Question concerning initially filling the pool by hose or can I get a water truck with ph balanced water? Builder is insisting I fill by hose and I do not understand why. Pool finish will be pebbletec. Builder claims using a truck will damage finish due to pressure of hose and pipes in the pool and he has to acid wash which makes no sense. I disagree and would Never allow high pressure on new aggregate and at very least difuse it at the beginning until a certain level. I think it’s because he does not have the time to come and do initial start up for the week and just an excuse. Is he correct or can I just fill and get process started.
