Leaking kitchen sink when full of water

[notchy]

Hi,

I need to confirm before I call a plumber if I can do the work myself or do I need to get a plumber involved.

I have taken some photos of the trouble areas I believe where my kitchen sink is leaking.
It seems odd to me but wanted to know if anyone experienced this before.

When I fill the sink up with water it leaks but if I have the water running it does not leak.

Underneath the sink I have taken a photo and it seems the rubber gasket is seperated from the sink and the pipe.
Can I get a replacement from a homedepot or do i have to go to the sink manufacturer for this and do it myself or do I have to hire a plumber. I can work my way around the plumbing a little bit.

So this is the link to the under the sink where the gap is between the rubber gasket and pipe.

This is the link where I have the arrow pointing to where the water reaches that level and it leaks.

Standard gasket and get yourself some plumbers putty.

Any of the big box stores will have a replacement gasket for ya.

in the centre of the drain, use a large flathead screwdriver to tighten the screw... if your driver isnt big enough, use a butter knife you dont care about... see if you can tighten it enough stop the leak...

failing that, you can buy a basket strainer at home depot... they are quite easy to replace and are less than $20

Take it apart, slap some plumbers putty and possibly a new gasket and away you go.

I will try this over the weekend

I will admit, I am not the greatest handyman...

The same thing happened to me this summer and I replaced it fairly easy, so it shouldn't be too touch. I would definitely not get a plumber. Just go to home depot and get the replacement kit and some plumbers putty. The rest is fairly simple. There are some how-to videos on Youtube as well.
