Water coming out of a showerhead every time the tub fills can be annoying. With modernshower valves, the issue is typically that not enough of the water can exit the tub spout, and there can be a couple of causes. Here’s a helpful way to troubleshoot the issue.
How Modern Shower Valves Work
在确定问题之前,重要的是要了解现代淋浴阀的工作原理。这些阀门看起来像四向连接,从阀的侧面进入热水和冷水,并通过底部出口出口进入浴缸。该出口内有两个孔。较大的孔口提供水to the tub spout.
在正常情况下,打开桶槽,thewater simply flowsfrom the orifice and out of the tub spout. With the tub spout shut, the water backs up and travels back to the shower valve, passing through the smaller orifice. From there, it travels straight up and out of the showerhead.
Why Water Might Leak from the Showerhead
If the tub spout is open andwater is leakingfrom the showerhead, there are generally two causes. The first cause is that the tub spout’s guillotine-like gate is stuck or partially obstructed. When this is the case, all of the water cannot exit the tub spout, causing it to back up and overflow out of the showerhead.
The other possible cause is that there is simply too much water pressure for all of the water to exit the tub spout. When this is the case, the backpressure will cause water to exit through the smaller orifice and out of the showerhead.
Tub Spout or Water Pressure Issue: How to Tell
The easiest way to tell if it’s an issue with the tub spout or water pressure is to take the tub spout out of the equation. Do this by removing the tub spout from the plumbing, either with an Allen key or by unscrewing the tub spout, depending on the model.
Next, run the water at full force. If the water stops coming out of the showerhead, there is likely an issue with the tub spout itself. If water continues to flow from the showerhead, the system has too much pressure.
How to Fix Tub Spout or Water Pressure Problems
如果浴缸喷口是问题,请购买替换浴缸喷口并安装。测试它以确保其正常工作。如果淋浴喷头仍然随着新的喷口泄漏,可能是时候降低压力了。
If the pressure is the issue, there are some simple fixes. If the pressure in the rest of the house is okay and the only place high pressure is causing an issue is the shower, simply find the control valves and throttle them back slightly until the shower runs properly.
If the pressure is too high throughout the whole house, adjust the pressure-reducing valve until the pressure levels are more reasonable. This valve looks like an upside-down cone with a bolt sticking out of the top, and users can adjust the pressure by turning the bolt in or out.
