Thetford 92814 Porta Potti 345- A Detailed Review

Aug 18, 2023

In the world of portable sanitation solutions, Thetford has made a name for itself with a variety of models tailored to meet a wide range of needs.

Among these models, the Thetford 92814 Porta Potti 345 which is sometimes described as their "marine toilet" but I personally don't know why.

It's just your standard chemical toilet that can be used for camping or any other portable application.

Here's the bottom line on this one...

This toilet is a low cost, functional toilet that will serve travellers, campers, and outdoor enthusiasts just fine *if* you are up for a chemical toilet.

This is a big *if* for many people who've actually used, emptied and cleaned a chemical toilet.

For the initiated, I'm just going to add this short video so you actually know what you're in for no matter which chemical toilet you buy.

Obviously, videos like this don't sell chemical toilets too well but this is the reality.

If you're ok with that, and you're happy with the price and capacity of the toilet, this toilet is just fine.

Just go to Anaconda, Tentworld, or any major camping retailer and grab one.

Before you do though, watch this short video and see what we sell:

Our toilet is WAY more expensive.

It requires that you buy bags on an ongoing basis.

BUT - you will never have to do the nasty task of what chemical toilets require.

In my mind, if you can afford the money, why would you add a dark stain (pardon the pun) to every camping trip by ruining your time away quite literally dealing with other people's shit?

Don't you do enough of that in life already?

Amazon Reviews

As always, we dive into the negative reviews and see if there's any valid design flaws that are consistent.

With this toilet, there's not much bad stuff from a design point of view that is consistently reported.

There are a few people that complain about the flimsy plastic or a broken vent valve or a plunger mechanism that's broken, but those people are in the minority. At scale, those kinds of things are going to occur to even the best products.

At the end of the day, this a toilet that sells for less than $200 in Australia.

What do you really expect for that?

In my view, this is a mass produced product that is made well for the price.

Here's a snapshot of the reviews anyway.

Here's a step-by-step guide to help you keep your toilet in the best shape:

Regularly clean the toilet to prevent build-up of waste or residue. Use mild detergents and a soft cloth or brush to scrub both the interior and exterior surfaces.

Avoid using abrasive cleaners or pads as they can scratch and damage the surface.

2. Emptying the Waste Holding Tank:

Frequency: Depending on usage, you should empty the waste tank regularly to prevent overfilling and odors.

Procedure: Ensure the flush tank is empty. Then, separate the waste holding tank from the flush tank, take it to a proper sanitary dump station, and empty the contents.

Sanitizing: After emptying, you can rinse the waste tank with a mixture of water and a mild detergent or a specific toilet cleaning solution. Make sure to rinse thoroughly before reassembling.

3. Refilling the Flush Tank:

Refill the flush tank with fresh water. You can also add a small amount of toilet chemical or deodorizer to reduce odors and break down waste more efficiently.

4. Check Seals and Valves:

Over time, the seals and valves of the toilet can wear out. Regularly inspect them for any signs of damage. If they appear worn or do not seal properly, consider replacing them to ensure efficient functioning.

5. Lubrication:

To maintain smooth operation, occasionally lubricate the seal on the waste tank with a silicone lubricant. This helps in preventing the seal from drying out and cracking.

6. Storage:

If you're not using the toilet for an extended period:

Empty both tanks.

Clean the toilet thoroughly.

Store in a cool, dry place away from direct sunlight.

Consider adding a small amount of toilet chemical to the waste tank to prevent odors during storage.

7. Avoid Harsh Chemicals:

Never use bleach or other harsh chemicals in the toilet as they can damage the seals and other components.
