I have an intermitant problem with the jets coming form the brush head.
Every now and then the splutter almost as if there is air getting in somewhere. Somethimes for a couple of mins sometimes for very short periods.

I have An Ionics Thermopure system with 2 pumps and 2 controllers and both have the same issue at randome times. Have been onto Ionics and have tried their suggestions of checking there are no air blockages and checking for lose connections and this has not solved the issue. I have been told it could be the controllers or the pumps, both are expensive to change and cant afford to troubleshoot by purchasing either! Pluss for the sake of it spluttering its not worth fixing if too pricey.

Has anyone had a similar problem, if so what was your solution.

Ps it's not from from running the tank dry as i have bled the pumps.

If there is air coming out its getting in somewhere between the tank and the pump - simples. Jubilee hose clips (the ones you screw tight)can cause the pipe to bulge where air can get sucked in. (Use jubilee clips that are only just bigger than the pipe yu want them to seal.) We use shurflo pumps and the wing connector into the filter and/or onto the pump sometimes just needs a final tighten to get it to seal, usually done with a small adjusting spanner - but be careful. Maybe the seal on a filter bowl is not sealing properly.

I once read a suggestion to replace all suction hose with reinforced plastic see through hose and you will then be able to see where the air is getting in from where the bubbles start. Soften the hose in a cup of boiling water before pushing on to the connectors and tighten immediately while its still soft.

I too have this problem, and its murder having to get up a couple of times in the night !

Don't drink tea before bed!??

Spruce - the hoses connecting tto the pump etc are crimp fitted so cannot be tightened. Also I dont have any filters in the van as I have a static system. The connections look brand new as only just over a year old. Could try changing the hoses to clear. Other than that any other ides? Thanks for your help!

Not being funny mate but have you asked Ionics?

[Spruce]

Hi,

Is there a leak of water anywhere? ( If there is no leak it doesn't necessarily mean it's airtight) I would look at the tank outlet first.  You will have a reducer screwed into it to change the female thread to a male fitting the hose will push on  to. I would try some silicone on your finger all the way round the male fitting's thread. I would try to work it into the thread and leave it to cure. Then see if that works. If not, then its got to be the hose couplings or maybe a tiny hole in the pipe itself.

We also have a static system but both our pumps have been fitted with inlet filters/strainers to stop any dirt, accidently introduced into the van tank, from getting into the pumps.

Thinking about it there is some water ususally below the outlet taps. Ill silicone around that area and see if it sorts it. Is it easy to add a filter inline and does it effect the pressure much? Appreciate your help Spruce.

Yes have been onto Ionics but was suggested that the pumps or controllers might be faulty, but doubt both would be faulty, hopefully a leak letting air in....... Now  to find it..

Gardiners sell an inline strainer,just cut the hose from your tank to the pump and fit it on with a couple of jubilee clips and it won't affect the pressure at all

What Controllers are you using??

[Londoner]

If there is air coming through you will see it in the clear tubes on the brush head as bubbles.

What hoses are you using. If you are using 1/2" air not only can but will get trapped at the top of every loop on your reel and the flow rate is not enough to push it round and out so you get a constant "bubbling" inside the loops. Every now and then some does come free.

This is one of the main reasons why people use microbore the water can push the air round and out.

Very interesting, I need a 100m hose anyway so will see if it still does it with that. But as i type, I can rememeber igt doing it straight from the ports on the van. Oh well couple of things I can try.

Not sure what the controllers are, will have a look next time I take the pannell off. They are the ones that Ionics fit if thats any use

It may be worth looking at who supply the controller to ionics, if you can not find the air leak

[Spruce]

I'm not sure why the controllers would be a cause of this spluttering problem. If it stopped the pump and then restarted it, you wouldn't get 'spluttering'. Spluttering would be coming from compressed air.

I agree, air can only get sucked in on the inlet side of the pump and I don't know where the pump is in the ionics system but its usually low down so water only gets sucked in when the level in the tank is below the pump. Up until that point the tank acts as a header to the pump.

Or if the hose is disconnected from the outlet air will get in each time but it should get pumped through pretty quickly.
