Dommage je voulais faire une installation neuf avec un joli montage. Et je me suis rendu compte que la pression d'air ne tient pas un mois. Très déçu,je pense acheter un VRAI ballon. ## Frequently Bought Together - 100L INOX/Stainless Steel Pressure Tank Vessel Expansion Domestic Waterworks Pump EPDM-Membrane - 80-100L Replacement Membrane Pressure Tank Vessel Expansion for Domestic Waterworks EPDM --- ## 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.us/products/674676490-wiltec-100l-inox-stainless-steel-pressure-tank-vessel-expansion-domestic](https://www.desertcart.us/products/674676490-wiltec-100l-inox-stainless-steel-pressure-tank-vessel-expansion-domestic) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-10-06*
