How do I fix a leaky pipe?

Question

The pipe that drains water from my tub is leaking, it's a rather large pipe.

Answer 1

Depending on where the leak is and type of pipe you are using. If the leak is on a straight pipe no matter what type, you can repair as Redbird's prescription, which I will elaborate later. If the pipe is PVC or uPVC you can cut for about 4" long and replace the pipe using two sleeves of bigger sized pipe and pipe cement glue.
As Redbird said, for straight pipe, you can purchase a set of resin that goes by the name "Thistle bond" or "Corda bond" and a roll of 2" glass fibre tape. The resin is supplied with a bottle of hardemer which you mix to the prescribed ratio. While the mixture is still hot from chemical reaction, apply it onto your leak and wrap it with the tape wound around the pipe for several layer while applying the resin in each layer. Let it cool and dry to certain hardness. Have a go. But make sure your work surface is dry before any repair.

Answer 2

You could fix it using this principle. I had a leaky hard plastic hose pipe that disconnected itself from a holding water tank. I pushed/folded the hose into an n shape then drew the two sides together and tied lots of string around them. That stops the pressure flow. BP could get some made-to-measure flexi-pipe and seal it over the opening of the leak and apply the above theory. I haven't used all the correct professional jargon. A plumber would know what I am talking about.

Answer 3

I forget what the product is called. There is a pipe wrap cloth that you wrap aroung the pipe. You apply a fluid of some type (and it may be as simple as water) and the wrap hardens and seals the leak. I have seen it used in chemical plants on high pressure lines sucessfully so it should work for you. I am sure it is sold in hardware stores.

Answer 4

From below the tub, most of the piping should be quick connect with large nuts you have to loosen to access the P trap. (The large U shaped pipe that holds water to keep sewer gas from comming into your house.) If it is one of thoes joints, replace the fitting(s). If it from the collar that sits in the bottom of the tub, that can be removed and repacked with plumbers putty. Hope this helps.

Answer 5

A leaking drain pipe is easy to fix. There is no pressure on it so anything that will stop water will work. Plastic tape, silicone caulk, anything. Now to repair it is a Little harder. you need to determine if it is just loose or if it has a crack in it. You might have to remove and replace it.

Answer 6

it might be as simple as tighting he drain pipe where it meets the tub if not id remove the drain and id put plumbers putty around top side of drain pipe then screw back to main pipe

Answer 7

You might be able to put some fiberglass blanket and resin on it, or rubber sheet and clamp (with some kind of sealant), or replace it of course.
