DO you have a metal case wrench as my plastic one is not strong enough. Brian

Hello, I'm very sorry but we only carry a plastic wrench. In most cases, this should be able to open the housings. If possible, you can try opening the nearest faucet to help relieve pressure. This may make it easier to open the housing. If you need further assistance, feel free to contact us directly by calling 1-800-880-4808 or e-mailing us at info@apecwater.com. We are in the office from Monday-Friday from 8:00am-5:30pm PST. Best Regards, APEC Customer Service
