool through filter.
PUMP - BOTTOM - THROUGH FILTER - TOP - WASTE
For reversing flow for cleaning filter.
PUMP - TOP - THROUGH FILTER - BOTTOM - WASTE
For initial start-up cleaning, plus resetting filter bed after backwashing.
PUMP - WASTE
For vacuuming directly to waste, lowering pool level/draining pool.
NO CIRCULATION PAST PUMP PORT
For shutting off all flow to filter and pool.
PUMP - RETURN
For bypassing filter, but circulating pool water. May be plumbed for "off-system" pool
water access. Ideal for Jet-Air® fittings.

What are you using to drain the pool? A sand pool filter is not the best option for draining. You need a submersible pump for that. Why are you draining the pool? The filter should be used to filter water, not drain. It is possible, but not efficient.
the actuator at the intake of the pump divides spa intake and the pool intakesmake sure switch on actuator is on 1 or 2 if in pool mode the off should be at spa intake the out inpool postition the off should be to the spa outlet
you do need to set the filter valve to waste but you need to make sure the valve on the suction side of the pump is pulling water from the pool instead of the spa. Also, if you have a separate skimmer and main drain valve on the pool suction, make sure the skimmer valve is turned off. Otherwise, you will keep losing suction. If you don't have a separate skimmer and main drain valve, you may not be able to drain the pool with your equipment.
This problem can be caused by a couple things. the two most likely culprtits are either the absence of check valves and or incorrect actuator settings when the pump shuts down.
Your spa is most likely higher than the pool. You most likely have a spill over (waterfall) feature from the spa into the pool. This is so the spa water can be recirculated in pool mode. One of your actuator valves may be slightly off closed position in order to allow spill over in the spa, or you may have a dedicated overfill pipe in the circuit to feed water to spa in pool mode.
Whichever spill over piping you have set up, when the pump shuts down, water from the spa ( higher level than the pool) will backfeed through the overflow spa circuit, back through the pump and into the pool through either drain or return. Effectively rendering your spa level the same level as your pool.
To fix this problem, simply install check valves into the spa runs and as a secondary measure put one into the pool return run ( the run that feeds water to pool).
This will insure that when the pump shuts down, no matter which position the valve actuators may be set, water can not back feed through the pump circuit from spa to pool.
