You said a local plumbing

and you do NOT want brass, you need bronze
Lastly it’s very common and a good idea for the intake to be larger then the exit, that’s to ensure that the pump
never has to pull much vacuum, if it does then it can cavitate and it will look like you have air in the output line.
That’s also why it’s the same way on the strainer.
no i think that was another poster.
ok great to know. i wont mess with the way its setup then.
fittings are just dinged up, dents in the hose side connection, mashed threads, dinged threads. i figured since i have it all out of the boat
and in pieces it would be a good time to replace them. i did break one fitting. you can see what they looked like and why i wanted to just replace them all. luckily groco still sells this one.
i tell you im really becoming a barnacle buster convert. i know its not the only product that descales but im realizing how important it is to make sure the entire raw water
system gets descaled, not just the heat exchanger
side. i always was diligent about cleaning
my strainer but after taking it off and disassembling it all, the buildup in the connections and inside the top bronze portion of the strainer thats not visable was shocking.
eventually i did end up cleaning
all the parts after soaking them in barnacle buster for a few hours. the fittings cleaned up nicely. i love bronze. im going to look into the fittings according to the info Brewgyver suggested and if i can find them save the older ones as backups i guess.
