I live in Haiti and we use plastic tanks on the roof for gravity-fed water in the house. We are putting in showers in a new house and brought shower fixtures from the US (the type with a single, rotating handle in the middle of the wall). We have piping for hot and cold water, but only the cold is hooked up right now. The water comes in to the pipes with a lot of force, but when it's fed through the shower valve, the flow diminishes to almost nothing. We're told that inside the valve are a series of diaphragms that cut down on the flow and that this type of system is only usable with a pressure pump. Is there any way we can use it with a gravity-fed system? We hate to waste what's been bought, but we don't have 24 hour electricity to use a pump. Thanks for your help!
We took out the inner white plastic piece in the valve and it works, but won't shut off.
What is the make and model of the shower valves?
American Standard CADET Model # XXXXX or 1675 (ours does not have the tub fixture). We bought it at Home Depot. The inner part we tried removing is the pressure balancing unit. It improves the flow, but doesn't turn the water off when the handle is put to the off position.
I will do some checking and get back with you.
According to the directions the 1674 comes set to the Hottest setting "0". You can adjust it at the red ring according to installation instructions to the Coldest setting which is "7". Have you tried resetting it to these numbers. This should allow the cold water to flow without the Hot setting trying to overrule it. If these are set you should be able to turn it off at the valve.
