Pool Pump Growlng And Sounding Like It Is Gargling Rocks?


Pool Pump Growling.....
Sounding Like It Is Gargling Rocks?

In this case, the water doesn’t usually fill up the pump basket. That is called “Cavitation”.  Cavitating pumps make a particular growling sound, like the pump is gargling rocks, a low, grumbling sound. Pumps need a full water flow to operate properly.

Poor water flow can come from: 


1.    A pump too big for the water supply so it can’t fill all the way up.  Bigger is not always better.  Be sure to have the right pump to fit your plumbing or enlarge your plumbing to match the size of the pump that you want.
2.    Plumbing pipes that are too small to deliver enough water to the pump.
3.    Broken directional valves
4.    Broken check valves
5.    Too full pump basket (too much debris)
6.    Debris stuck in the impellers
7.    Debris stuck in plumbing lines
8.    A dirty filter also is a blockage that you can control by cleaning it regularly.
9.    Leaks in the system that the incoming water can’t keep up with.


If this cavitation continues for long, it can ruin your pump.  Too little water means your pump is running “hot”.  This is not an issue covered by warranty since it is not something your pump can control.  It is up to you to provide the necessary amount of water to the pump.  A lack of sufficient water means a hot pump and can lead to a ruined pump…….also the noise is not pleasant, but it is a clear warning it needs help!

A pump that cavitates also uses excessive amperage, resulting in wasted energy and high energy bills, and because it's overworking the motor, premature failure is likely. 
 For help discovering which problem you have that is causing your pump to cavitate…..call Doug!

Pool and Spa Main Drain Repairs

While it is often referred to as a main drain, the main drain in your pool or spa doesn't actually let you empty your pool or spa. Instead, this 'drain' allows for water to be pumped out of the pool and through the plumbing system. Water that exits through the main drain is often sent through a filtration system that is controlled by your pool or spa pump and returned via your pool or spa jets or inlets. If something should go wrong with your pool or spa main drain such as a clog or cracked pipe, this can lead to some major inefficiencies with the rest of your pool's equipment. Since the main drain is usually located at the lowest point of a pool or spa, it may not often get as much notice when something goes wrong. To help you determine when it's time to call for pool and spa main drain repairs, take a look at some examples of common issues listed below. Increased Suction Sometimes a main drain will remove water at an accelerated rate because another one

Tree Root Problems With My Pool, What Do I Need To Do? This truly is a very extreme picture of damage tree roots can do to your pool, your deck, and your plumbing! Most of the time, the damage is much more subtle.   You might have a higher water bill (roots cause leaks).   You might notice that your salt cell can’t keep up with the chemistry (leaks caused by roots have the effect of taking the chemicals with the water running out)   We have had tree roots undermine and break up concrete pool decks, we’ve also seen roots come right through the pool walls, skimmers, tile, coping, and actually grow down the plumbing lines. I swear that some tree roots can "smell" the water in the pool, and make a beeline for it, stretching it's branches out until it pokes a hole, and busts up the floor or walls of your pool.   Usually you will notice something is “strange” long before it becomes this severe.   The first warning you may have is that your pool starts lea

Cleaning vs Replacing Waterline Tiles

A great looking swimming pool is always a positive feature on any property. Like a fresh cut lawn or a newly painted house, a pristine swimming pool is an eye-catching feature that will improve the overall appearance of any yard. Over time however, certain parts of your pool's appearance may start to decline. Waterline tiles are often prone to some type of deterioration over time. In many cases, proper pool care and regular cleaning can help maintain your pool surfaces, but eventually you may need to replace your waterline tiles entirely. To help you determine when its time to replace or simply clean and/or repair the waterline tiles in your pool, take a look at the helpful tips written below. Sun Damage Over time, waterline tiles exposed to direct sunlight will start to fade. While some tiles are more resilient against sun damage, eventually the regular exposure to sunlight will give your waterline tiles a bleached and faded appearance. Not only do sun damaged tiles look
