Soak the showerhead before you replace it

Often the head, and people say to find out for the price of a bowl of vinegar before you decide anything else. Many people say what feels like low pressure is frequently mineral scale — limescale, calcium — blocking the nozzles — and one person adds the small mesh screen in the neck of the head, and that soaking the head in white vinegar, or a stronger descaling cleaner, and rubbing the nozzles clean restores the flow; others add the bag-of-vinegar trick for a head that will not unscrew, the toothbrush for the nozzles, and unscrewing the head every so often to tip out the grit and sediment that collect behind the screen. One person warns the stronger descaling products work but are harsh; another that the cleaning does nothing for a head that was badly designed or defective in the first place. People argue clean-first against buy-new: the clean-first side says it is cheaper and often the whole answer, the buy-new side says a cheap head costs less than the bother, and people’s own decider is what is wrong — scale you can dissolve, or a design you cannot. Two things the head cannot fix, from one person and from the gaps people name: how to tell a plumbing problem from a head problem is a gap people named; this page’s own rule of thumb is that if every tap in the house runs slow, the head was never the problem; and if the head is seized on and will not turn, one of the named gaps is exactly that, and the honest answer is a plumber before a wrench. One mistake people caught in their own words is worth carrying because it changes what you buy: what you feel is flow — the volume of water coming out — not pressure; a showerhead changes the first and cannot change the second, so a head sold for ‘pressure’ is engineering the spray, not the pipe.

Yes — many people say so, and one person says it made little difference. Many people say a new, better head is the effective, inexpensive change, especially in a rental or an older house where the fixture was bought on price; many people in one place and some in another say a new head solved what they had assumed was a plumbing problem, and some people say rental units come with heads so poor — a handful of holes, a spray that mists — that no cleaning fixes them. Some people say fitting one is trivial: the old head unscrews, the new one screws on, hand-tight, often without tools; others add a wrap of plumber’s sealing tape and a gentle turn with a wrench for a drip-free seal, and one person warns not to over-tighten, because the arm connects to a joint in the wall. One person says a new head made no difference even at the expensive end; people’s decider is the head you had and the head you chose. What to choose, from people and without the names they used: many people say a handheld head on a hose is the upgrade they would not go back from — you can rinse a child, a dog, a tent or the shower itself, aim it at your own height, and one person with a long back says it ended the crouch; others add that a head on a sliding rail or an extension arm fixes height for tall people, that a plumbing wholesaler’s brass version outlasts a box store’s plastic one, and that one person rigged two heads — a fixed one and a handheld on a long hose — for very little; one person warns suction-cup holders drop the head, and one person says magnetic ones do too, so screw the holder in. One person says the makers’ customer-service lines will identify and send out a spare part for nothing, which is worth a phone call before a new head. And for the head you replace: read the next question before it goes in the bin.

Keep it, and people mean in a bag in a drawer. Many people say the renter’s version of this page is buy your own head, fit it, and store the original to screw back on the day you move out; others say the head is worth taking with you to every flat you ever rent, and one person says they have done it with every place they have lived. Some people add the paperwork: tell the landlord or agent you are changing it, keep the receipt and a photo of the original in place, because one person warns some management companies charge a tenant for ‘replacing’ a fixture they never lost, and some say a landlord who finds a different head at inspection may accuse you of damage. One person puts the rule bluntly: leave a changed fixture in place at move-out and expect the deposit to pay for it. People argue the exception, and this page carries both sides. One person says the original is too disgusting to store and to leave the good head behind; some people say leaving a nice head for the next tenant is a kindness — one person does it on purpose — against some people who say you swap it back, always, because the lease is the lease and the deposit is yours; people’s decider is how strict your landlord is and how you feel about a stranger getting your showerhead. One person notes the landlord’s incentive: where water is included in the rent, a low-flow head may be there deliberately. And one line about the arm: it is the landlord’s wall behind it, so hand-tight only.

This is the argument, and this page will lay it out rather than tell you to do it. Many people say modern heads have a small plastic or rubber disc — a flow restrictor — behind the neck, put there on purpose to limit how much water comes out, and that taking it out makes the shower feel dramatically stronger; some people do it before fitting any new head. One person points out what it is for: in the US, a federal rule since the early 1990s limits a showerhead sold to about two and a half gallons a minute, and the disc is how the maker meets it — this page checked that, and adds that some states set a lower limit still. Now the other side, which is why this page gives no instruction. A plumber says it is not worth it: the water does not feel different, and the heater drains faster — some people note the advice conflicts; one person warns a small hot-water tank empties fast at full flow; another says it can wreck a well-engineered head or make the spray worse if your home’s pressure was already low; one says it raises your water and heating bills; and some people warn it may be against local water rules, your lease, a homeowners’ association or the head’s warranty, and one person warns that it may be illegal in some areas — against which one person says the federal rule binds the manufacturer and seller, not the person who owns the head. None of this is settled: people argue whether it is selfish where water is scarce, whether a low-flow head saves water at all when it takes longer to rinse shampoo, and whether the disc is the fix or a good new head is. People’s own decider, across all of them: your home’s pressure, the size of your hot-water tank, your local water rules, and your lease. This page’s own position, marked as its own: clean the head first, then buy a well-made head that is designed to feel strong at the legal flow — that is what the engineering in a good one is for — and leave the disc question to people who own their walls and their water bill and have checked their local rules. One US line for anyone whose problem is the opposite: one person says local utilities sometimes give away low-flow heads through efficiency schemes, and one person warns they may not suit you.

Then the head was not the problem, and people hand you to someone else. One person warns that if the flow stays weak after a clean and a new head, look at the water heater; one person says a shower that is never hot enough may be the temperature limiter on the valve cartridge rather than the head at all. The gaps people name are the honest boundary: what to do about a clogged pipe or low municipal pressure, a head that has seized on, and your legal rights to change a fixture in your particular lease and jurisdiction — people do not know and this page will not guess; a plumber and your lease are the two documents. Two small things people fixed while they were at it, one person each: a curved curtain rail stops the curtain blowing in and gives you elbow room, and a sliding rail or extension raises a head that was fitted for someone shorter. A long side of the discussion is an argument about how often anyone should shower at all; it is a different subject, and it is not here. And if you catch the cold water that runs before the shower warms, another page on this site has what to do with it.
