Red Sea Peninsula 500 Valve

[Zgraggen Bruno]

somebody knows the dimension (metric) of the ball valve (inlet) of a RedSea Peninsula 500. Would like to change the valve.

By inlet valve, do you mean the diaphragm valve on the main drain? Assuming so, it is 32mm.

I have the same tank and replaced the stock valve with a gate valve, which is much easier to control. I will be posting the details on my build thread later today, but in essence, I cut the stock drain line halfway along and used a coupler to mate the new parts.

Here is the stock part (the black line is where I cut the pipe):

Assembling the new gate valve:

The final part:
