PURYTEC Heads Sanitiser

[Cantata]

Has anyone else tried one of these things and had problems with it? Generally available (I got mine from Compass), has a T-piece you insert in the heads flush-in pipe, and bottle of blue-coloured sanitiser screws into it. Fitted mine the other day when the tide was out, so couldn't try it then; we've just been out for the weekend, the thing is a major problem because it leaks like crazy. Almost seems as though the bottle thread doesn't quite match the thread on the connector, as when you try to tighten it up hard, it jumps off the thread and loosens again.
Seemed such a great idea, too. I'll be on the phone to Compass (not feeling optimistic about that!) in the morning but I wonder if anyone else has suffered?

I'm not a fan of inline "sanitizers"...they tend to be messy...effectiveness varies...some just replace sea water odor with an equally undesirable chemical odor...and the chemicals can interact negatively with holding tank chemicals.

The most effective "cure" for odor due to stagnant sea water in the head intake is also the easiest and costs the least: tee the head sink drain line into the head intake line. To flush all the sea water out of the head intake pump and discharge lines, close the intake seacock, fill the sink with clean fresh water and flush the toilet. Because the seacock is closed, the toilet will pull the water from the sink, rinsing out the whole system. Follow it with another sinkful to which you've added a cupful or two of white vinegar to prevent sea water calcium carbonate buildup in the lines.

It is necessary to keep the sink plugged when not in use...otherwise, the toilet will pull air through the sink drain, preventing the pump from priming.

I fitted one and found exactly the same initial problem. However, I found that when it was not overtightened it sealed OK and that was about 3 months ago. It does not stop all the smell from sea water in the inlet pipe after being left for a few days but otherwise seems OK. The best think I did to my toilet was to remove the handle and main piston and grease them with waterproof grease. All the problems of stiff and squeaky operation have completely dissapeared.

Peggy, I've read this advice of yours before and can understand it's a useful fix. However, while it would be a very practical solution if all the plumbing and seacocks were in the same small area of the boat, in my case they are not and there are long pipe runs with fittings not hugely accessible.
When I explained your ideas to the most important person on our boat, she wasn't impressed, so that settled it really.

Cantata, I have one fitted but didn't have any problems with the thread etc BUT in my experience of this inline 'sanitiser' are that they are a waste of money as all they do is make the loo water a nice blue colour - they DON'Tt get rid of any smells. The only way to get rid of smells after a period of non use is to fill the inlet hose with Fresh water, I do this with a Tee'd in hose led to a canister of fresh water. This has totally cured my Hydrogen Sulphide smell when using the toilet for the first time. The Purylator sanitiser had no effect at all. I also fitted 'No Smell' hoses but don't know whether they had any effect at all, but they look nice & clean.
