any ideas why my deltec ts1250 skimmer has become noisey?

i noticed it when i got home tonight.

i have pulled it to bits tonight to give it a clean out just incase somthing got sucked into where it shouldent, but it was perfect, i had a good look at the needle wheel while i was there and all seems to be as it should. reassembled and tested, skimming ok but still noisey.

its never been totally silent but now its making more noise than my overflow.

there must be a reason why? :-?

i thort of putting a peice of sonthing between the pump and the base of the skimmer to see if that is where the noise is comming from, what would be good for this? i need it to be around 5mm max.

what sort of noise is it.

a hmmmm or more nose from the pump?

The Aquabee flap may have jammed.

You will see the flap adjacent to the impellor with the cover off.

loosen it up as much as possible.

May be that hopefully.

is there a calcium build up

try running some hot water down the air inlet to clear it out, mine gets salt creep from time to time and makes a hell of a racket.

trade it in

I used to let the air in take suck boiling water when ever my 1250 played up and it alway fixed it. But noise was not one of those problems.

it sounds like a pump noise, and it is not skimming properly anymore, the is no real calcium build up, ill try the hot water trick now and let you guys know.

You could also try running it in a vinegar solution. My Deltec MCE600 ran great for a week or two after that. Now it's back to barely skimming.

ok, i ran a cup of very hot fresh water through the air intake, interesting thing the noise stopped while the skimmer was sucking water as apposed to air, this seems to have helped it skim correctly but the noise is still present. deffenatly related to the air entering the pump, any thorts?

cheers skippy, great link.

Ok, by pure coincidence, one of my 1250's did the same thing just this afternoon!

Took it apart completely. I cleaned the impellor and shaft and rubber end bushes a couple of tinmes and it managed to shut up. Took a few times to do it though. The shaft needs to be pushed FIRMLY into place.
