    Leak free solenoid connection

    Hello all, looking for some advice in regards to the hose going into the solenoid on the drum and not leaking. It's currently set up as shown in the picture although the hose will pop off without much pressure and also there's is leaves either side of the solenoid. This was how it was set up when I got it.

    Hi Sam,
    If it was me I would scrap the brass tap and the hose to the bend,screw in an isolater valve connected to some flexi pipe to another connecter to the bend.
    You need proper connecters with compression fitment so they wont blow off.
    Think Dave the plumber can advise better.

    i'm assuming the threaded end of the 15mm compression isolator valve is screwed into an internal 1/2" thread on the solenoid valve?
    as they usually have union type connections....looks a bit bodged tbh

    you could just use a long flexi tap type connector.
    3/4" for the hose union and a 15mm isolator tap for the other.

    or just hoselock quick connectors for the hose with a 1/2" brass nipple into what looks like your 1/2" grey polypropylene elbow?
    and 1/2" hoselock style quick connector.
    then normal 3/4" hoselock quick connector for the hose union bib/garden tap end.

    if you see how this is connected here
    i've now changed mine over to 3/8" speed fit though as i don't need that much flow...

    Thank you Dave & John, ideally I would like to keep the tap there as it is handy for water changes too, should fill the pond a darn sight quicker than through 25m of hose pipe! Will the hose lock fittings handle the pressure? Ideally I would get it to the isolation valve as it seems to be leaking from the hose side of the solenoid more than anywhere so if I could scrap that and just have the isolation valve then straight onto that it would be perfect.

    Hi Sam, I have a similar lay out to you, as I wanted a tap in the filter house.

    I put a T fitting before the tap then on the spur dropped down to 15mm speed fit plastic pipe up to the solenoid, with an isolation valve on the 15mm pipe work.

    Thanks Tom, don't suppose you could grab a picture when you get a chance? I get what you mean mostly its more the connection at the solenoid that I can't picture.

    Picture of my drum water feed,the shiney isolater valve is taken off a T further back down the white pipe then connected to the blue solenoid.
    Other part of the T goes to a tap for hose connection for cleaning purposes as Mr T above said.

    Looking at your picture maybe an isolater will screw straight into the solenoid,with some ptfe tape.

    Yes the isolator is in the actual solenoid so that's fine in that sense. Thank you for the picture John!

    Not too hard to do Sam.

    Would do it for you but a bit too far.

    Yeah it's generally just figuring out what I need and if it exists and then what the name of it is when it comes to getting things sorted!

    Heres's my set up.

    The isolation valve is handy as I can easily tweak how much water is delivered to the drum when cleaning. As I have good pressure I've dialled it back a smidge.

    Ahh ok makes sense, so the copper pipe goes up to the tap is that correct? The copper was the bit I was unsure at with Johns set up, so I could T under the tap and use a smaller quick fit hard pipe from that then?

    I think Daves suggestion would be the easiest with the least work as long as it would withstand the pressure then I would use the tap to regulate the flow.

    Yeah. Tbh the only reason I have that bit of copper and the tap was I already had it.

    If I didn't then I would've pit a tap on that fits on to the blue mdpe pipe that I have.

    I'm currently using 22mm MDPE pipe right up to the solenoid with the screw fittings.

    One point I will make is installing a water hammer arrester. Otherwise you may find all your seals/valves in the house start leaking after a while.
