HOA pool or beach rinse shower upkeep for boards: flushing against Legionella, backflow devices, freeze protection, drains, water use and a season checklist.

Part of the HOA board handbook: vendors, projects and upkeep.

The short answer

A deck shower looks like the simplest fixture at the pool. It is also a dead-end water line that bakes in the sun, freezes in winter, gets a garden hose screwed onto it, and drains onto a surface where people walk barefoot. Each of those habits causes its own kind of trouble. Give the shower an owner, usually the pool contractor with a line in the scope of work, and a short list of checks. Flush it before opening and weekly during slow stretches. Keep a backflow device on the line. Drain it before the first hard freeze. Keep the drain clear. Rules vary by state, county and the community's governing documents, and your county health department decides what your pool must have. This guide is general education, not legal advice.

What the state pool rules say

Texas. The state pool rule, 25 TAC chapter 265 subchapter L, lists pools run for property owner associations as Class C pools (section 265.182). The same section defines a rinsing shower as one on the pool deck for removing sand, dirt, sweat and hygiene products without hot water or soap. Section 265.187(b) requires every part of a pool's water distribution system to be protected against backflow and back siphonage with a high hazard device, such as a reduced pressure principle assembly meeting ASSE 1013, or an air gap. A shower teed off the pool equipment supply is part of that system. Florida. Section 514.0115(3) of the Florida Statutes exempts pools serving homeowners associations of 32 or fewer units or parcels from most state supervision, but not from water quality supervision. A larger association should assume its pool is a permitted public pool. Construction standards for public pools are in section 454.1 of the Florida Building Code. Ask the county health department whether your approved plans show a deck shower. If they do, expect the inspector to look for a working one. Colorado. The state regulation, 5 CCR 1003-5, calls a pool used only by residents and their guests a private pool and exempts it. Local health and building departments can still set rules, so call both before adding or removing a shower.

Keep water from sitting in the line

Legionella, the bacteria behind Legionnaires' disease, grows in warm, still water, and a shower turns the water in the pipe into a spray people breathe. CDC's toolkit for building water systems says the bacteria grow best between 77 and 113 degrees Fahrenheit and can grow at temperatures as low as 68. A short pipe feeding a deck shower in July sits in that range most of the day, and on a quiet weekday the water in it may not move for hours. CDC tells building operators to eliminate dead legs, which it defines as sections of pipe with no or low flow, and to flush low-flow runs and dead legs at least weekly. Apply that to the shower: 1. Before opening day, run the shower at full flow until the water coming out is cold supply water, not warm water that sat in the pipe. Stand to the side while it runs. 2. In season, flush it weekly during any stretch of light use, such as the first and last weeks of the season and long rainy spells. 3. Clean or replace the showerhead each spring. CDC lists showerheads and hoses among the parts to clean regularly, because scale and biofilm build up inside them. 4. If a second shower was removed years ago, have the plumber cut its branch back to the main and cap it there, not at the deck. A capped stub under the deck is a dead leg. Log each flush with the date and initials next to the chemical log.

Protect the drinking water from the shower

The shower hangs off the drinking water supply, which is why the backflow piece matters more than it looks. TCEQ's guidance for Texas water systems defines backflow as any unwanted flow of used or non-potable water back into the drinking water system. It also notes that state-approved plumbing codes require hose bibb vacuum breakers on the outside faucets of new homes. A deck shower is often the closest water source to the pool, so sooner or later someone attaches a hose to it and drops the other end in the pool to top it off. If pressure drops on the main, that hose can pull pool water back into the line. What to do: - Find out which backflow device protects the shower line. It may be a vacuum breaker at the fixture or an assembly at the pool equipment. Write the make, model and location in the pool binder. - If it is a testable assembly, ask the water utility whether it wants an annual test report, and put the test date on the board calendar. In Texas, TCEQ says only testers it has licensed may test and repair assemblies. - Do not let anyone attach a hose to the shower, and say so to the pool vendor in writing. - If the shower post has a hose bibb at its base, fit a hose connection vacuum breaker or have the plumber remove the bibb.

Freeze protection and the spring start

An outdoor shower freezes before anything else at the pool, because the pipe is small and often runs up an exposed post. A split fitting inside the post may not show until spring, when water starts leaking into the deck base. North Texas, Colorado and the Florida Panhandle all get hard freezes. At closing, the pool contractor or plumber should close the supply valve, open the drain on the shower side, open the shower valve and leave it open so any trapped water has room to expand. If the shower has no drain, ask the plumber to price a stop-and-waste valve or a frost-proof valve. One cracked post costs more. Tag the shut-off with a label. Volunteers turn over, and the next board will not know where it is. At opening, close the drain, open the supply slowly and look for drips at the post, the base and any joints in the deck. Then do the opening flush. Our guides on opening the HOA pool for the season and closing the HOA pool for the season cover the rest of those checklists.

The drain, the pad and the runoff

Most complaints about deck showers are about the floor. A shower with a clogged drain makes a puddle that grows algae and tracks wet sand across the deck. - Keep the shower over a grated drain. Pull the grate and clear sand and leaves weekly. At a beach shower, a gravel pad or sand trap at the base keeps the drain from silting up. - Check that the pad slopes toward the drain and away from the pool. Shower water that runs back into the pool carries sand and sunscreen with it and adds work for the filter. - Scrub the pad as soon as it turns green. A slick shower pad is the likeliest fall at the pool. - Know where the drain goes. Some tie into the sanitary sewer, some into a dry well and some into a storm drain. Ask the city before allowing soap or shampoo, because water in a storm drain may go straight to a creek or pond.

Water use and heated showers

A shower left running wastes more water than anything else on the property. EPA's WaterSense program says a standard showerhead flows at 2.5 gallons per minute and a WaterSense-labeled head uses no more than 2.0. At 2.5 gallons per minute, a shower left on for four hours uses 600 gallons. Two cheap fixes help: a push-button metering valve that shuts itself off, and a WaterSense head. During drought restrictions, check whether your city treats a pool shower as outdoor water use. Most deck showers are cold, and the Texas definition of a rinsing shower assumes no hot water. If yours has heat, it needs more care. CDC's toolkit says to store hot water above 140 degrees and keep circulating hot water from falling below 120, and water that hot can scald. A thermostatic mixing valve lets the heater run hot while the shower delivers warm water. CDC lists mixing valves among the parts to clean and maintain regularly, so put the valve on the plumber's annual visit and have them check the temperature at the head.

A season timeline, a sign and the mistakes

A season might run like this. March or April: the plumber or pool vendor de-winterizes, checks for leaks, cleans or replaces the head and confirms the backflow device and any test date. The week before opening: full flush, drain cleared, pad scrubbed, sign posted. Weekly in season: clear the drain, confirm the push button shuts off, flush during slow stretches, log it. Closing: supply off, line drained, shower valve left open, shut-off tagged. Sign wording the board can copy: 'Rinse off sand and sunscreen before swimming. No soap or shampoo. Do not attach hoses to this shower. Report leaks or a slow drain to the board at [email].' The mistakes repeat. The shower is in nobody's contract, so nobody drains it in the fall. The pool vendor runs a hose off it every week. A broken shower gets pulled and the line capped at the deck, leaving a dead leg. A clogged drain becomes a green puddle by August. Name the shower in the pool service contract, with flushing, head cleaning, winterizing and drain care, and most of this goes away.
