I have been using this Franke sink for over 12yrs. 1 big bowl and 1 small. Below got coating which i dont no what purpose till recently found out.

So far no rust, stain or whatever. Just use detergent to wash and it shine back.

Actually I don't no that at that time. And never hear before this brand. Just like the design and the functioning.

What is that square box behind the tap?

I don't see it difficult to change the tap either wall or sink mount. Sink mount is using a big nut to secure and wall mount is direct screw in. Both still need a tool to tight/loose it.

I think sink mount look better and have more advantage than wall mount. Sink mount look tidy. Can locate your tap anywhere and change your sink position is not a problem. Since the pipe hole at below and can use flex hose.

While wall mount is a bit ugly. Specially screw side to the pipe hole. Installer must aim nicelly to your sink. Otherwise your tap will out of position. Cannot locate your sink anyhow. Need to hack the wall and redo the piping if sink change position. Even a sink change will have problem.

You mean the tap screw thread that long enough compare to your table top thickness? For this kind of joint, the table top is ready with the pipe socket at the surface level. You need to search for the direct screw in tap. Just like the wall type. While wall type is 90degree, but the table top is vertical.

It is a bit ugly at the table top socket side with the tap screw. Try look for those with a cover that can coverup for nice finishing.

Left or right very much depend on the kitchen design. The tap is alway at the center bow. The small 1. I m using the big and small bow too. But the sink is already have a tap hole center. Just buy the tap and fix in. My big bow is at the left. Away from stove and beside the windows.

Sorry. Forget already. It is somewhere promotion warehouse.

I use top mount and love the sink very much. Guess I will use it in my entire life if it don't spoil.

If I throw it away, don't think I can get back that material quality.

Why so difficult to mount a sink? What is the reason your contractor given you that it easy to leak? Where will it leak?

Put the sink picture here, back and front and everything. What is the sink model.

Probably people here can help you.

I m using top mount sink for 18yrs. Not even a drip of water leak down till now. But it is a good sink.

Aiyo, pack like that how to see? Cannot brain what you mean aslso.

BTW, your picture model cannot find in teka website. Fake 1?

Try to open and see got rubber seal or not.

You no need to apply the whole inside. Just at the almost the edge is enough. Once to press on it, the seal will spread out. Wipe clean the seal that spit out.

I saw the sink like got some clip lock at the side.

I don't understand what you mean very very thin the contact. Can't see the picture sink properly how is the edge shape. Get a close up picture and the bottom side.

You can get the rubber from the ACE. Those door and window seal rubber. I forget the brand. Still have a roll in my store room.

This is my sink edge. Any similar? I don't remember it have a rubber seal or using silicon. But I cannot see any silicon seal on the whole edge of the sink.

The photo I post, end of the edge have flat surface and seal properly to the table top. The rim is also hollow.

What the rims curved upwards ?

Yeah. You remind me. RAVEN. This is the 1 I buy.

The rubber is very soft and compact in easily since inside is empty. So put on the heavy sink will compact in easily. (Won't lift up the sink) And it come in 2 seal. That totally seal out everything.

Hell. I don't want touch it. Once open and all the hell break loose. (leak)

Flat rim no need rubber seal la. It will lift up the sink and look ugly. And cut your hand if bump to it. Why not undermount?

The sink should have the clip and screw. It prevent the sink from move around.

Your 1 is only can seal by silicon. But silicon will get mold after sometime. Can't run away. Try look for any other sealant at least anti mold.

The rubber thickness must below 1mm. Even 1mm consider too high.

I check at RS catalog. There is a tape call Polyethylene foam tape. Thickness is only 0.8mm. Another 1 call Polyethylene carrier-Tesa 51968. Thickness 0.3mm.
