Help with Above ground cartridge filter IN/OUT

Hi,

My son has an old Dryclad above ground pool maybe 10m rectangle and it came with the house he bought. It has worked for him for a few years now without any trouble but lately every now and then (months apart) it pushes out a release plug at the bottom of the filter casing and the pool water goes out until it stops at the skimmer box level.

He says when this happens he cleans the filter cartridge , fills it up again and it is fine for another few months. I figured the cartridge must have been really blocked but he says no more that normal when he cleans it every few days.

On looking at the filter setup I am confused and could do with some clarity if possible.

It is a Pantera PCF60 filter with a lid and pressure meter on the top. It has a paper filter.

On the bottom it has 2 IN's and 2 OUTs.

He has a Onga LTP550 75 HP pump.

An expandable hose goes from the skimmer to the pump inlet and out again to an filter IN.

A filter OUT goes back to the pool through the normal hole

The other Filter OUT also goes to a hose which goes back to the pool but not to any pool connection, just a loose hose.

The last is the second OUT which has a plug in it.

This is the plug that evidently is pushed out due to pressure I assume.

Because the expandable hoses are smaller than the filter IN and OUTLETS, the filter has plugs that are downsized so the hose fits on them.

I can't seem to find anywhere to see whether this set up okay or whether the other In should be the one used not the present one.

A bit confusing for all of us I'm afraid.

Any advise please.

Thanks

John

Hi John

Cartridge filters generally have 2 inlets and 2 outlets so that the most convenient ones can be used when piping the system. Only one inlet and one outlet are normally used, the other two unused ports are closed with blanks the manufacturer typically provides.

The user manual for this filter also states:
Blank off unused inlet and outlet connections using blanks provided

Here is the manual for your reference.

You should consider capping the unused inlet and outlet.

Many thanks Larry for your time and help.

There was a blank in an 'out' however every now and then (not often) this is blown out and the water escapes.

I figure this pressure has to do with the cartridge but the cartridge is still mainly white and when we hose it, little comes out, so I figure it is clean.

Maybe it is not clean but only looks that way.

What do you think ?

John

BTW As far vs I can see his pump LTP 550 (75) pump is okay with this size filter.

Hi John

The blank needs to be lightly sandpapered and glued in with PVC cement to prevent it popping out.
Otherwise you risk flooding the pump area, draining the pool, or some other unwanted situation.

You can keep an eye on the pressure by watching the pressure guage on the lid. An uncemented blank is liable to pop out periodically even without a constant high pressure.

Ah haaa. Thanks Larry..

I decided to clean the filter cart with a detergent we use and brush in case there was oil in it we couldn't see and then put it back in the filter.

I turned it on and it blew the blank out alright !

Thought I'd see if it did it without the cart in, so removed it and turned it on and after a few seconds of strong flow, it popped again.

The gauge has blue to about 120 then red for clean and I see even after a clean, the gauge shows near the 100.

Is that too hot!

Anyway as you suggest, I will cement it, like I did with 'in' and 'outs'.

Strange thing is I wonder why this has just started to happen.

Appreciate you help..John

John

As long as the pressure doesn't go into the red you are fine.

The blanks fit snugly but over time and each time they pop out, they begin to get looser. So the longer you use them like now, the quicker they will free themselves as time goes on.
