The RainFlo MHP75A is an automatic 115V/60Hz 4-stage 3/4 HP centrifugal surface pump with all stainless steel 304 construction in the water end of the pump. The RainFlo MHP75A automatically activates when water begins to flow from user demand such as an irrigation valve opening or a hose end sprayer being operated. When water flow stops, the pump shuts off. The pump control unit also features run-dry protection with a built-in pressure gauge. These pumps are great for whole home rainwater harvesting systems, irrigation systems or well water storage systems. Poly-Mart distributes a line of water pumps and submersible water pumps by RainFlo.

Ships FREE with the purchase of any Poly-Mart Tank!!

Poly-Mart Shipping Details:

On arrival, inspect the shipment immediately for obvious signs of damage. If any item is damaged to the point that you do not want the product, do NOT sign for the shipment and do NOT take possession of the product. The freight carrier will then be responsible for returning the product back to the factory, and we will arrange a rush replacement product to be sent back out. When you sign for a shipment you are signing that it is in good condition and you accept the shipment. This will relieve the freight carrier of any claims!

Should you determine that any items are missing, you MUST note the missing items on the delivery ticket and contact Customer Service to report any issues. You should open cartons and containers. If there is the slightest doubt that the merchandise is damaged (concealed or not) refuse the shipment and do not sign for delivery.
