Hi Guys,

 

I have two Astra 99 (750 mm) pool filters, and both of them are leaking around the

seam on the top (picture attached).

 

Is there an easy way to replace those top covers?  Or re-seals them?

 

Many Thanks,

rudi

You probably just need a new lid gasket.

another little trick is to remove the old gasket reverse it then apply silicon grease.

What reading does the pressure gauge read when it is running?

 

It's not the actual lid, it's underneath, between the plastic part where the

lid screws in and the metal part of the filter body.

 

I did open the lib and made sure the gasket was good and applied some

grease on it.

OK if you look at the exploded drawing you will note items 5  and 6.  6 is the o ring that is probably causing the problem this can be caused at manufacture due to in correct tightening sequence.

 

You will have to remove the lid  and drain some water out, and remove the diffuser cone these are pushed over the pipe and usually held in place with a self tapping screw.

Next slightly loosen the union and turn the vertical pipe through 90 deg to allow access to the retains nuts under the rim gently tighten these  one at a time  opposite each other until all have been tightened.

Re assemble and test.

 

If this fails you may have to replace o ring 6.

 

The lid seals on these filters  do not usually give much problems.

good luck.

Thanks for pointing that out. I need to take a closer look and take it all apart !
