Sand in Sight Glass - Pool Sand Filter 

I started to follow your videos I think you are slow and accurate in explaining things to people the way they can follow . Thank you I hope you have more videos on pumps and sand filters as well.

Is the sight glass removable to clean the rinse is not cleaning the sand or algae.

Hi, I just watched this video about the filter and looked at some of the questions to see if there was mention of the same problem and noticed there were no responses. So I've subscribed. Hope I can get an answer to my question. Thanks.

I have had an issue with sand getting back into my pool and as I watched your video, I am wondering if the issue is due to what you are describing. I have a TAG 100 that holds 600 lbs of sand. I was noticing sand in my pool last September (2023) and had a company out that replaced the sand and laterals. The old laterals and standpipe were not damaged but I had them replaced anyway. My multiport valve was 13 years old so I replaced that myself and had the company check it out to make sure it was installed correctly. It was. Fast forward to this Spring and I am opening my pool. We got a heavy rain and I ran the backwash for about 10 minutes to reduce amount of water in pool; then restarted the pump. Its a variable speed running about 15-18 lbs at the multiport gauge on faster setting. I did not run the rinse after backwash (never have) and noticed a lot of sand in the pool. Not sure if the problem I have is similar to what you show in the video? I did not quite understand though in your video, how sand would work its way out of the waste/backwash line into a return in the pool though. How does that sand, that should only be in the waste line get back into the return lines?? Did not understand that in your video. Second related question: should i continue to see sand in the sight bubble as the level of the sand gets lower. Thanks.

I backwashed for a few seconds then i rinsed and now when i run the filter im getting sand in the pool alot of sand

So it's ok that my sight glass has no water in it?

Is it normal to have no water flow back into the pool when filtering and pressure is low yellow?

We had a brand new pool/pump. I backwashed like you showed and there is still sand visible in the sight glass. Pressure on gauge also not lowering. Not sure what I am doing wrong.

Hello I purchased Quickrete 20/40 graduation Swimming Pool Sand at my local pool store. I add the sand to the pump. Add the chemicals a couple days after that . I back washed it like I didn’t rinse it the first time I didn’t realize that the second time there was too much water in the pool so I empty some of the water through the skimmer and then I back washed it to get some more water out and then I rinsed it . I did it for about minute but there is still sand coming out of the pump into the pool. So I’m not sure if I need to redo that process again but I can’t do anything until Sunday because of adding the chemicals so I had to wait for two weeks. Hope I didn’t confuse you but this is all new to me first time pool owner. I keep noticing after I vacuum and the next day there’s a little bit more sand so I’m not sure if I didn’t do it right the first time so any recommendations for me. Thank you

I keep finding sand at the bottom of my pool and its a brand new Intex pump. Intex sent a new top piece (valve) and pipe (not laterals). I replaced both and sure enough, sand still in the pool? I'm so frustrated. I am using #20 sand. Any help would be very appreciated.

I just noticed my sight glass is leaking - but mine has holes in the tip - with a little piece of rubber that flaps around when I'm backwashing and sometimes it covers the holes but most of the time water is coming out during the backwash process. My water level seemed to be going down so I went to check the pump and noticed water coming out the holes. WTH???!!!! I'm going to check the o-ring/gasget now as well, but it wasn't leaking from around the connection...

Ours fill with sand. It’s a new install, but my husband hooked it up before I got home from work yesterday. Not sure if it’s happening because we didn’t backwash the pump first, but woke up this morning and sand was standing in the bottom of the pool and sand is coming out in the backwash. I’m at a loss because I paid $450 for this thing.

So I just bought a new house with this intro pool and sand filter. I’m so lost and frustrated. First ours has not been used in a year and has quite a bit of sand in glass. Also I’m staying at zero psi on my gauge. I dumped the sand and am buying new tomorrow. When I hook it up it is pulling water from pool and pushing it back in just fine. I’m just so lost with what to do the pool is full of water finally after draining but is super cloudy! Please help is needed?

Can you remove the glass

Can anyone help me we have not been able to hold a suction and have the same problem on 2 different sand pumps it might filter right for 5 Minutes or for 20 we have checked all o rings all connections lubed up even plumbers tape we have backwash and rinsed over and over cleaned the sand we also have been vacuuming up sand on the return side but this morning after a backwash there was about a gallon of sand on the ground any suggestions like I mentioned before 2 different sand pumps are doing the same as in loss of suction

Can the spy be taken out and plug the hole for a short time while I wait for a new spy glass

Thank you for the video!

Is the sight glass removable to clean by hand the rinse cycle is not cleaning the sand or algae out.thank you

What if there is just a little bit of sand in the window?

I have a brand new sand filter and still have sand in the sight glass after a few bachwashes and rinses. How do I know if I bought the correct sand?

My looking glass has a small amount of sand and it empty’s of water. Isn’t it supposed to always be filled with water?

Bought the pool in March it was working well. Last week i started noticing sand in the pool after a backwash. I see it on the sight glass and doesn't clear out after the rinse. I'm getting frustrated and I'm thinking it's the laterals..... But not sure cause the system is new since March. Intex 2100 GPH Any advice.

We have a leak at the small jar sight glass and it doesn't want to budget to come out any recommendations on how to remove it to reseal it?

If you have sand in the glass and it's a lateral or pipe issue; will it also cause your pump to run at a lightly higher pressure? Mine is running in the yellow but not rising either.

My sight glass has algae... (green) .... how do I clean this?

My sand pump does have a sight glass can I install one and how
