No leaks! ### ⭐⭐⭐⭐⭐ A no-brainer item when installing a smaller hot water expansion tank. *by C***E on March 25, 2025* If you are using installing the smaller hot water expansion tank, (and have a little space on top of your hot water tank) then this is a no-brainer for an easy install. Install this, using a 3/4" dielectric nipple on the female end on top your hot water tank. Cold water input goes to the horizontal 3/4" male threads. (For an easy cutoff - use the SharkBite Max Stainless Steel Corrugated Flexible Water Heater Connector that offers a very nice ball valve available here on Amazon.) Lastly, install your tank on top. Looks professional. ### ⭐ Leaks *by S***S on May 23, 2025* This products is well made and of good quality. However, it leaked. I did follow the instructions instructions (the box has a QR code tag you scan with your phone to download the manual), and I tried multiple times and it didn't matter how much I tightened it. I decided not to use it and instead I used just a regular bronze tee coupling. I didn't need the 360 degree swiveling after all, ## Frequently Bought Together - Eastman 3/4 Inch Brass Swivel Expansion Tank Tee, Fits 2-10 Gallon Tanks, 26090Z - Eastman 60022 60022/DET-5 2 Gallon Expansion Tank, White - MEASUREMAN 0-200 PSI Water Pressure Gauge, 2-1/2'' Dial, Hose bib Pressure Gauge, Home Water Pressure Tester, Durable 3/4” Hose Thread, Water Pressure Gauge for Home --- ## 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.hr/products/637493217-eastman-3-4-inch-brass-swivel-expansion-tank-tee-fits](https://www.desertcart.hr/products/637493217-eastman-3-4-inch-brass-swivel-expansion-tank-tee-fits) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-20*
