![]() ![]() Varying the discharge pressure to the siphon will also allow the pump operator to vary the speed in which water is transferred. ![]() Make sure you tie the suction hoses down as they will tend to walk and shift the more pressure you put to them. And don’t worry about pressurizing the hard suction in this application as you won’t be putting enough pressure to cause any damage. In most cases, pressurizing your suction hose is a big no-no. The beauty of this arrangement is the water keeps circulating in the pump to prevent freezing in the winter and to prevent the pump from overheating from re-circulating water just in the pump. Three or more tanks set up work the same way, but you’ll need at least two power jet siphons and two available discharges. If you’re the supply engine, that shouldn’t be a problem because all you’re doing is keeping the large diameter hose (LDH) filled. So, the crosslays, the rear discharge, other disharges on the pump panel should be available. You can even use a gated wye to get more discharges. It might get a little tricky to do if you’re the attack engine and you’ve got a number of hand lines off, but you should be able to find at least one unoccupied discharges. In reality, if you’re the attack engine pump operator, you shouldn’t have to worry about water supply issues anyway – at least not in the perfect world – as mutual aid crews should have automatic responsibilities for that. Having three full portable tanks on the ground, linked with power siphons and tankers backed up to each is a thing of beauty for the pump operator. TFT SYPHONER BUILD PORTABLEĭepending on the size of the portable tanks and the size of tankers/tenders backed up waiting to discharge, you could be able to tell the incident commander that you’ve got 12,000 gallons or more waiting to be sent. ![]() More realistically, the pump operator has been busy getting as much water to the scene while trying to set up the multiple power jet siphon operation. ![]()
