Double Clamp

[Zebra]

Well maybe ive been fortunate but the last time out i noticed just a little water maybe coming from my clamps. My setup is floor drain to a T and splash well to the outside. Everything is just single clamped. I know the rule is below waterline dbl. clamp is that what everyone has. Pain in the *** to reach down there to work on things. Only way thru top hatches on corners. I guess bigger pain in the *** if one comes lose. Just wondering if there is a better mouse trap someone is using.
