Shower Head Flow Restrictors - Size Data ?
Looking at the old problem with de-limiting the water flow in a modern
shower head. The new one I bought, a Delta Supreme, has a standard five foot hose with an anti-siphon valve at the top end and a plastic insert at the handheld end. The hose appears to be 5/16" ID, the anti-siphon end has a set of eight 5/64" holes, and the plastic insert is 1/4" ID. By my calculations, the hose has an area of 0.077 in2, the anti-siphon piece has a total open area of 0.038 in2, and the 1/4 inch fitting has an open area of 0.049 in2. At a water pressure of about 70 psig, should I assume that the 1/4 inch restriction (or the even smaller multi-hole restriction) will limit the water flow to below 2.5 gpm, or should I be looking for something else even smaller (more restrictive)? Just thought I'd ask before I started drilling. - Magnusfarce |

Not a great deal more, but just enough to work well. -- Joseph Meehan Dia 's Muire duit |

Just thought I'd ask before I started drilling. I don't believe in any restriction at all in the shower head. Such restrictors invariably lead to a setup where the slightest water use anywhere within 100' will cause the temperature to fluctuate wildly. When I find such a restriction in the shower head, I remove it. The place to control water flow is at the hot'n'cold spigots or at that all'in'one jobby. I guess some don't have a flow control; is yours one of those? |
