Correct thru hull for lectrasan?

I was talking to a marine sanitation guy here locally and was told that he did not carry or like the lectrasan's because their output was too corrosive and it would eat the thru hull fitting right off the boat. He claimed to have seen boats nearly sunk by this situation and that it was not uncommon.

I've been around for awhile and not heard that previously. I would think that given the open nature of the thru hull and the limited time that material passes through it, that it would not matter much.

But...turns out that I need to rebed the discharge thru hull anyway as it has started to weep over the last few months. So, since I'm going to have it out, it would be just as easy to change it out. Currently it is a heavy bronze thru hull.

1.) Should I?

2.) If so, what material would be ideal? Would this be a job for Marelon?

Thx.
 
Sounds like only Vic could answer this but I find it hard to believe because if I am not mistaken in full ocean salt water the LectraSan doesn't use anything but the same amount of salt that is contained in sea water. It does however make me wonder about the PuraSan which uses an Oxidizer similar to Chlorine. I use a heavy bronze thru-hull. Sounds like an urban legend.

Sounds like total BS to me. I've lost count of the number of boats I've maintained with Lectrasans on board and I've never seen anything like that.
 
Second boat with LectraSan; 22 years total. Have had no problems along that line whatsoever. Used original thru hull fittings that came with boats for overboard discharge.
 
The Lectra/San and it's godchild, the Electro-Scan, are celebrating 35 years on the market this year. In all that time, I've never heard of one causing a boat to sink - or even threatening the integrity of the through hull or other plumbing fitttings, or any other part of a boat.

Yes, they work on an electrolytic principle, but that is only while they are running, 2 minutes at a time. And any residual capacitance inside the treatment tank bleeds off within a very short time.

As Capt Bill said, it's simply not the case. A lot of your "old time mechanics" get a half-baked idea stuck in their heads, particularly when they don't fully understand how something works; then over time, it becomes Gospel to them. Sorta like everybody's crazy Aunt Sophie, who swears that black cats really do attract lightning.

BillyIII, the same applies to your Purasan. They are quite popular on aluminum-hulled houseboats, where corrosion and electrolysis are more of a concern than on other boats. No problems to date. The Purasan came out in 1994 or 1995, and we haven't sunk any boats yet. The halogen solution is quickly dissipated once it gets out into the water, and we haven't had any complaints or problems about it.

When replacing a through-hull fitting, always use the best grade naval bronze (not brass or red brass!) that you can find.
 
Yeah...well that's what I thought but I thought I'd throw it out there for comment anyway. Every once in awhile there is some kind of truth to go along with the myth.

By the way, is it all black cats or just females?
 
Thanks Vic, I really wasn't concerned as much as curious. I have full faith in Raritan's research and development. The PuraSan works like a charm and the Elegance is the best head I have ever had or used in a boat. Top notch products with great support and built in America! Even in New Jersey one of the worst if not the worst state to operate a business in. Keep up the great work.

Billy, thanks for the kind words! We can't buy that kind of advertising.

Regarding the business climate in New Jersey, just remember - come November, be sure to vote for ABC !!!
