Sealing Membrane

for replacement of membrane inside the lid with opening (extra lid not included)

The sealing properties of this silicone membrane keep the urine canister closed from the inside, ensuring that liquid is unable to escape from the canister into your toilet and that any smells are kept away. Even if there is any splash from bumpy roads or tipping, this membrane stays put and keeps your space clean and smelling fresh.

If you are a full-timer using your Trelino® on a regular basis, the membrane should be replaced every 3 months in order to maintain the fit and sealing properties. For weekend warriors or part time users, this piece should be replaced every 6 months.

Scope of delivery

2 x silicone membrane (ca. 1.57 in.)
6 x silicone membrane (ca. 1.57 in.)
10 x silicone membrane (ca. 1.57 in.)

could be better

These start to stick way too fast, don’t fully seal, and often get pusehd down into the container when the toilet is reassembled. Wish there was a better option

Love Trelino!!!!

I used the Trelino system in my 4 month road trip amd am delighted with it. I reviewed it on my you tube channel. No odor!!

Works great

We don’t compost, but we do use a small sprayer of watered down vinegar. Number 2 gets taken out right away. Very happy with how strong it is as everything needs to be double duty so it’s also an extra seat and leg rest!

Not what I wanted

I need a different part. Apparently you don’t sell the connector piece separately.

We love our trelino

Thanks for making such a simple travel toilet

I LOVE my Trelino in my Sprinter Van.

Trelino® - Membrane closure

Toilet and spare membrane

Love everything about thes toilets.
Sturdy, well made and no superfluous.
Recommended them to my friends 😊

Garbage

This toilet just sucks in general. I’ve had it for about 2.5 years. This box smells no matter what video you watch our forum you read and try to fix. Lid breaks easily. The membrane always falls in the jug which requires you to either fish it out or dump it with everything and buy a new one. Regret spending $400+ on a plastic bucket.

Hi Zachary,

We apologize that you had these experiences. We would be happy to replace your lid for you and also offer advice for any smell issues you have been having with the rest of the toilet. You can contact us at hello@mytrelino.com to have these issues communicated and to be assisted.

Best,
Katie from Trelino

Quick delivery

I very satisfied with the fast delivery of my purchase. I will buy genuine products not Amazon to ensure the correct fit and convenience.

Life on the fly

I can truly say this is the best portable toilet on the market. Quality is amazing, product functionality is always well thought out.their customer service is always excellent.
I’ve recommended this toilet to all my camping friends and camping groups.

membranes

membranes wear out over time and must be replaced

Must Have Extras

this is a must have in the back up category because without it you will have spray and clean up, odor, etc. the unit is not useable (in my view) without it so I’m happy they sell extras!

It’s great, does what it’s supposed to do

Too flimsy

The membrane closures are too flimsy and keep falling through the hole. Not fun having to fish them out of urine or lose them while dumping.

Work well

These work well. I thought it would be nice to have an extra.

Nice that the membrane closures are available. Nice that they work so well at making this toilet odor free. Not so nice that they don’t tell you they need replaced every few months. Wish I knew this when I ordered the toilet, as it would have saved me the $20 shipping fee.

New Membrane gap didn’t seal completely

Our replacement membrane was easy to install but I noticed that the flat valve surfaces (where the urine enters the tank) do not close completely. There is a small gap which allows the odor to escape.

replacement bladder

I just don’t understand how these bladders keep on falling into the urine container. I don’t know if they get stretched out or I think I put them incorrectly. This new bladder fell in on day two and I almost lose them by emptying the container and flushing them down toilet toilets. So it’s a bit messy to try to filter them out when they do fall in. May I suggest some type of a string or silicone attachment so that it permanently won’t fall into the urine in the urine container.

Membrane closure

The package came on the promised date and the product was exactly what I ordered and does its job well!!!!

Timely shipping reasonable price 😉

Membrane lifespan

We love our Trelino, however the membrane closure on the urine container doesn’t stay closed for more than a couple of weeks. We’re on our second one.

The rubber pee valves are not like the original at the end they have a gap

Please advise if I've received 2 defective valves.

Hello Nancy,Thank you for your feedback and for bringing this to our attention. We’re sorry to hear about your experience. Could you please contact our customer service team at hello@mytrelino.com? To assist you as quickly as possible, we kindly ask that you include photos of the defective membranes in your email. If the item is indeed damaged, we will of course send you a replacement right away.
Please note that the membranes are always slightly open by design to prevent the membrane lips from sticking together. Additionally, this slight opening allows air to escape from the canister, preventing internal blockage when liquid passes through. Without this feature, there would be a risk of overflow. We hope this explanation helps clarify their functionality, and we look forward to resolving this matter for you promptly. Best regards, your Trelino Team.

I wish I could like this product

It’s honestly just really disappointing. It was so expensive and just not very good. The shape of the pee container makes it really awkward to empty, and the lidless poo container smells every time I open up the top lid. The membranes get pushed out of place sometimes when I put the lid back on, and sometimes they fall all the way in. It’s not because the membranes are bad, the whole thing is just not a good design. I’m afraid I’ve wasted my limited funds on this product.

Great composter

Small and easy to use, cleaning,dumping is a breeze

I keep extra.

I’m a full time rv traveler ( retired ) and I always try to be extra prepared as I’m not always where I can get packages delivered. I also like a clean environment so I’m so happy for a way to have things on hand I might need later. Thank you for having these available for my emergency parts kit. I’ve never lost one or had one damaged but I do like to replace them occasionally.

They are great!

Keeps smell in

We Like in ourCampervan, Mercedes Sprinter our Trelino!!!
How you clean the blue canister perfectli?
All the best Gabriella

Thank you for taking the time to leave a review. For cleaning the canister, we suggest using a vinegar or citric acid solution. Having too much water in the solution or cleaning with just water would lead to urine scale build up and smells. If you're noticing this issue, then you can adjust your cleaning solution to be more concentrated with the vinegar or citric acid. If you have any other questions, just reach out to us at hello@mytrelino.com and our support would be happy to help!

Quality product.

Back up membrane closure

First of all all, since purchasing and using the compost toilet, it fulfills all my uses and is very comfortable in my RV. I was originally concerned regarding smell but there has been none. The company has been very communicative with my re-ordering the membrane. This product and the customer service is very good.
