I'm replacing the mechanical seal on an Emaux pump. The Youtubes I have watched mention not to touch the ceramic part of the seal. Too late. So my question is then also, is my seal already wasted, or can I just clean it, and if so what should I use to clean it? Would 70% Ethyl alcohol do any harm?

Issue seems to have resolved on its own in the meantime. I still hear the remote sound of air escaping in the filter valve when pump is off, but everything stays 100% primed. Any suggestions of what may have been the cause are welcome. The sound of air escaping, means air must go somewhere...

Sorry I don't have pictures. Please read the OP of this thread for more clarity on my setup and the previous issue. I had a problem with air leaks at suction side for the past week, though when I had that issue the SWG would not drain at all. I fixed the previous issue this morning by...

Yes of course I get some gas coming out of the return jets, but I think you are overlooking something. This has nothing to do with the SWG. If I just let the pump only run for a few minutes, the cell housing is full when I turn of the pump. Thirty minutes later, the cell housing is empty. The...

When the pump cycle ends the cell housing is full. It drains slowly over the period of 30 minutes. It also happens if I do a cycle without chlorinating I can also hear a sound under the lid of the multi port valve This started today, on a 10-year-old system, right after I had solved the air...

I had air in the system earlier this week, where after ending a pool cycle, within 1 hour the feeding pipes would run empty, while pump and cell housing would remain full. Thread is here Need help with air in system I got that sorted, by greasing the o=rings from all ball joints - check valves...

Let me add this, as it can be useful info. It happens for a while that the cell housing turns half empty at the end of a filter cycle, but there is no real problem with the pump sucking are on restart. The problem started a few days ago when I decided to shock the pool. I cleaned the pool...

Yes I did, but my understanding is that if there are leaks at the suction side, there will be visible bubbles under the pump lid, which I don't have. It is also a mystery to me how an air bubble can build up somewhere in the system, which is obvious when I restart the pump after an hour, while...

My setup is Zodiac Tri SWG - Hayward Superpump II 1.5Hp and 28" top mount Hayward filter Equipment is at pool level and right at the pool. The feeding tubes go vertical for about 80 cm, then connect to the tube that feeds the pump, which is horizontal for about 1 meter, then goes down 45° to the...

I did another backwash, and now the problem is less, but it still exist, so it is definitely a pressure issue. I have 2 cycles a day, one 3 hours and the other 4 hours, where the air bubble after the 3 hour cycle now is not big enough anymore to trigger the "no flow" warning light. The pump is...

I did check the valve, in fact I used a valve I removed from the jacuzzi pump, which has no issues there.

To do this test I assume a Taylor test kit should be used. I don't have this, and I have also never seen one available in Thailand, so i use the Aquachek 7 test strips. I don't notice any irregularities in my chlorine levels, and I test about once every 2 weeks. Last backwash was about 6 weeks...

Not sure if I understand your explanation correctly, but to be clear there is no air bubble in the cell housing during the cycle, the air bubble is clearly visible rising from under the cell housing as soon as the pump stops running. It has worked fine for 7 years, and only started a few weeks...

Yes the pictures are not really clear. A 2" pipe which feeds from up to 3 different feeds goes to the 1.5Hp pump all in the back of the pump house. The feeds are Skimmer - vacuum and main drain. From the pump a 2" pipe with a vertically mounted check valve goes to the filter. From the filter...

Please see if you can explain this. A filter cycle is 3 hours. The pump get activated by the timer in the Zodiac Tri, so cell and pump get switched on and off simultaneously. When a filter cycle ends, immediately a few big air bubbles will rise from the return line into the cell housing...

Thanks for the reply, and what you say is correct. I worried that the coating on the cell might get damaged when not soaked in water for long time

The big air bubbles rise from the return line that goes to the pool below the cell housing. I do not think there is a leak in the piping in the pump house, as that would create bubbles in the pump or the cell housing during filtering, or maybe even some water leaks, but none of that is visible...

Managed to make some picks

Another update since the problem still persists. I have removed the check valve on the return pipe of the filter, because it would constantly make noise, as if it was opening and closing constantly. The check valve is of the spring type and mounted horizontal right at the outlet of the filter...

I want to add, the pump draws water from bottom drain, skimmer and vacuum. So since it are 3 separate feeds I doubt it the water supply is insufficient.

Bit complicated to make pictures right now, but thanks for trying to help. My filter is a Hayward S310T2. As said I have a return valve between pump outlet and filter and a cl;osed tap on the waste pipe I also have added now a check valve on the filter outlet pipe., right at the flter. I...

Hi I have an in ground pool with Zodiac Tri, Hayward 1.5 Hp super pump II and hayward filter. I have a check valve between pump outlet and filter, and a closed tap on the filter waste pipe. I checked the check valve and it is not blocked. When I finish a filter cycle, there will come one big...

I doubt anything but the basic 2 tube Chlorine/pH tests are available here, but I also want to avoid liquid or test strip kits especially for something that needs to be tested so infrequently. In case I wasn't clear in my OP, with optical meter I have a refractometer in mind. They are...

Until lately I used a digital TDS meter to test my salt. I knew about how much dissolved solids are in my well water, and deducted that from the result to get an estimate how much salt the pool contained. Now it seems the meter starts to be inaccurate, so i have to order a new one. I notice...
