True for almost all appliances and electronics (if you want to use them longer)

Vinegar also breaks down the calcium and it's cheaper. Put vinegar in a plastic bag around the shower-head. Secure it with rubber bands all night. The calcium should be gone however if it's really bad, you might need to do that a few more times. Seriously, vinegar is AMAZING! Vinegar and baking soda

And if you've put something like that in the plumbing and called a plumber... tell them. Not uncommon for plumbers to end up in the ER for chemical burns...

Aaah! I'm learning a lot today.

I also recommend buying a single lever mixer tap. Those are very common in the northern Europe but in most other countries people still like to use two taps (hot and cold) and mix the right temperature manually. I have never understood why they still like to do that even though single lever mixer taps have been available many decades.

Put the roll of extra tape in the toolbox where you can easily find it, along with the flow restricted showerhead that you replaced with a 5-setting one. That way you won't have to buy new ones when you move. Then you can take your fancy massaging showerhead to the new place and install it there.

With plumbers Putty you can at least pull it up if it needs to be fixed. Silicon sets like glue

Not true for Moen. When I pruchased my house every plumbing fixtures were Moens and one day the shower handle broke. They wouldn't replace it without the receipt. When I told them it came with the house so I had no receipt, there was nothing they could do even though it says Moen on it.

I have seen similar showers at many American movies and TV shows and I have never understood how the people wash their private parts with those showers. Here in Europe most shower heads are hand showers so it is very easy to wash your whole body.

we kinda saw this earlier....
