It is not always necessary to backwash after vacuuming a pool, but it is recommended in certain situations. If you've vacuumed up a significant amount of debris or dirt that has clogged the filter, backwashing can help restore proper water flow and filter efficiency. However, if the vacuuming was light and did not introduce much debris, you might not need to backwash immediately. Always check the pressure gauge on your filter; if it indicates a rise in pressure, backwashing is likely needed.
No, not if the filter is set to backwash or waste.
No, of course not there is always going to be somebody who doesn't and somebody who does.
No, backwashing is used during the cleaning of the sand, when the pressure has gone up on the filter, or you feel the vacuum is not doing its job that is when you should backwash.

When adding stabilizer to a pool you should not have a backwash valve open. Stabilizer should be added directly into the skimmer basket and you should open the skimmer all the way and close off the main drains for 24 hours.
Backwash first then shock. If you shock and then backwash you will be throwing away the shock you just put.
this usually means that the multiport valve in the filter head is bad.. the gauge is not always accurate. replace gauge. the impeller in the pump can also be cloged not allowing you to get any pressure in your gauge. the backwash will be very slow if not any..
