Where can i find plumbing parts in Krakow? ( Rearranging plumbing to install a dishwasher )

I am trying to rearrange the plumbing under my kitchen sink to accommodate a portable dishwasher. To do this, I will need to install a new waste arm or an extension for the existing waste arm (PVC). I have two questions:

1) What is the Polish translation of 'waste arm'?
2) Where can I find such a device in Krakow?

I have looked at Obi, Leroy Merlin, and Castorama - each to no avail. While these stores have minimal piping and plumbing supplies, they do not offer what I need. Any suggestions of a specialty shop in Krakow (or possibly on Allegro) that might offer several sizes and lengths? Thanks!

I'm afraid we don't have such thing. It is assembled from pipe and elbow.

You need kolanko pcv 50mm, rura pcv 50mm x lenght and trójnik pcv 50mm.

I actually have one installed under my kitchen sink here in Krakow (see photo). The waste arm has a number (636.37/1), but I have no idea how to utilize this information - a Google search yields nothing pertinent.

I only need to add 10 cm to the length, so I guess I could simply add an extension - but one more connection adds another possible place for leakage.

You were spot on, Peter! I checked Praktiker today and found a kit that includes the waste arm that is installed under my sink. However, I believe it will be impossible to find different sizes of this piece - so I guess I need to improvise.

I need to add 10 cm or so to the pipe - is it possible to cut the pipe near the middle and install a connector of some sort between the two pieces? It's a 40mm pipe.

I don't understand fully what you going to do. Why don't you use this little inlet on vertical pipe?
Classic connection looks like this. It has to be a tight connection, rubber hose with clamp.

The compact dishwasher is too wide to fit under the sink with the plumbing in its current position, so I must move the vertical pipe to the other side of the wall pipe. Thus, the waste arm needs to be lengthened. I fully intend to use the existing inlet for drainage from the dishwasher.

Do you know anything about electricity? There is no electrical connection under the sink, so I will need to run a heavy-duty extension cord (about 3 meters long) to the unit. I know what to buy in America (a cord with 12-gauge wiring), but I don't know how to find something equivalent in Poland. Any suggestions?

You need cable 3 x 2.5mm2 and standard household socket, rated 16Amp.
if fixed on the wall Przewod 3 x 2.5mm2 drut i gniazdko natynkowe z bolcem, podwójne.
if just an extension przedluzacz 3 x 2.5mm2

Peter, you've been most helpful - thank you very much for your advice. This should do the trick (do you agree?):

You seem to know what you are talking about - may I ask your opinion about my dishwasher installation? In America, we typically connect our DW to the hot water line - however, it seems that Europeans typically connect theirs to cold water lines. The owner's manual for my DW says to hook it up to cold, but a manual from an different DW (from the same company) states that you can connect it to the hot water line, but it will be slightly less efficient than using cold water.

Here's my question: I receive my hot water from an outside source (an electric plant in Skawina provides all of our heat and hot water). Purportedly, this is significantly less expensive than using a traditional water heater. Because of this, I believe connecting my DW to the hot water line might be more efficient (and cheaper) than heating cold water with the DW's built-in electric element - do you concur?

Maybe it is not a real photo but cable looks too thin to me (probably 3 x 1.5mm2) Weight it in your hand. The heavier the better.

I'm not enthusiast of connecting it to DomesticHotWater outlet but they say:
- It is 49'C to 52'C (in some locations 43'C after 23oo) but may reach 65'C (5'C more than DW warranty terms)
- some say that lack of cold water = not such clean and shiny glass

That all makes sense - I will connect it to the cold water supply per your suggestion. Thank you for all of your help, Peter! If you ever make it to Krakow, let me know - I'll buy you a beer.

I'm coastal animal but thanks :)
