    Can I lower my Blower bell?

    The blower for my spa is for some reason, 5 feet off the ground and right in front of my control panel.
    Any reason, I can't just cut that PVC pipe a foot or 2 shorter and lower it?

    Mine is about 6" off the ground.

    If your pool is higher than the thing you'd need it higher to prevent water from draining out.

    Mine is 4-5ft too, but the only reason is because the switch for it is attached to the side of it, and there are bushes down low, so it was convenient. It's just a plain ole pipe below it, and I doubt cutting a few feet from it will cause an issue...if anything maybe slightly stronger bubble action in the spa?

    Ours had to be raised because it's a little down a slope and water was getting into it.

    Stupid pool builder should have known better.

    Pipe should be at least 2 ft higher that the body of water it serves. Example: If your pool equipment is at the same elevation as the pool water level, and you have a 18"-2' raised spa, your blower could need to be about 4' off the ground (at the equipment). When the blower switches off there could be a "surge" of water that travels back up the air line, and this is why the blower needs to have that extra height to it, to keep water out of the blower motor.

    That makes sense---I've read that some of these blowers have check valves that I would think would stop this from occurring, allowing a lower install point...is that always the case?

    That's great until the check valve fails.
