Inground Pump For Above Ground Pool?
by Mark
I need to get this fixed ASAP because I am going on vacation for 2 weeks and it won't be pretty when I get home with no pump. My question is I found a Max-Flow Hayward INGROUND pump (C48L2N134B1) fairly new (3 months) locally . Will it work? Thanks for the question Mark There are normally two factors between an above ground from an inground pump. 1. NPSH (net positive suction head). This is much lower on an above ground pump. Normally they don't prime a pump that is above the pool's water level like many inground pumps. 2. Above ground pumps tend to be lower head. They are usually close to the pool. Since this is so, they don't have as much head loss as an inground pool where the pump is situated farther away. The result is above ground pumps don't need to be as powerful as inground pumps and is usually a little less expensive. You can use an inground pump for an above ground pool, but it could damage your filter. Hayward Superpumps say in their owner's manual that "these should only be used with a permanent pool". In other words, an inground pool. You need to consider the "low head" of the pump. Using a high head pump (inground) on a low head loss pool (above ground) will result in the pump not having enough load on the impeller. This is not only inefficient for energy usage but it can also burn up the pump. Above ground pumps are usually plumbed slightly different than inground pumps. A good page to look at is this: http://www.poolplaza.com/inground-aboveground.shtml The short answer is that although it might work, consider the horse power of the inground pool pump and be sure it's 1/2 HP, 3/4 at the most. Anything more might damage your system because of the force of the inground pump. As was stated, pool pump are made specifically for above ground and inground pools.
