Equipment Worth Asking About: Pumps, Salt, Heaters and Lights

Most people shop for a pool by the way it looks. The equipment that keeps the water clean, warm and lit gets far less attention, even though it determines how the pool runs every day. You do not need to become an expert, but you do need a handful of good questions. One of our customers put it well in a review, saying that Hilltop used top of the line components that the reviewer would never have thought to ask for. This article covers the items worth raising before you sign a proposal.

Pumps: why variable speed is worth a conversation

The pump moves water through the filter, the heater and the chlorination equipment, and it is usually the largest electrical load on the pool. A variable-speed pump can run at different speeds instead of one fixed speed. Running slower for long hours is gentler on the equipment and on your electric bill than running fast all day, and slower flow tends to be quieter. We will not promise a savings figure, because it depends on the pool and the settings. Ask your designer which pump they specify and why.

The same review that praised the equipment mentions a variable speed pump with thermo mode. We would not want to guess at how a particular pump implements that setting, so ask your designer how it works on the model they plan to install. Here is exactly what the reviewer wrote: "they use top of the line components that I would have never thought to ask for. Like a variable speed pump with thermo mode to the quality of the liner and salt generator to the concrete backed liner instead of steel backed."

Salt systems and what to know about phosphates

A salt generator produces chlorine from salt dissolved in the pool water, which many owners find gentler on skin and eyes than handling chlorine by hand. It is not maintenance free. The cell needs checking, the salt level needs watching and the water still needs regular testing. Our own blog has pointed out that phosphates and salt systems do not mix well, so if you are leaning toward salt, ask how phosphates will be handled and tested. A good designer will have a straight answer ready.

Heaters: more than a comfort feature

A heater lets you extend the swimming season and bring the water up to a comfortable temperature on a cool morning. Heaters come in different types, and each has trade-offs in how quickly it heats, what fuel or power it uses and what it asks of your property. The location of the equipment pad, the gas or electrical supply and the size of the heater all need to be planned with the pool, not added afterward. We have written about heater installation on our blog because it is a decision people tend to leave until the last minute.

Lighting that earns its place

Pool lighting is both practical and part of the design. Good lights let you use the pool after dark and show off features like waterfalls and edges. Placement matters as much as the fixture, since lights that glare into the house or leave dark corners can disappoint. Ask to see where the lights will go, how they are controlled and how a lamp or fixture is serviced. Lighting is one of the custom features we include in our process, so it is easy to discuss at the proposal stage.

How to compare equipment in two proposals

• Does the proposal name the pump, the filter, the heater and the sanitizing system, or only describe them in general terms?
• Is the pump variable speed, and what does your designer recommend for the way you will use the pool?
• If you want salt, how will phosphates and water balance be handled?
• Where will the equipment sit, and is it easy to reach for service?
• How are lights placed and controlled?
• What is covered by the warranty, and who do you call if something fails?

Equipment decisions are easier when they are made early, alongside the design, instead of being squeezed in at the end. They also tell you something about a builder. When a proposal explains why each component was chosen, you are probably dealing with people who have thought it through.
