Its a 1.5″ bushed out to 1.75″ to accept the raw water alarm. The mixer is 1.5″ as well.
Since posting the fluid drip on the lift pump has stopped. So, I don’t have a picture to share. I’ll just keep an eye on it.
I installed the raw water alarm on the end of the circuit. I figured there be less of a chance of large pieces (say impeller blade) fouling the alarm switch. My 6BTA -M3s have the 1.5″ raw water circuit. I was able to use reducers to make it work.
Any issues or hazards you can foresee with this install? Thanks
