He added some valve to make it "more silent" but there was little to no height in the flame... So i said what about a whistle free flex line... he told me "oh no its not that its just that pressure is too high"........ IDIOT! I bought this, installed it myself, MAGIC the obnoxious whistle is gone and i got a HUGE flame! IDIOT CONTRACTOR! ### ⭐⭐⭐⭐⭐ Perfect solution to a whistling firepit!!!! *by C***8 on Reviewed in the United States on December 2, 2019* Your browser does not support HTML5 video.  My firepit installation was amazing!!! The noise.. not so much. I didn't even consider the whistling effect of the hose. After installing this hose... 99% of the whistle is gone. There is only a slight "whoosh" sound when the gas valve is fully open. You really can't even hear it over the flame. What an upgrade!!!! If you have a whistle going on, don't hesitate, get this!! ### ⭐⭐⭐⭐⭐ HIGHLY RECOMMENDED!!! *by G***5 on Reviewed in the United States on May 24, 2016* HAD to fix the whistle in our new firepit usage. It was driving us crazy not being able to enjoy the flames and company with the noise always a deterrent. It was an easy fix once the works were undone and this replacement hose was installed. There is only a super tiny bit of noise at the very highest degree of gas volume but overall this was a blessing to find and I wish the original installers of our backyard haven would have known/recommended it's usage vs. us trying to solve a problem after building was complete. Would highly recommend this line for a peaceful solution to anyone who has experienced this whistling noise while using their gas firepit. --- ## 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.sg/products/203207838-36-x-3-4-high-capacity-gas-flex-line-premium](https://www.desertcart.sg/products/203207838-36-x-3-4-high-capacity-gas-flex-line-premium) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-07-07*
