Ron,

 

I use muriatic acid straight out of the bottle to get thru heavy growth…

It's the only thing I have found that can cut thru the growth in the time that customers will pay for.

Standing around watching a pump run for a long time tends to run up the labor bill, and takes away from the time I could be at another job…

 

But again, because of the dangers of using it straight….I would never recommend it to folks to try alone, or if they are limited in experience…Just too many bad things that can happen with it…

 

For those that think they want to try it even after my warnings…Never inject it into a open system (like pouring it into a hose) Please make sure all connections/hoses/hose clamps are tight with no chance of leakage to anywhere but where you direct it to (it does need a pressure relief to somewhere)

At a yard I once worked for…We had a new guy that tried pouring it into a head discharge hose….

Well it Erupted !!! and before he could shove the hose back on the head it had sprayed everywhere in the Master cabin of a year old 54' Hatters MY (not to mention the burns he suffered) The whole cabin…Furnishings, carpets, bulkhead finishes, bed spread & mattress, valances etc…All had to be either replaced, or re-done by the yard…I'm sure he will never forget that one, and I felt bad for him because I guess he didn't know any better…But still it was a painful & expensive mistake that could have been even more tragic (like loosing his eyesight or worse)

ALWAYS HAVE A GARDEN HOSE WITH NOZZLE PRIMED & AT READY…When working around, or with acids !!!

Hi Dwayne,

I did some research (as you probably have already) about the Barnacle Buster system/s...

Yes I believe they are the same company/product that I dealt with when I was service manager for the Cruisair distributor here in St Pete Fl.

They had approached us about becoming a servicing distributor for them back in the 90's...

They also did a lot of brain picking if memory serves me...Their flushing products Port O Flush & Port O Flush Jr. seem to prove just that...

The products are very similar to what I have built myself, and have used for years...

For your application I would recommend the Port O Flush Jr. system ** you don't have permission to see this link ** 

The instructions for use are here ** you don't have permission to see this link ** 

You could also use the Port O Flush Jr. with Muriatic Acid (I Do) but as I said...Lots of things can go wrong like leaks, and thus someone getting acid burns, or worse yet, overtaken by fumes.

The obvious dangers are the damage acid can do to everything it touches...This is why I don't recommend it for DIY guys, and would never recommend they do it alone...

Another set of eyes and a garden hose with nozzle at ready is always best to dilute any acid that may leak immediately upon notice...and Believe Me...The fumes will put you on notice !

My feeling is you would be better off buying their Barnacle Buster product for the safety factor alone...It will do the job...Just plan on all day, and I'm sure you don't have the injection ports installed so that will take time & materials too...

If you have slip neighbors...Maybe you can get them to split the cost of the Port O Flush Jr. and share the unit with all involved...

It could save everyone $$$ in the long run and once they see it I'm sure they will want to borrow it...

Good Luck & Let me know what you come up with if you get a chance...

Steve,

You say to use acid with water to clean out the water hose on the system.  What kind of acid and what would the ratio be in the mixing it water?

Thanks,

Ron

The easiest way to clean water hoses is with acid & a pump…Problem is can the acid get to the problem ?

If the path is completely blocked by growth…you will need to at least clear a small path to get some flow to allow the acid to push the water out & get the acid to the clog/s

If the acid can't get there and bypasses the problem…Well neither can the cooing water, and herein lies the problem…

Simple answer ?….There really is not one simple answer due to the multitude/variation of plumbing installations…Each boat can be very different...

I have some customers (with multiple unit locations such as yours) that I have installed valves in different locations of the plumbing just so we can block off different sections or units...This way we can direct the acid to where we want, Meaning to the problem area so that it won't (the acid) just bypass the area that it is needed in most....The acid (and seawater) will take the path of least resistance. 

The only other option is to replace the plumbing which usually is not simple at all…

Is there an easy way (or what is the easiest way) to clean the water supply hoses?  I have a 1998 Searay with some after market additions to my A/C system (mainly a bridge A/C addition).  It has one pump and three self contained units as well as one split unit with one condensor and two air handlers (helm).  None of that is very important except to demonstrate the complexity of the supply hose routing and the access to each.  My pump has worn out, so I am in the process of replacing it, however in the procrastination time, there has been exremely low water flow in a nutrient rich warm water environment, sooooo... lots of growth in the sea strainer and presumably the lines and possibly the heat exchanger thingies.  Ihave tried to use fresh water to back flush, and it does net some growth, but not a lot.  Is there a tool (like a giant pipe cleaner) or something that I can use to ensure there is no growth in the hoses?  I will start using pieces of copper tubing starting tomorrow when I put in the new pump.  Thanks.

BTW, I just found this site, and as a do it yourselfer, the information is invaluableCool.  If you sell parts you have just icked up a new customer.
