Bio master thermo leaking

[Bolota]

Hi,
My bio master was off for sometime, and after rescaping my tank it started leaking. I can't diagnose the leak properly, but it comes from the lateral blue clips.
The lock/unlock switch of the taps always worked badly (always had to force it strongly to open). I contacted the vendor who told me I should lubricate the seals. I wonder if anyone experienced that?
What have you used to lubricate?

In my opinion, the bio master thermo is a good idea (integrating pre-filter and thermometer in one divide) but still badly engineered. It is noisy and the cleaning of the pre-filter still messy and not practical.
Meanwhile I returned to my old Eheim...
Cheers.

I’ve noticed that seals on some filters are of a specific non round profile so a simple O ring won’t work. This means OEM spare parts only I suspect. This is why I liked the old Eheim Classics, apart from the noise on the last one I bought.

Hi Everyone,

It's also advisable to check that things like Vaseline (petroleum jelly) are compatible with the gasket material. There are quite a few sites that provide this information.

How do you know what the O rings are made of? There’s no mention of it in the manual for my TetraTec EX600, it doesn’t even mention any lubricant.



Edit: According to this probably the safest thing to use is Silicone:

What you need to know about O Ring Lubricants

Silicone grease and lubricants aren’t just a nice to have for o rings, but they are a must-have. Here is some information on o ring lubricants and silicone grease.

Hi all,

Yes, I'm definitely going to build the hype up slowly for <"Pump in a Bucket">, before adding in lots of different <"variations on a theme">, <"James Dyson"> style.

Going <"too big, too early"> was the mistake with the Duckweed Index, that and not patenting a "new improved" duckweed.

You got beaten to it man. Meet the "pump in a tupperware":

Plumbers use it as well, it’s a standard lubricant for use on potable water.
