Clean thru-hull from the inside?

I'm thinking of doing something similar in my boat. The through hull would be 2 inch and provide all raw water needs for boat, engine, generator, water maker, ac, etc. If the stand pipe going up was a hose instead , would that make the install less " dangerous" ?

Yeah, it is the long lever that makes this dangerous. But if this is a sea cock that is normally left open, you'd better install a ball valve in the top of the tee.

You gotta love the guy that did the bottom paint job.

I know this guy! He's the same one that scraped off my knotmeter impeller along with the barnacle growth back in the 1980's.

There is also a flush kit that hooks up to your air conditioner coils that has a decalcifier to clean those pipes that will clog over time...

Even though I'm a regular CF member I use the search function (but this thread came up on a google search). As such I will add to this old thread in case someone else knows how (I copied and pasted from a different related thread so it doesn't have total in the order of this one):

Well I connected a 4' clear hose onto the AC raw water inlet with a funnel on the open end and hung in the air to be above the water line. Filled that with a 50% mix of water and muriatic acid (hydrochloric acid) and poured into the funnel then opened the valve so the acid mix flowed down the hose into the scoop. Shortly I could ctap floating to the top of the hose and started getting bubbles up the hose. When the bubbles stooped and/or seemed to get real small and slow down I would pour morer acid mix down the hose to renew the mix as the bottom. I did this for about 2 house then flushed a lot of water down the hose and then blew in out using the wet vac a few times.

After the water going out the valve was MUCH better!!!!! Connected back up and turned in the AC and MUCH better water flow. Shut the outlet for the fwd AC and ran just the aft (because that one is higher up and was shutting down on high pressure) and forced all the pump flow through it, which flush a bunch of dirt out.

I'm happy as it worked and I didn't have to go into the nasty water here.

Still going to get a hose fitting and install on line to be able to flush with the dock hose to hopefully blow mure dirt out. I bet a lot of dirt settled in the lines when the flow was low.

I've attached a garden hose from the dock to the inside of the peacock, turned on the water, and opened the peacock. Worked great to force some reverse flow and clear out debris.

I hope that was an autocorrect mistake. It won’t be easy to get that image out of my head.

got the fittings and will give it a try tomorrow

I'll post how wide it makes the peacock spread its' feathers
