vacuum loses suction quickly

Postby Kenny » Wed 13 Jun, 2007 20:40

When I'm vacuuming my above ground pool, I start with real good suction power. Within 2 or 3 minutes, I have lost all suction. I backwash the filter, but the backwashed water isn't very dirty. I start vacuuming again and have real good suction for another 2 or 3 minutes, but again, I lose sucking power. I backwash again, and again I have good sucking power for a couple of minutes. I have not had this problem in past years.
Do I have a problem with my pump or filter?
Thanks,
Kenny

Sounds like your pump is losing it's prime. When this happens, does it suck all the water out of your pumps basket?

I have that same problem on my in-ground pool. The pump basket does drain almost half way. Afterwards in order to get it to filter properly again i need to place the hose back in the filter basket and re-prime. any and all help is appreciated. I am past my last nerve!!!

Could your vacuum hose or skimmer connection be allowing air to get in the system?
Does suction come back once you just turn the pump off for a few minutes, without backwashing?
Does suction come back if you throttle into service another suction source?

Losing vacuum suction

Postby StarterPool » Sat 07 Jul, 2007 06:31

I am so glad that I found this website! I have been searching the Internet to try and find the answer to this very question!

I am having the same problem as everyone else that has posted. My above ground 24' pool is only one year old and this year I have not been able to keep the pool clean because my vacuum keeps losing its suction and it is becoming a hassle to vacuum.

Here is my problem:

I backwash and rinse the pool and then set it to filter and all is working well -- nice water pressure. I set up the vacuum, fill hose with water, wait for all bubbles to settle, and insert the hose - the vacuum begins working fine -- excellent actually. Then, after about 30 minutes, it just stops.

I check the vacuum - making sure not to get air in the hose - no blockage. So I undo the vacuum hose and notice that there isn't any water coming out into the pool (sorry, I don't know all the terminology).

So, I turn off the pump, set the pump to rinse, rinse for a few minutes, and reset it to filter and BINGO! I have water coming back into the pool with nice pressure. I set the vacuum up all over again and it works -- but only for about 30 minutes or so.

This is very frustrating. I thought I might need to change the sand, but I've only had the pool for one year.

What else can I do? Thank you so much!

It's not your sand. If you backwash does it last any longer?

It sounds like you have an air leak somewhere. Double check all your fittings to be sure the pump isn't sucking air when under strain (vaccuming).

Vacuum suction

Postby StarterPoolUser » Sat 07 Jul, 2007 14:18

Thanks, Backglass. I don't notice a difference when I backwash or rinse. I'm basically just doing that (backwash/rinse) to throw off the pump and get it started again (similar to rebooting a computer!). It seems to work, so that's what I do each time.

I've taken apart the entire vacuum and found no leaks/issues with it ( I have a DirtDevil pool vacuum for above ground pools).

I haven't thgought of checking the fittings around the pump -- honestly, I'm afraid to mess with any of those connections since I'm not sure what to do if I mess things up.

When the installers came to install the pool last summer, all they left me with was one sheet of paper with very vague drawings and instructions. I thought I would have gotten a "users manual" or something! lol

Do you, by any chance, know if something like that exists for real novice pool owners like myself?

I appreciate the help and any feedback you can continue to provide. Enjoy your weekend!
