    Bulkhead holes to block

    I would like to know if I could block a 1,5 inch hole in sump with a 3'' piece of glass and silicone. I would put the piece of glass inside the sump and glue it with plenty of silicone. For maximum safty I would put one outside of the sump too.

    Thanx for the comments



    P.S. I would like to this because I have changed my mind and I would like to put my return pump and skimmer pump under water instead of outside the sump.

    Sure I don't see why not. So long as you use alot of silicone. I don't even think you would need a piece of glass on the outside. But thats up to you.

    that depends, are we talking glass sump or acrylic? if acrylic, nope, you'd have to use acrylic,if glass,use glass. best bet, just cap the bulkhead for $1.
    also, are you sure you want submerged pumps?? they tend to add more heat IMO.
