Which siphon should be chosen for an old metal bath. There is a big plus
This siphon is suitable not only for old plumbing, but also for new ones, it is convenient to work with it. To clarify, then it's not the siphon itself, but the cuffthat comes with it. But, drew attention to him when he was working with old baths, they often have a rust hole for the drain hole, there are "eaten away" sinks, and a standard gasket may simply not cover them, even if you work with silicone sealant.
Cuffed siphon
From the photo, you can see how it works, if the usual (blue) gasket provides pressure only from below, then the cuff is inserted into the drain hole and squeezes the walls from all sides in a circle.
It is a pleasure to work with it, so I began to install it on any bathtub or shower tray, and I recommend it to you, you will not regret it.
I have there were cases with old cast-iron bathtubs, where rust "eaten away", and only with the help of this seal was it possible to solve the problem. Such plumbing is usually found in poor old people., and this method will help at least gain time to save up for a new thing.
As you can see from the photo, when pressing the upper grill with a screw, the seal expands, filling the free space, who invented it is worthy of respect! Did you know about such a cuff in a bath siphon set?
