Possibly, if you don't interfere with the motion of internal parts. -Check valves are not expensive, better to replace it if any doubt exists.
If your filter is repaired then you can just vacuum the pool.
You need to have your check valve replaced.
To blow up a kiddie pool, first ensure you have a suitable air pump, which can be manual or electric. Begin by locating the air valve on the pool and removing any caps or plugs. Insert the pump nozzle into the valve and start inflating until the pool reaches the desired firmness, then securely close the valve. Always check for leaks or damage before filling the pool with water.
No
yes they can! i just found pool tracks on INYOPOOLS.com...
To determine if a pool valve is open or closed, check the position of the valve handle. Typically, a valve handle that is aligned with the pipe indicates it is open, while a handle that is perpendicular to the pipe signifies it is closed. Additionally, you can observe the flow of water; if water is flowing through the system, the valve is likely open. In contrast, if there is no flow or pressure, the valve may be closed.
To plug your blow-up pool, locate the air valve, which is typically found at the top or side of the pool. Use the plug that came with the pool, inserting it securely into the valve to prevent air from escaping. If the pool has multiple chambers, ensure all valves are plugged to maintain proper inflation. Finally, check for any leaks by feeling around the seams or using soapy water to identify bubbles.
A Hydrostatic valve is basically a plug that stop water coming down out of the pool, but when the water pressure under the pool gets higher then the pressure in the pool it will let water into the pool from underneath in order to stop the pool from floating in ground water.
First of all if the water table it too high you do not want to drain at all for your pool will act like a boat and float up out of the ground. If you are going to empty and refill rather quickly say 3 days or less. In the main drain of your pool there is a check valve that allows ground water to seep into the pool so when the water table gets to high your pool don't float. The valve is a one way valve that pops up when ground water is refilling your pool.Put a brick or something heavy over the valve to prevent it from opening and pump out your pool.Be sure to refill pool soon.

A hydrostatic relief valve prevents your swimming pool from wanting to become a 'boat'. If the bottom of the pool is below the level of ground-water, and the pool is emptied, the pool would want to float in the underground water. I have actually seen the deep end of a 40ft gunite pool (with no hydrostatic valve) rise out of the ground (by 18") when the pool was emptied for repairs. A hydrosatic valve would have opened (and allowed the underground water to flow into the pool) when the water pressure beneath the pool became greater than the water pressure in the pool. I am not sure if you can manually test the valve, so check with the supplier/pool builder. A hydrostatic relief valve is located in the deepest part of your pool. It may be under the maindrain cover or in its own little box on the bottom of the pool. The purpose of the hydrostatic relief valve is to relieve a build up of pressure if it occurs from underneath the pool. If the water were to be removed with a high water table then the pool may float up out of the graound like a barge. You then have a big problem on your hands. The fhydrostatic relief valve will open allowing the ground water to enter the pool to keep the equalibrium and to relieve built up pressure from underneath the pool. The valve typically does not need any maintenance. However, if the vavle has opened then there is a chance that a tiny particle could get stuck in the seal when the valve closes again. The tiniest particle (which may not even be seen) could allow water to seep out of the pool into the ground. There's a lot of water in the pool and each gallon of water weighs 8.33 pound. A typical residential pool of 20,000 gallons holds water weighing about 166,600 pounds. A commercial pool of approximately 120,000 gallons has water weighing approx. 1 million pounds. Removal of this much weight obviously changes a lot of things. You need to be very careful removing water from a pool. Things to be concerned about are high water table, underground springs, rainy weather, hills behind the pool. Please write if there are any other questions.

FURTHER ANSWER When you find your pool losing water and don't see any obvious place, it may be the hydrostatic valve has lifted and then not seated properly. The valve needs to be flushed by being lifted momentarily. I have done this by donning a mask and with fins and weights swum down, removed the grate, and lifted the valve by hand. If you have never seen such a valve find one in a swimming pool store and see how it works. Also, be sure there is not a lot of trash in the fixture near the valve or again it may not seat. Best to do this with the pump off if the valve is in the drain box or you may get caught by the suction. This can lead to serious death! Paul Delage
The check valve between the spa and the pool is defective.
No, because gunite will not dry if it is constantly being mixed with water. Drain your pool first.
