    Hi I'm just wondering is it a good idea to run a line of silicone along the top of my shower
    It's a mira qt. Its fitted on a stud wall.I was thinking water might get down the back, thanks

    Assuming the shower area has been tiled correctly & shower fitted correctly, should be no need

    It states in the instructions not to do this. The Mira rep tried to tell me that this is why Mira (only mira) showers dry out, crack and break. They say its nothing to do with the cheak plasticity they use. Using silicon might voi the warranty on mira showers

    If the shower was installed correctly then the only hole behind the shower is a 2 or 3 inch hole for the pipe and cable. This is what you should seal with silicone and not around the shower. However if you have a huge hole or gap behind the shower then you will have no choice but to seal top & sides with silicone and take your chances with the warranty

    You would think a bit of silicone on top couldn't affect the heat dissipation
    It still has the sides for cooling

    Mira showers crack and break with or without silicone. They use cheap plastic but they like to blame the silicone. The problem I have is that the cover & plastic cover over the inlet valve don't fit correctly for the way most plumbers plumbed in the first place. This leaves an ugly gap on the bottom left of the shower.

    The instructions clearly state that the pipe should NOT come straight out of the wall & into the shower. It should come out in a soldered elbow & down into the inlet valve. They push this as a DIY product yet part of the installation uses soldered fittings! The cover that fits over this will accommodate a soldered fitting but use a nut & ring or come straight out from the wall & you get ugliest gaps.

    Only around 1 in every 50 mira showers we come across have been installed with a soldered fitting.

    The diagram shows a soldered elbow. The installation instructions for the elite 2 & elite St actually states only soldered elbow. They don't give enough room in the tunnel behind the shower for a nut and ring & 10mm cable. Soldered fitting doesn't have a nut & ring in the tunnel behind the shower.

    Pipe coming straight out of the wall and using none soldered fittings push the plastic inlet cover out from the wall leaving an unsightly gap. This gap becomes black with carbon dust after a while

    Diagram shows a elbow. Bear in mind this comes from england where they solder alot.

    You could also use a swivel elbow or a female elbow. Wouldn't stick out

    How many DIY people have even heard of these fittings? This is my point. It's sold as a DIY product (even though it's illegal for the homeowner to install) but they made it difficult for non plumbers to install. Had they made the tunnel behind the shower & the inlet cover only a few millimetres bigger it would cover DIY mistakes. This is an issue installers have been telling mira since 2000 with the launch of the Mira Elite 2. This has been a known issue for almost 20 years now and they haven't fixed it!

    More half of miras are installed with the inlet going straight into the wall. About 3/4 of miras are installed incorrectly. The Mira Elite Qt is very unforgiving of bad insulation
