newbie with pool... pressure problem.

[Bleach=Chlorine?]

just bought a house. First pool.
Sometimes when I vacuum... especially if the vacuum meets some resistance like when it sucks real well at the bottom of the pool, it will stop working. No more sucking action... no more jet in the pool. Then I unplug the vacuum from the skimmer (I have one skimmer and one jet in the inground pool) and after a minute or so, everything starts again.

Now, that wasn't to bad but I bought a barracuda. When I plug it in the skimmer, it will work for max 15 seconds before it stops sucking and before the jet stops.

Also, when I vacuum, a lot of bubbles come out the jet.

You are probably losing prime on the pump because it can not draw enough water. To figure anything out we would need additional info (Motor HP, Age of Equip, distance to pool, uphill/downhill, valve settings - 100% skimmer or 50/50% skimmer/drain). Thanks

I tried to get as much info as I can. 1 Hp motor. Must be 25yo. 15 feet from pool. Ground level... very level not uphill.

The filter is a jacuzzi 20fm spec B
THe pump is a jacuzzi IL-s/B
Mod: 1103022423
rpm: 3450
Date code: L83

Also, the drain in the bottom of the pool is not working. The last home owner told me that. And I have only one jet working, the one nearest to the drain at the bottom of pool isn't. Are they connected those two?

So hope the extra info can help someone help me. Thanks a lot

If your drain isn't working, when flow to the skimmer stops while vacuuming you will lose prime.

So what you are saying is my problem comes from the drain not working?
If my drain at the bottom of pool is not working... what might be broken???

Could have a leak in the line and they plugged it. Could be the type that routes through the skimmer and they didn't take out the plug in the skimmer when opening the pool. Could have a bad valve. Could be clogged. Could be that the pool loses prime if you open the valve to the drain suddenly (which is not uncommon) making them believe it didn't work.
