Review: Quick Replacement - Ideal unit to replace our old one. Speedy arrival and all sorted / fitted within 72 hours Review: Lack of mounting bracket - Bought this as a direct replacement for leaking Aquasystem. Stupidly I did not realise that I could have purchased just the bladder but that was down to me. But what did annoy me was that the original one had a welded mounting bracket whereas this one has not. Consequently had to spend an additional £12. In retrospect I should have just used an old belt and a hook but I was in too much of a hurry and didn’t think of it. Having said all that, the tank appears to be fine. ## Features - DOES NOT INCLUDE BRACKET ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00QVM62A8 | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 205,236 in DIY & Tools ( See Top 100 in DIY & Tools ) 155 in Boilers & Accessories | | Certification | WRAS Approved | | Colour | White | | Customer Reviews | 4.4 4.4 out of 5 stars (86) | | Date First Available | 11 Dec. 2014 | | Item Package Quantity | 1 | | Material | Plastic | | Shape | Round | ## Product Details - **Brand:** Aquasystems - **Capacity:** 24 litres - **Colour:** White - **Material:** Plastic - **Specification met:** WRAS Approved ## Images ![Aquasystem 24 Litre Potable Expansion Vessel with 3/4" Connection - Image 1](https://m.media-amazon.com/images/I/41Ur7Vp-1DL.jpg) ## Questions & Answers **Q: Does this come with a fitting bracket? And can you post extra pictures of the other side (so I can see the temperature / pressure ratings etc?** A: No it does not, so had to purchase it separately using a large jubilee clip as nothing welded onto the vessel. Says 10 Bar and -10/+100C. **Q: Can this be used for unvented systems?** A: If you mean unvented hot water systems then yes, but not for unvented heating (sealed heating) systems. Check if this model has a mounting bracket otherwise you will need to purchase one. Also check the size of the inlet to the vessel - they are often 3/4", so you will need a 3/4" brass adapter if your pipe doesn't already have one (modern pipes are metric and will typically be 22mm rather than 3/4"). **Q: Is a fixing bracket attached to the vessel?** A: HelloThis vessel isn't supplied with a mounting bracket there is a version with a bracket clip on the back.Here is a link to our website on Amazon : http://www.amazon.co.uk/Aquasystems-Potable-Expansion-Integrated-Bracket/dp/B01BKE85HY/ref=aag_m_pw_dp?ie=UTF8&m=A3CDXZXWOMXNSS Alternatively you could buy this vessel and a wrap round type bracket to fix it to the wall and here is a link for this on Amazonhttp://www.amazon.co.uk/Expansion-Vessel-Bracket-sizes-Litres/dp/B00QVM4PAM/ref=aag_m_pw_dp?ie=UTF8&m=A3CDXZXWOMXNSSBest regards **Q: My existing expansion vessel screws directly into the top of the hot water tank (no bracket is needed). In this respect is it suitable?** A: You should check with the manufacturer of your cylinder. Normally they will have a recommended replacement part. Fitting another brand may stress the joint with the cylinder if the new expansion vessel is too heavy when mounted. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quick Replacement *by M***N on 18 April 2021* Ideal unit to replace our old one. Speedy arrival and all sorted / fitted within 72 hours ### ⭐⭐⭐⭐ Lack of mounting bracket *by M***N on 21 June 2020* Bought this as a direct replacement for leaking Aquasystem. Stupidly I did not realise that I could have purchased just the bladder but that was down to me. But what did annoy me was that the original one had a welded mounting bracket whereas this one has not. Consequently had to spend an additional £12.

Having said all that, the tank appears to be fine. ### ⭐⭐⭐⭐⭐ Under pressure! *by R***T on 16 February 2017* There's not a lot you can say about this product. It sits there quietly doing its job, typically with no maintenance and that's the only thing which causes them to fail. No one checks the air pressure (once a year minimum) and the internal diaphragm fails due to lack of pressure in the air side of the vessel. Check yours now and maybe you'll avoid having to buy one of these! ## Frequently Bought Together - Aquasystem 24 Litre Potable Expansion Vessel with 3/4" Connection - Santon Spare S6214 Expansion Vessel Bracket --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/50903175-aquasystem-24-litre-potable-expansion-vessel-with-3-4-connection](https://www.desertcart.vu/products/50903175-aquasystem-24-litre-potable-expansion-vessel-with-3-4-connection) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-17*
