Question: I have a pull up stopper that does not seal and I cannot remove. I need a stopper that goes over the existing stopper.
Document: The stopper keeps a nice seal around my tub drain. Water does not seep through. Easy to apply and remove. Just what I was looking for.
This stopper works great. One of my tubs has a very slow leak which is not a problem since it is only used occasionally. However when the snow storms hit and I fill this tub for a source of water in case the electricity goes out it slowly leaks out. I used this stopper and waited 2 weeks and not a drop leaked. The storage is great-it's right there when you need it.
I got this because my sink drain plug does not seal well, and I prefer to put water in my bathroom sink when shaving so I don't constantly need to leave the water running or turn the water on and off to clean the razor. All I do is close the drain as much as it will go, and then put this stopper over the plug and the seal is perfect!
I bought together with &#34;Better Bath Deep Water Bath&#34; as I didn't trust either one alone to stop the slow dribble drain of water. The two together work great. Just know that you need to tromp your heel on the center suction of this stopper a couple times throughout your bath as I think the flow of tap water above it and maybe even a foot push now and then unseat it's seal.
Forms a very good seal, even manages to keep the tub full when I'm giving the dogs a bath, Easy to remove as well, which is a huge bonus. Only complaint is the little suction cup that is supposed to allow it to be stuck to the wall isn't strong enough to hold up the weight of the item, but who wants to stick a tub stopper to the side of the shower wall to stare at all day? ?
Was given to my parents as a gift, they said it works really well. Has a good seal and easy to remove
I got http is stopper for the kids bath tub and it works great, not a drop gets by untili pull it up.
I've been using this tub stopper for about a year and love it. I have absolutely no complaints about this. If you need a tub stopper, this is the one to buy.
This space efficient tub stopper really works. It literally just goes on drain and the water fills up in tub. It really keeps the water in place.
I was looking for a new tub stopper because our old one was holding a curved form that was not conforming to the drain well and allowing water to slowly go down the drain. This tub stopper is made out of very flexible rubber so we do not have that same problem. The suction cup on the side tab holds it securely in place but is easy enough to remove.
