No suction when using vacuum hose

Postby ctocsrn » Thu 27 Sep, 2007 02:40

I can't get any suction after hooking up my vacuum hose. Everything works fine during normal operation, but when I hook up my hose I don't get any suction. It seems the suction works until the hose filles up with water, then nothing. My jets are working fine. The hose is only a couple of months old with no breaks/cracks. I have tried it on filter and waste.

Are you priming vac. hose before hooking it up to skimmer?
You have to prime vac. hose by sucking on the end of it with your mouth until hose is filled with water, then attach vac. hose to skimmer.
If you do not, you will unprime pump and add air to pump which then needs to reprime. Some older metal pumps will need water added to pump basket as they do not self prime. Newer style pumps which you normally can see in through top of pump lid will self prime and fill back up.
Do you have diverter valve in skimmer? Most one hole skimmers use this to not share suction with bottom skimmer/main drain, just make sure it is turned for suction. If two hole skimmer, you should not have diverter valve.

Also, is th valve to which the hose is attached open (skimmer, vaccuuming port)? Are the other valves closed?

Ps: Another way of priming the hose is by attaching it to one jet till it is full of water.

Can any one help, our pump has no suction through the creapy and very little, or no flow through the side jets, it has been working but since I cleaned the pool it just stopped working, I have backwashed and rinsed, still no suction at all. The inspection glass on the side of the selector is full and clear... is there a block, what can i do

what does pressure gauge read/show?
If it shows no pressure at all then possible clog.

unplug kreepy krauly hose from skimmer, does pressure get better?
make sure pump basket & skimmer have no debris.
impeller for pump could be clogged, take pump basket lid off & basket out. Then take your finger or small screw driver and go down to bottom hole and feel for impeller which should turn easy.

If it still shows very high pressure on gauge, then depending on if sand or DE filter you need to inspect or clean inside.

theres a couple more things you can do but try these first

Got the same problem, pressure is working, everything runs fine, Hose is filled with water, gauge working correctly, just replaced all gaskets... still loses suction. What the hell?

Same problem...very little suction at the hose connection in the pool. Could be a possible blockage in the vacuum line itself since it was working fine for at least 10 minutes then lost the suction. Roto Rooter the line maybe?
