Replacing Pool Equipment: What to Ask About Salt Systems, Pumps and Heat Pumps

Pool equipment rarely announces itself until it quits. A pump starts to scream, a heater won't fire, a salt system flashes a light you've never seen before. Then you're asked to pick a replacement quickly, in the heat, with the water getting worse every day. A handful of questions, asked ahead of time, makes that decision much easier.

Start with what the pool actually needs

Before brand names, work out the job. How big is the pool? Is there a spa, a waterfall or a cleaner that needs its own flow? Do you swim in the cooler months? Equipment that fits the pool beats equipment that only fits a budget. A pump that's too small leaves water stagnant, and one that's oversized wastes energy and strains the plumbing.

Bring the model number off the old unit, or better, have a technician look at the equipment pad in person. Pad layouts vary a lot, and the right replacement depends on the pipes, the filter and the controls already there.

Variable-speed pumps

A variable-speed pump can run slowly for long stretches and speed up for jobs like vacuuming or feeding a waterfall. Running slower generally uses less electricity and makes less noise than a single-speed pump going full tilt, which is why energy efficient pumps are a big part of what pool stores sell now. We carry them.

The trade-off is that a variable-speed pump has to be set up properly, and not every older system has the controls it expects. Ask whether it will work with your existing automation, and who programs the speeds. A good pump set up badly does less for you than an ordinary one set up well.

Salt systems

A salt system doesn't give you a chlorine-free pool. You dissolve salt in the water, and a cell turns it into chlorine as the water passes through. Owners like the steadier sanitizer level and not hauling jugs home. But the cell, the salt level and the rest of the water chemistry still need attention, and salt water can be hard on some stone, metal and pool features.

Before you commit, ask what your deck, rails, lights and any natural stone around the pool will tolerate. Also ask what the cell needs over time and who services it when it stops producing.

Heaters and heat pumps

A gas heater warms the pool quickly and works whatever the air temperature. A heat pump pulls warmth out of the surrounding air, heats more slowly, and is often chosen for efficiency in a mild climate like central Florida's. Which one fits depends on how you swim: a few warm-up days in the cooler months, or a pool kept comfortable all season. Say so plainly, and ask whoever is quoting to lay both options side by side.

Why a warranty service center matters

Mannix Pools & Grills is a certified warranty center for most major manufacturers. Our list includes Pentair, Hayward, Kreepy Krauly, Compool, Goldline Controls, Aqua Rite salt systems, Zodiac and Jandy. In practice, that gives you one local shop that knows each manufacturer's process when something covered fails, instead of a phone tree you have to work through on your own.

Warranty terms differ by manufacturer and by product, so ask for them in writing before you buy. Also ask about parts. We keep a complete parts inventory, we can repair just about any pool problem, and we'll special-order an item that's not in stock. A pump you can get a part for right away is worth more than a fancier one that sits on back order.

Questions to take with you

• Is this the right size for my pool and the plumbing I already have?
• What does the warranty cover, who honors it, and where do I take the unit?
• Will it work with my current controls and automation?
• What maintenance does it need, and how often?
• Can you show me the old unit and explain what failed?

The last question matters more than it looks. A good technician leaves you knowing something. Customer Carolyn McVicker wrote that our tech "educated me on the proper setting of the valves and proper filter cleaning," which is the kind of thing that keeps a new piece of equipment running well.
