If you have a dedicated suction for the vacuum hose (illegal in Australia) then you close the skimmer to increase suction.
Use a suction vacuum plugged into your skimmer to vacuum to waste.
Doesn't really sound like a question. But your swimming pool suction is determined by the size of your pump. There are other factors like the pipe distance and diameter, but it basically comes down to the size of your pump.
A pool vacuum leak could mean that there is a leak in the vacuum hose that you use to vac the pool. Or it could mean that there is a leak on the suction side of the pump. It could be located somewhere between the skimmer and the inlet of the pump. At the pump it could mean that there is a leak at the pump seal or the pump lid or a pump gasket. Some of these leaks will not produce water at those leaks they may only suck air into the system. k
you may have to prime your pump Clean or replace the filter.
There are a few solutions. Do you have multiple skimmers - 2, 3, 4 the plug all the ones that you do not have the vac hose plugged into. There may also be valves that you need to close or open to get you suction for vaccing the pool. You may also have to evacuate the vac hose of all air.
In regards to comfort and safety while swimming, yes a hose can be too long. Also, the hose might also be able to tangle and/or not allow the cleaner to move correctly and to its full reach. Lastly, The suction power needed for a longer hose would be greater; to measure suction the vacuum might have come with a neat gadget that reads this and tells you the optimal level of suction. Hope this helps! :)
No, you do not have to. You just have to be careful not to swim into them.
To keep your swimming pool clean you will need a filters and a water pump. A vacuum would as be a good idea.
Because the pump is set to "vacuum to waste".
Low suction from your pump, damaged hose,
No they couldn't.One thing is that if water is in there it will get stuck. But this could work if there's no water in there
