    High pressure in sand filter

    Alright. I understand about the pump and I will clear it when the high pressure problem will be solved. And about the blockage I cannot find any area where it can be. As I told, when I disconnect the return line and install a temporary pipe the pressure is still high (as in the rinse position)...

    High pressure in sand filter

    Yes it's right. I always referre to the filter gauge. Only when we talk about the recirculate ou closed mode, means when the filter is out of order I referre to the MPV gauge, to check what happens. To be clear, a few months earlier, when I hadn't any pressure problem, I remember when the pump...

    High pressure in sand filter

    Update A very busy week carrying out the operations recommended by JamesW and replacing some spare parts. 1st step: THE PUMP: The brand’s engineer told me that the current 3HP pump is barely sufficient for the volume of water to be treated, the entire pool having to be renewed once...

    High pressure in sand filter

    thanks so lot Just 1 more information : I hope that downgrading the impeler doesn't matter with this kind of pool (endless feature) which need water to overflow in a tank behind the pool. And 1 last question : I understand everything about the "sizing" of all the equipments and I will do it...

    High pressure in sand filter

    With all the information you give me, it seems obvious that I should have been more attentive to the technical characteristics of the equipment they offered me during construction. I've just learn a few days ago only that the pressure is offset by the pressure pushing into the suction line. So...

    High pressure in sand filter

    Yes I didn't see it before, but I think at the begining the maintenance team does something ther (maybe replace the o'ring), and now it looks damaged. Easy to buy the spare part, not to install (I checked before trying to tight them, but the nuts are almost impossible to reach from above. No...

    High pressure in sand filter

    Sorry this was a mistake. The equipment is 7 meters below the pool and not "from". Pump : I don't know why the company installed a 3HP pump. When they installed all the equipment, honestly I didn't check anything, they told me "you need this" so I bought it without checking because I had to...

    High pressure in sand filter

    yes those 2 gray valves are always in that position. Not exactly partially closed because in that position it means, 70% of the water flow goes through the SWG and 30% without. No water is stopped. I checked before to by pass 100% the SWG, the filter pressure decreases just a little bit. And if...

    High pressure in sand filter

    Yes, you're right. Waiting delivery of the air purge in the next day, I checked again and the pipe is there, seems to be screwed in the bottom, even if the top of the pipe isn't not there. So unfortunatly, the reason is elsewhere. Yes, I've the same day you ask me to do. The main office...

    High pressure in sand filter

    Hi, Attached photo of the top filter. Cannot see air purge. As I said replying to Texas splash, the problem could be caused by the lack of air purge. I've ordered and let you know. Thanks.
