Hi guys,
We have a problem with our pool : the water jets (return jets) are quite a lot less powerful than they used to be. My father noticed that by putting his fingers in front of one. Before, we couldn't even put our hands in front of it, because the pressure was very high. Now, we can put a few fingers a few inches in front of them and keep them there (with some force).
Relevant information and things we've done :
We have an approximately 60,000 liters inground pool, with a Jacuzzi Laser 250 filter. Water is supposed to be sucked in from the skimmer and bottom drain.
We figured maybe the jets are weak because the pressure isn't high enough, but the pressure gauge in the sand filter indicates 19-20 psi, which is apparently normal for an inground pool.We read online that air leaks could cause low pressure. We checked the o-rings : they look good. We checked for bubbles in the return jets and the pump strainer : there were none.
My father also noticed that when we put it on "Drain", the water shoots out on the street with less pressure than it used to.
We thought maybe the sand is so dirty that even though the pump is less powerful for some reason, the pressure still shows 20, but would show a much lower one with clean sand... but we backwashed, rinsed and even used a bottle of sand cleaner (emptied it in the pump strainer basket according to instructions on the label).
Now we're wondering : would it be possible that the pump (suddenly) loses power with time ?
If you'd like to have pictures or have us try something, please let me know.
Thank you !
P.S.: We tried to put it on "recirculate" (whirlpool) and the jets were still weak. Apparently, it seems that the sand filter wouldn't be the culprit here...
Also, some relevant info : according to my father, it seems that the water jets became less powerful a bit after we sanded our wooden deck (right next to our pool). and the pool floor was covered with wood dust.
