Leaky Baxi 105e

[v8chevette]

Hi all

I've got a leak on my Baxi 105e combi

I've traced it to the top of the 3-way valve.

It's leaking around the plunger that comes up and activates a micro-switch.

Does anyone know what the part number is for this and is it available seperatly or will all the 3-way valve need replacing

Cheers in advance

Is the pressure differential valve just the bit thats leaking or is it the full unit that needs replacing?

HI

it is the full unit ( not the diverter valve) it cost about£ 25-40
there is a diaphragm inside which could be damaged £5-10

Excuse me jumping in on your post, but I have exactly the same problem. I've replaced the diaphragm inside but it leaks just as bad as ever. I think the leak is coming from the bypass pipe that you can see going in at the back of the photo. This pipe goes in above the diaphragm, so the leak just comes out where the spindle comes through. Did you manage to fix yours, or can anyone help me with mine.
