Back to the silicone hoses. Is the 3x7 or 5x7 the best for the BM50?

Used this one in my previous BM20.
But... it doesn't fit in my BM50 (2015)

Just wondering.

Keen to get my wort fountains issues sorted, considering Polymax silicone edging strip for the top filter plate, if I fit 3018101 1.6mm to the top filter plate only, during pump breaks the top filter plate will stay fixed, the fine mesh filter will drop with the grain, there is nothing to keep it level during the drop and rise, possibly flopping about allowing grain to past the fine mesh filter causing issues?

Would it be better to fit 3018102 2.1 mm over both the filter plate and the fine mesh filter?

Has anybody done this?

It does stay level - least it always is when I open it.

Did start off trapping the mesh and plate together with the seal. But gave up on that lately.

I did consider a 3rd plate, to address this issue but never got there.

I think the issue is the pump is not 'that' powerful when everything is flowing well.
When he gets backed up, and then finally releases is when you get wort fountains

Weird, it does on my BM50 2015. That's without the fine mesh.

On my last two brews it seemed that some small malt fragments had blocked up the pump during the boil (it ran fine during the mash). This meant I wasn't able to circulate the wort to speed chilling with my immersion chiller, not the end of the world though! This from Polymax seemed to work well on my latest brew:

Silicone Edging Strip To suit 2.5mm Trans [3018103] 2 £9.50 (ex vat)

Two meters was enough to do the top and bottom plates on my BM20 holding the coarse and fine plates together. The seal did move slightly on the top, but no fountains and no blocked pump either.

FYI - I went ahead and bought the Grainfather silicon gasket.
The item delivered looked skinnier than the photo in the original post.
It did not work too well :( - the channel is too tight to stay in place on the edge of the filter plate.
It kept on working itself loose

I used some silicone hose - cut down one side. Never been a problem.

For a BM50 you could do exactly the same. Measure the gap and buy tube with that wall size.

I used silicone hose that has a 2mm wall - the diameter doesn't matter.

Here's an idea from another forum to prevent grain escaping from the malt pipe when/if you sparge or when you remove the malt pipe. It's basically a piece of SS braid placed over the center rod after the bottom screen have been installed and prior to adding the grain. When you remove the malt pipe the braid stays in place and basically collapses on it self preventing grain from washing out of the whole where the center rod used to be

That's interesting.
My grain bed is quite compact by that point but I see the point. I guess you could also thread it onto another piece of rod as it comes out.
