Review: High Quality - Easy Install - First well mate tank lasted 20 years. No brainer to order another one. Quick connect for water manifold makes installation a snap. Make sure to follow instructions, tank cannot be put horizontal, has to have a minimum of a 30 degree angle from horizontal. Made in USA. Review: Same basic deisgn as old tank, new quick disconnect makes it easy. - The quick disconnect made the replacement of my 10 year old tank a 10 minute job. I cut the old fixed pipe from the old tank and unscrewed the remaining portion, screwed in the new male end with quick disconnect and slid tank on. Fill to the correct air pressure and re-energize your system and open valves. Spent more time cutting up old tank to fit in trash can than installing the new one. ## Features - Quick Connect, Replaceable air cell assures easier field servicing. - Greater drawdown than comparably sized steel tanks yields greater efficiency. - Extended labor warranty option is available to homeowners. - Won’t rust in corrosive environments, particularly important in coastal regions. - Quicker and less costly to install, usually requiring only one person and fewer man-hours ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B016SEHF3Q | | Assembled Diameter | 16 Inches | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #99,495 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #23 in Hydraulic Tanks & Reservoirs | | Customer Reviews | 4.5 4.5 out of 5 stars (115) | | Cutting Diameter | 16 Inches | | Date First Available | March 1, 2011 | | Is Discontinued By Manufacturer | No | | Item Weight | 28.6 pounds | | Manufacturer | Wellmate | | Material | Fiberglass | | Part Number | WM-9/WM0120QC | ## Images ![Wellmate WM-9 / WM0120QC Captive Air and Retention Fiberglass Tank, Quick Connect (29.5 gal / 112 LTR.) - Image 1](https://m.media-amazon.com/images/I/41zPKkMCwpL.jpg) ## Questions & Answers **Q: How do you know what a good size tank is ?** A: This is the one my professional mechanical contractor sized for my 3000' square foot 2 1/2 bath house. It's been flawless for 20 years and I decided to replace it because after that time the bladder must be leaking to some extent. That and a new well pressure switch, and I'm like new again. **Q: Does this have the quick disconnect?** A: Yes it has a quick disconnect and they give you a spare one also.. **Q: How tall is this tank?** A: 43" **Q: This may be redundant as the q was ansered on the tnank u end. q. could a schrader valve be replaced with a digital read-out?** A: No ## Customer Reviews ### ⭐⭐⭐⭐⭐ High Quality - Easy Install *by K***E on January 30, 2023* First well mate tank lasted 20 years.
