I recently installed a spin filter and a 10" triple filter system in our well house located 10 meters away from the house. The filters were placed right after the pressure gauge tank. Gauge displays 2.5 bars/28 psi
Since then, all taps in the house (hot/cold) will show a slow flow decrease in pressure and come to a full stop after about 20 secs when opened. Close the tap again, wait few mins .. the water is back and slowly goes to a stop again and so on. Almost no water in tap upstairs (direct well water feed)
I also noticed that the cold water tap is jamming (air locks in the pipe??) could this be a loss a pressure in the tank that needs adjustment. ?
appreciate if someone could help troubleshooting that scenario.
thank you!
 
If the filters are after the gauge then it's most likely the filters are blocked.
You need a gauge after the filters to keep and eye on when they need changing.

the filter system and the cartridges are new. The spin filter is placed before the inline system. There is no real strong water flow when i start flushing that filter ...
 
Pulsating? Bursts of water in unequal sequence?
strong bursts is the term i was looking for .(excuse my french) then water eventually starts flowing normally (at the start) the slowly decreases to a full stops. This applies to the kitchen tap water (direct from well)

You saying the kitchen tap water is direct from the well or via the filter system and are you in the uk?

the kitchen tap water is direct from the well and the filter system.. I am in Ireland.I will get a picture of the system tomorrow

Think we need photo(s) of this system to advise.
got them this morning. First gauge reads2.5 bar, the second on the spin filter= 2.0bar.
Our well recently collapsed and a new one was bored before Xmas. (You can the pipe coming from outside) . Until the new well got bored, we were pumping a large amount of sediments and we probably still have a cheer amount of it in our pipe at home...

Do you have an expansion vessel in the system? If so, I suspect the bladder has ruptured!
Yes we do in the attic. could be the bladder did not like the amount of sediments that it was exposed to lately. However, it was working fine right before I installed the inline filtration system. One way to check i suppose would be to temporarily refit the pipe the way it was before...
 
The White cylinder in the photo, was it like that before or fixed vertically to the wall.
(Before anyone jumps down my throat I know some can be horizontal)
 
I think i should try re-connect the way it was and remove the filters to rule out potential blockage in it.
Question : if the tank gauge reads 2.5 bars, is the air pressure sufficient ? could it be that i need to add pressure ? I was purging the tank prior to fitting to the system as i suspected to be full of sediments..i don t remember what was the actual gauge reading before.
 
So I removed the cartridges that appeared already plugged up. Flushed the spin filter. Re-Opened the tank valve. Filters very slowly fills up. There is also little pressure when I flushed the spin filter.
I wonder if there could be someone wrong with the well pressure tank.. It looks like it is empty (i could easily lift it up) ..Could it be that I need to re-pressurize the tank although it reads 2.5 bar at the gauge ?
 
Ok I re-connected the pipe the way it was prior to fitting the filtration system. Pressure is back to normal and now have water. I guess there was some sort of blockage in the spin filter fitting and/or the entire system caused dramatic pressure drop. I will need to investigate the matter in the good time. I am done with plumbing for now. Thanks for helping out.

Your symptoms were classic blocked filter strainer behaviour. The pressure is not affected, the flow rate is affected by the restriction. with the tap closed, the system fills/comes up to pressure, a tap is opened and the flow is initially good and then fizzles out because the supply cannot keep up with demand.

I'm glad you got it sorted but for anyone who has a system displaying this behaviour at the outlets, strainers and filters are always the first place to look. This is especially common as a problem on unvented cylinders where the strainer has blocked or rotted away leaving a rusty blockage. Any pressurised system with a filter can display these symptoms when blocked.
