T&T: A/C pump - intake - problems/Remedy?

Install a back flush fitting to the AC raw water inlet so that a raw water 
washdown hose can be fitted when needed.

I am an above water kind of guy and love marine life when it surfaces or see 
it on the TV.  Diving under the boat is not an option most anytime, unless 
it is a real emergency.
So...
Since the Ac intake is vulnerable to clogging, mostly when not under way, 
wouldn't it be a good idea to install a tee with a hose fitting or such 
above the seacock for the AC intake....and maybe an additional valve above 
it to force a washdown pump and hose flush down and out the intake strainer?
Unless someone thinks this is a bad idea, I am going to install my intake 
that way since I am adding marine AC.
