my filter is a sand filter and its pressure is reading low just under normal.
Ive only got one skimmer so i really hope its not blocked.

I've tried priming the pump system on my own.
When I twisted off the pump cap (after turning the pump off), there was ALOT of bubbles that rose out of the suction hole in the skimmer box. I waited for it to settle before shoving a running hose into the suction hole.

Doing that got water gushing out of the pump. I cleaned the pump basket and lubed it along with the oring like what you said. then i replaced the pump cap whilst at the same time got a friend to turn the hose off.
I sort of had the idea of trying to trap as much water in the pump as i could.

And it partially worked. I just couldnt get out the pocket of air that was trapped under the cap as i closed it. I switched the pump back on and it filled with water before dropping down to 3/4.

I ran a hose over the fittings before the pump and its still pretty much the same at 3/4 filled.

the suction has improved but the pump is still not entirely full. its enough to get my barracuda going smoothly though.

is it still a big issue that its only 1/4 empty?

No. It may be air coming in that you cannot fix easily or cheaply (somewhere in the ground) or it may be that the pump does not get enough flow having only one skimmer and a main drain to "feed" it.

so the easy answer is no. dont worry about it. as long as the pump doesnt loose prime and the G2 works rock on.

but your filter pressure is still reading under normal? is this normal for you or normal according to the last pool owner? have you backwashed the filter?

So, I checked my pump this morning and its dropped back to its half filled state again :( but the suctions enough to still get the barracuda going.

Umm.. the gauge on my filter doesn't show numerically. Its only got a dial that points to low normal or high. So its reading just below normal.

No, I've never backwashed it, although I have thought about it. Do you mind writing a clear set of instructions on how to backwash my particular system.
I'll give you the specs.

- inground pool
- one skimmer box
- 2 return lines and a main drain

- 1 skimmer valve
- enduro pump (below water level I think because the water in the pump rises when i remove its lid)
- multiport valve sand filter connected to cholrinator and to the returns.

the multi port valve has filter, backwash, close, rinse, circulate, waste.

I'll still continue to try prime the pump until I can get it 100%

REALLY appreciate your feedback alan

First, identify your backwash line coming out of the multiport valve. Labeling everything with a marker will help you memorize it for the future. Your looking for the backwash line because you want to extend the hose or open any valves that may be on it. It may not have anything attached to it at all and just blow straight into the yard from where it sits but often there is a flexible blue hose or hard plumbed pvc pipe that leads out to the grass.

NOTE: Never move the filter valve with the pump on.

Backwashing a Sand Filter:

Step 1: Turn pump off. Extend backwash hose. Open any valves on backwash line.

Step 2: With pump off, turn filter valve to “backwash” setting.
Turn pump on. Run filter at least 1 minute until the water runs clear.

Step 3: Turn pump off. Turn filter valve to “rinse” setting.
Turn pump on. Run filter approx 1 minute until water runs clear.

Repeat steps 2 and 3. If filter is very dirty it may require 3 or more backwashings.

Step 4: Turn pump off. Turn filter valve to “filter” position. Turn pump on.

thanks for the instructions

I've just backwashed the system and my pump is going 100% with full water.

It seems that I cannot leave my pool without a day unmaintained, because another algal bloom looks very prominent. the old algea which I thought I had killed with a pretty large dose of cl has once again turned into a healthy green colour all because of a complacent day I had yesterday.

I think the pool cover I have is playing a large role in promoting the algal growth, because Ive read that a rise in water temperature with low water flow (as i only have one skimmer feeding the pump) can lead to these blooms.

But then, I bought the pool cover to catch the oily gum leaves that constantly fall into my pool. Its a constant battle with algae

O my pump is reading at around 10kpa - so i think with calculation its on 1.45psi.

So what do you think?

I seem to be having a similar problem....

I have a zodiac pacer with very little suction. I have checked all hoses for leaks (even took the hoses out that I thought were a problem but that didn't help), backwashed twice, pulled apart the head and checked the diaphragm for cracks/holes, and I am now running out of options. The pressure guage is in the normal range without the pacer in, but once I attach it to the skimmer the guage drops to zero, although water is still pumping through the filter lid at normal pace. There aren't any air bubbles in the filter lid.

Apart from taking the whole thing to the pool shop, I thought I'd ask here if anyone had any ideas....I've read back through this topic and the only thing I haven't done is lubed the o'ring (considering there isn't any hardware shops open on a Sunday in my area it might have to wait until tomorrow).

Thanks in advance...

Try use petroleum jelly. I used ordinary vaseline to lube the o ring and it worked. make sure you clean the lid and ring off any algae though. and dont tighten the lid too tight.

From what I read maybe its just the gauge that isnt working right. Your system sounds quite normal.

If its your zodiac that isnt moving due to low suction try insert the diaphragm in a different position. Rotate it so its in an irregular position one where it doesnt sit correctly. That often works with my g2.

HELP!- where is this impeller thing on the pool filter.. i have all new parts on my filter, pump, cleaners, laterals, etc. but my cleaners, whether manually or suction seem to work for about 2-3 minutes strong, then bogg down and stop. i can then backwash, or recirc, and they are strong as need be.. its only filter that causes a prob. - the "spider" thing at the top of my tank has been replaced with new parts also...
