Leak at connection to Sand Filter

[PoolCleanerMom]

this afternoon we noticed that the concrete around our sand filter was wet and it looks like the leak originates at one of the connections to the pump:


Any tips on further DIY diagnosis? Is it feasible to attempt a DIY fix when, as hubby says, "I don't have a wrench nearly the right size"?

For reference - this is a bigger-picture view of our system. Hubby emptied the pump basket and re-primed the system so not all the water on the concrete is a result of the leak - original leak zone extended roughly 4-8 inches beyond the base of the filter


Thanks!

go to lowes by a big pair of channel locks. Try to tighten the union. Their is also O-rings on the inside of the union you could try greasing.

I agree with jodeci77. I bought these and have used them countless times on pool fittings. http://www.amazon.com/Channellock-480-2-Inch-Capacity-20-Inch/dp/B00004SBCX

They are HUGE, like cartoon huge, and they fit those fittings. If you can't afford that, you can get a strap wrench for about $10, but they are rubber and tend to break easily.

Take the union off, and try greasing the o-ring and putting it back together. If that doesn't work, take the o-ring to a plumbing supply store and get a new one for about $1.
