Weird One with WFP system

[C Rose Cleaning Services]

I changed my filters and resin this weekend and ever since I've had a bit of an odd situation.  When I start my pump it's now taking a good 20-30seconds before any water begins to push out of the brush and then it's not up to speed for probably a full minute longer.  Also, that usual "burst" you get when you pull on the hose with a univalve fitted isn't there anymore.  The pressure seems to be building at the hose reel entry and not the exit, so when the hose is detached from the reel water flies everywhere for 30 seconds or so like the pump is still running.

The only thing I can think of that may be the cause is possibly over filling the resin vessel??  Facelift tell you to fill about 2/3's of the vessel with resin but perhaps it's more like 3/4 and the water is having a harder time getting through the resin from the pump?  Other than that I'm stumped - the controller is seemingly regulating the flow still as increasing it up and down increases and reduces the power on the pump, just now it takes a little longer for the exiting water to adjust flow?

Any help would be appreciated before I pull the resin vessel out later!

Cheers

Chris

Airlock - does your pump dead end straight away? If not you'll have an airlock somewhere. The doubt you have a blockage but that could also happen if something's dislodged when you've taken it to bits.

Funny you should ask that because no it doesn't. Takes 20-30seconds. Best to disconnect all the connections and re attach?

Ok I'm investigating. My pump as far as I can tell pushes the water through the vessel. If I disconnect at the in to resin the system Immediately DE's. If I reconnect to the system it no longer does. Takes 45seconds minimum. I've undone and reseated the vessel and it hasn't made a difference. I've tried running the pump to just a short hose and it doesn't make a difference so I can only assume the airlock is after the resin and before the pump exit on my bumper. How the hell can I clear that?!

You haven't got a hozelock with an end stop on your DI vessel have you?

Yep! Has been fine for 8 months though and this is my second resin change. I've just disconnected and sucked out a load of water and air and reconnected but having the same issue 

Well the Claber variant anyway

So you have no hose reel connected then? Mine normally air locks in the hose reel - so I just run it all out and it clears pretty much straight away. Other than that can you connect the vessel 'in' connector to your external port as your vessel might be dragging it down. The only other thing that works for me is to open and close the hose outlet (tap) every couple of seconds which - eventually - drags the water through. And the last resort - as always......... give it a suck [emoji6]

Just did that. Obviously doesn't appreciate my talents!! 

The water is coming out, just drawing slower than usual like it's tired haha. Wouldn't mind but I've not even worked 12 hours this week with the rain so it's not got any excuse!

Tuffers might be on to something with the end stop connectors - I kept having issues with the hozelock variants, for some
strange reason they just wouldn't let water through. You got any others you can try?

The Claber on the resin vessel itself? Or as a connection to my hose reel?

 

[AGlassAct]

Any of them! I had a nightmare with mine so replaced everything with rectus 026. Just test each one after the pump with everything else disconnected, then connect things one by one. Can't think of anything else as you said you have good pressure before the vessel.

You've ruled out the pump side of things as you've said when you disconnect the resin vessel it dead ends. So take the other connector off the vessel (the out) and see how fast and for how long the water comes out. Not sure what your vessel goes to straight after it - I assume it's another stop connector?

Down some microbore to my outlet valve on the bumper which is a metal fixing to plug the hose into (not sure which grade or type).

I'll try plugging the outlet into a length of hose and see if the pressure is good from there and then I'll know it's in the final couple of metres of hose and I'll suck like my life depends on it!

Mine sometimes 'creates' an air lock when I drive from job to job - once you find how to clear it you'll have no trouble in the future. Hopefully!

Just got soaked for the second time. The situation seems to be with the vessel itself?  The de isn't kicking in straight after the vessel. DE before hand no problem but if I attach a hose and lock it out the DE takes ages?

I don't have DI in my van so can't really offer any insight as to what it could be. If you've checked the claber fitting on the OUT side of the vessel then I'm clueless. Have you tried swapping the fittings over to see if the pump doesn't DE on the input side - that should rule out a dodgy fitting?

try plugging di vessel into mains water and see what happens, at full whack the sheer volume and pressure should clear any issues. If it flows out fine then you know its not the vessel

After getting soaked twice yesterday and some persistence it got a lot better today and finally spluttered for what seemed an eternity about 2pm.  There's still a lot of pressure pre hose reel but the pressure to the brush head and general start stopping and DE seems to be normal.  I had a slightly leaky port on my van which got recently tightened so that was dripping before and now it isn't I'm assuming the pressure is higher that side of the reel.

Onwards and upwards . Thanks for your help all.
