If your tub is porcelain over cast iron and the cast is not cracked your ok. If the cast is cracked then the chances of the crack continuing are great, more so with any vibrations and changes in weight distribution.

    Arthur, thanks for pointing out that there are high chances of a crack in the cast getting worse. It makes sense that vibrations and changes in the weight distribution could cause it to crack even more. My husband and I recently noticed a crack in our bathtub. It seems to be deeper than just the over cast, so I assume it is important to contact a repair service right away so there is no more damage done.

I am trying to loosen the plastic nut under the toilet tank. The tank seems to be leaking from this spot.

i use a spud wrench, cheap one is about 6$ but, check your rubber flat washers on your tank bolts,they get hard and crack, or it's possible that your tank has a hairline crack running from tankbolt hole to tankbolt hole, both are common problems

Is it possible to drill into a Kohler cast iron shower pan, without cracking the porcelain? I need to secure a track for a shower door. -- Thanks!

Yes you can but you've got to buy a special bit. Porcelain will dull a brand new bit in seconds. You've got to get a carbide tipped or concrete drillin bit. Also while you are making preperations to drill put a piece of wide masking tape over the spots to be drilled. Don,t push down too hard and let the drill do the work. Good luck.

We have Builders #6032 and it has small hairline cracks in tub bottom. Its starting to leak into our basement. What do we do to fix it?

alot of times if you call the tub builder they have service guys who will come and fix your tub. most tubs have a 3-8 year warrenty against defects so you could get the fix for free. if not you can always try and get fiberglass resin and mix a batch up and seal the cracks yourself

My porcelain covered bathtub has tons of ''spider cracks'' all over

crack in porcelain is going to affect the cased iron shell. if you don't fix them. water will seep through and cause the iron to rust.
the cause of the cracks are from the extreme temperture change in the room or the floor.
there are no easy fix for this. you can get a tub insert from any of the home center. I can tell you what the price is, since I haven't done any home remodeling for 3 years. price change.

Four inch crack in the bottom of aquaglass tub styren

I would contact Whirlpool directly to even see if it is possible. I tried to repair an acrylic tub one time and it didn't keep because the the constant water on it. If it can be repaired, they will give you the solution and info for a contractor that might be able to do the work if you can't do it yourself.
