Of course, the one question that hasn't been asked is "Why?" Normally, mechanical equipment is placed on isolators to reduce noise and vibration. Why? Because the equipment runs periodically or often during the day and can be disruptive to the building occupants if noise is not abated. How often is the pump going to run? 5 minutes per week? Seems that could be mitigated by doing the tests outside work ours - or just letting the occupants 'suffer' for 5 min. per week.
Yes, I know - in a fire scenario that pump could run for 1/2 hour, maybe more! Not only is there a fire, but they can't get any work done due to all of the noise from that damn pump! Maybe the cost of the isolation and the flex piping is justified... Mark A.
