My Pool: Is an onground pool with a 6' deep end. The bottom drain was closed off when I had kids with long hair. I add everything into the skimmer. My husband always looked after the pool and I swam in it. I lost my husband four years ago to a massive stroke and this pool is a real mystery to me.

My pool pump was working fine until I vacuumed it the last time. Now, it won't hold the prime. I undo the lid on the basket and it fills with water. I replace the lid, turn on the pump, the pressure gauge goes to about 14 and then drops right down and stalls. I am a real beginner to all of this. My son usually looks after it, but I am attempting to regain my independence. The pump is a TS Series (TS 100). The water in the pool won't fill past the skimmer.

It seems that you are sucking in air
Lubricate the "O" ring on the pump basket lid with Vaseline or Silicon grease, this will enable you to tighten the top more securely (you may need to replace the "O" ring)
Check for cracks in the lid or adjacent pipework
Check the skimmer flap isn't stuck upright
Check the water level at the skimmer, do you mean that you can't add any more water to the pool to raise it past the skimmer
