Has it worked OK in the past because that flap in the valve should be held closed with the head of water above it unless the solar panels are lower Sent from my iPhone using Tapatalk

I suspect the valve is to stop the water flowing back from the solar panels, so IMHO it should be on the solar flow Sent from my iPhone using Tapatalk

You could use a spring loaded one if it's not possible to change the position Sent from my iPhone using Tapatalk

It looks like that valve should be on a vertical run not a horizontal run Sent from my iPhone using Tapatalk

Your water table and pool construction will determine how much to drain down 1/2 would get you to 120ppm and then start your slam The high CYA will render your chlorine ineffective Sent from my iPhone using Tapatalk

What is the water level at the skimmer? Is the skimmer flap jammed up? Sent from my iPhone using Tapatalk

I'm quiet happy with the pressure now. I was just enquiring whether there were shorter lengths of flexible pipe with the cuffs

I replaced my pump for a smaller one and now my pressure is down to 9 PSI and filtering OK I used some flexible pipe for connection but they come in 5 feet length. Are their shorter ones Sent from my iPhone using Tapatalk

Bear in mind that is the surface area at the top Sent from my iPhone using Tapatalk

D x D x .7854 divided by 144 equals 2.88 square feet Sent from my iPhone using Tapatalk

No I don't have a two speed pump and I think it's to powerful for my pool (290 litres/minute) My thoughts were the same to put a valve after the pump Running to waste works but uses a lot of water. A 10 minute run uses nearly 3m

My pressure through my sand filter which is now glass media is 18PSI I'm experiencing fine particles on the pool floor I used quiet a bit of DE as previously advised starting of with a cup then adding more but the pressure didn't rise and the fine particles seemed to go straight through the...

Yes that would be ideal Sent from my iPhone using Tapatalk

How about cutting the copper pipe, unscrew the complete section from the pump, remake the plastic joint to the pump and then rejoin the copper pipe You will need to excavate the ground a bit

Have you tried just opening skimmer 2 valve just a bit and slowly increasing untill it works correctly (it's balancing as in any heating system)

If your fill water is 250 CH you won't notice any difference whereas the fill water has no CYA and you will notice a difference

I know of someone who changed their sand filter and replaced it with one With a small bather load indoor pool and were quite happy with it If it isn't widely used I won't bother looking further Sent from my iPhone using Tapatalk

Here is one link

Does anyone have any information on the pro's and con's of a bag filter against a sand filter

I'm glad I asked Thanks

Being as I don't need much I have been looking on Ebay and have come across food grade Diatomaceous Earth is this the same? The flocculant is removed and a deep clean done on the filter. I have also started the OCLT. My indoor pool has a thermal blanket over it so it should be unaffected by the sun

How much DE should be added to the filter, so that I know how much to purchase

I have virtually finished slamming but still have cloudy water which doesn't settle I have vacuumed but there was very little to remove There is a flocculant in the filter from the pump skimmer basket The image is at a depth of 3.5 feet

It's a bit cloudy after doing an AA stain treatment and finishing it of with an underwater acid wash I have only been using sodium hypochlorite 13.5% Sent from my iPhone using Tapatalk

Does anyone have a link to a pool level chemical log sheet

Thanks for that I couldn't find anywhere on the site about indoor pools Sent from my iPhone using Tapatalk

Is there any difference between slamming an indoor pool against an outdoor pool FC 2.6 CC 2.4 PH 7.6 TA 100 CH 480 CA 20 Temp 30 Celsius

That seems ideal, why don't they ship that in the kit My problem is being in the UK it takes ages to receive it, that is if I can find someone to ship it
